Our take on the Panasonic KX-TG6644B

by Ralph Graves
Panasonic

Panasonic's KX-TG6644B expandable phone system gives you clear calling and convenient features. The tone equalizer lets you adjust the phone for the way you hear — independently raise or lower the low, high, and mid-range tones for greater clarity. Talk with the phone perched on you shoulder while you do other things? Who doesn't! The handsets have non-slip rubberized grips, so they're easier to keep on your shoulder, and out of the dishwater.

A large screen and backlit buttons make receiving calls and dialing easy. Or you can let the phone do the talking — when a call comes in, Talking Caller ID announces who's on the line. You can even put unwanted callers on the phone's Call Block list, and when they phone you, they'll simply get a busy signal.

Go ahead and turn off the ringer when you go to sleep — you won't hear a sound, but you won't miss any calls. In Silent Mode, the handset's light-up indicator will still alert you when a call comes in or when you have a message on the built-in digital answering machine.

Need a few extra phones? You can expand this system by adding up to two more handsets — for a total of six — and still use just one phone jack.

DECT 6.0 Plus cordless technology
The KX-TG6644B uses DECT (Digital Enhanced Cordless Telecommunications) 6.0 Plus technology for clear conversations with reduced noise and improved cordless range. DECT Plus increases error protection up to 80X over previous DECT technology, giving you the cleanest possible sound, at the maximum possible range. And it operates on the 1.9 GHz frequency bandwidth, so it won't interfere with Wi-Fi® computer networks or other common wireless devices.

  • uses DECT 6.0 Plus cordless phone standard
  • 1.9 GHz frequency range avoids interference with Wi-Fi networks
  • multi-handset operation (add up to 2 optional handsets for a total of 6)
  • handsets feature rubberized non-skid grips

Telephone Features

DECT 6.0 Plus: DECT (Digital Enhanced Cordless Telecommunications) Plus technology improves on the original DECT 6.0. The error correction frequency is increased up to 80x, which increases the range and improves the transmission quality. Operating in the 1.9 GHz frequency range, the KX-TG6644 phone will not conflict with other wireless devices such as computer routers, wireless keyboards, microwave ovens and other common household devices.

Range Boost: The KX-TG6644 has a new built-in antenna to the base unit for extended transmission range. This Range Boost antenna technology provides up to 20% improvement in talking quality (in an open space), as compared to previous generation Panasonic DECT 6.0 PLUS phones.

Expandable Cordless System: In addition to the four included cordless handsets, you can add up to two more KX-TGA660 handsets, for a total of six.

Intelligent Eco Mode: The phone's Intelligent Eco mode automatically reduces handset power consumption when you're using the handset close to the base unit. This feature extends the available talk time by suppressing the power it takes to transmit to the base unit. The "ECO" icon appears in the handset display when activated.

Handset Speakerphone: The cordless handset can double as a speakerphone for hands-free conversations. The handset is squared on the bottom, allowing you to stand it up on a table top while you talk hands-free.

Non-Slip Handset: The KX-TGA652 handset has a rubberized surface on the back panel to help prevent slipping, especially when you cradle it on your shoulder.

Headset Compatible: The handset has a 2.5mm sub-mini headset jack to allow you to plug in a headset for hands-free operation. Compatible headsets include: KX-TCA400, KX-TCA60, KX-TCA93, KX-TCA94, and KX-TCA430.

1.8" Backlit LCD: The cordless handset features a backlit 1.8" Full-dot Mono LCD screen with a resolution of 103 x 65 pixels. The handset LCD displays Caller ID information, battery strength, Caller List, Directory, plus the Function Menu table. You can adjust the contrast of the LCD from 1-6.

Navigator Key: The navigator key on the handset is used to navigate through menus and to select items shown on the display by pushing it up, down, left, or right. You can easily adjust the receiver or speaker volume by pressing the navigator key up or down as you talk.

Soft Keys: The handset has three soft keys which allow you to select the feature shown directly above it on the display. Some of the soft key functions include Mute, Phonebook, Menu, and Redial.

Caller ID: This unit is compatible with Caller ID services offered by your telephone company. If you subscribe to Caller ID, the caller's name and phone number will be displayed and recorded in the handset's Caller List.

Call Waiting Caller ID: If you subscribe to Call Waiting with Caller ID, when talking on the phone as another call comes in, the second caller's name and phone number will be displayed.

Talking Caller ID: Talking Caller ID lets you know who is calling without looking at the display. When the caller information is received from your Caller ID service, the handsets and base unit announce the caller's name or phone number received after each ring.

Ringer/Message Indicators: The handset has a ringer indicator LED on the top that will flash quickly whenever a call comes in, or slowly when you have a message or voice mail waiting. When the answering machine has received a message, the message indicator inside the "Play" button will flash. Note: The message alert feature must be "on" in order for the message indicator to operate.

Caller List: The unit records information for the last 50 callers and stores this information in the Caller List. The unit can show the number of calls you missed. You can call back any number in the caller list. Once a number is in the Caller List, it can be manually or automatically edited (to add or remove area codes or prefixes), saved in the Directory, or deleted.

Call Block: The phone can be programmed to reject unwanted calls. If you subscribe to Caller ID, the unit will reject a call that comes in without a phone number, including those that are labeled "Out of area", "Private caller", or "Long distance". Calls from a phone number stored in the call block list are also rejected. Up to 30 phone numbers can be stored in the call block list. When the call is received, the unit rings for a short time while the caller is being identified. If the phone number matches an entry in the call block list, the unit sends out a busy tone to the caller, then disconnects the call.

Shared Phonebook: All handsets registered to the base unit can use the unit's phonebook. Up to 50 names and phone numbers can be stored in the phonebook. You can enter names up to 16 characters, and phone numbers up to 24 digits. A pause can be entered in the phone number if required for dialing. Each pause is stored as one digit and the pause is approximately 3.5 seconds. The directory names are sorted alphabetically. You can also assign names to one of nine groups to help you locate entries quickly and easily. Groups can also be assigned a different ringer tone to help you identify who is calling.

Chain Dial: You can dial a number from the phone while on a call using Chain Dial. This can be used to dial a calling card access number, dial a PIN number, etc. without having to dial it manually.

Redial List: You can review a list of the last five numbers dialed, then call any of those numbers.

Mute: This system features a Mute key on the cordless handset. If you wish to temporarily mute the conversation, you can mute the handset so the other party cannot hear you, but you can still hear them.

Handset Locator: This feature allows you to locate a handset by paging it from the base unit. All registered handsets are paged simultaneously.

Silent Mode: You can program each handset to ring or not at your discretion. If you set a handset to Silent Mode, it will not ring when calls come in. A specific time period can be programmed ahead of time for the silent mode. Other handsets programmed to the phone are not affected, and will continue to ring when calls are received.

Intercom: This feature lets you set-up a 2-way conversation between two registered handsets.

Call Transfer: Calls can be transferred from one handset to any other registered handset.

Privacy Mode: You can prevent users of other handsets from joining your conversations by engaging the Privacy Mode in the Initial Setting menu. To allow other users to join your conversation (call share), you can turn the Privacy Mode off.

Call Share: Call Share allows a second registered cordless handset to join an existing external call by pressing one button.

Any Key Talk/Auto Talk: The Any Key Talk feature allows you to press any of the numeric keys, the * key, or the # key to answer a call. When the handset is on the charger base, the Auto Talk feature allows you to answer a call by simply picking up the handset. Auto Talk can be turned on/off in the menu.

Volume Controls: You have the ability to adjust volume levels for the handset and the handset speakerphone. Choose from four levels when holding the handset to your ear, and six levels for the speakerphone.

Ringer Options: You can select one of six ringer volume settings or Off. You can also choose between five ring tones and five ring melodies.

Temporary Tone Dialing: If you are using a pulse dialing system, you can temporarily switch to tone dialing to enter numbers for answering services, electronic banking services, company phone directories, etc. When you hang up, the mode switches back to pulse dialing.

Flash Key: If you have the Call Waiting service, you can use the flash key to put the first call on hold, allowing you to answer a second incoming call. You can adjust the length of the flash time if necessary.

Alarm: On the handset, you can set an alarm to sound for three minutes on a one-time or daily basis. With the date and time programmed into the phone, you can enter a desired time for the alarm to sound. Using a different ringer tone from the one used for outside calls is recommended.

Belt Clip: The included belt clip can be attached to the back of the cordless handset so that you can hook it onto your belt.

Security: A handset cannot operate unless it is registered with the base unit.

Battery Information: The phone comes with eight "AAA" rechargeable Nickel-Metal Hydride (Ni-MH) batteries, two for each handset. A Ni-MH battery doesn't develop the "memory" effect like many Nickel-Cadmium (Ni-Cad) rechargeable batteries.

  • Initial Charge Time: 7 hours
  • Battery Talk Time: up to 13 hours continuous
  • Battery Standby Time: up to 11 days

Power Back-up Operation: When there is a power outage, the charged handset in the base temporarily supplies power to the base unit. This allows you to make and receive calls using a handset during the power outage. Assuming fully charged batteries, you can use the base handset continuously for up to 2 hours, or one of the other handsets continuously for up to 3 hours, or in standby for up to 3 hours.

Wall Mounting: The base unit and battery charger for the additional handsets can be placed on a desk or table, or can be wall mounted. The base unit has an integrated bracket that can be turned one way for wall mounting and turned the other way for placing on a desk. The battery charger has two keyhole slots for wall mounting.

Answering System Features

Total Recording Time: The total time for recording is approximately 18 minutes for all messages (including greeting). A maximum of 64 messages can be recorded. All messages are saved until you delete them. When the memory is full, an indicator on the base unit flashes rapidly, "Messages Full" is shown on the handset display, and, if you use the pre-recorded greeting message, the unit automatically switches to another pre-recorded greeting that asks callers to call again later.

Caller's Recording Time: You can select 1 minute or 3 minutes for recording incoming messages. Individual messages can be played back and erased from the base unit or the handsets.

Greetings: You can record a personal greeting of up to 2 minutes. The unit also comes with 2 pre-recorded messages; one used when the unit has no available recording time, and one used when a message will be recorded.

Number of Rings: You can set the number of rings before the answering system answers the call. Your choices are 2 to 7 rings, or Toll Saver. When set to Toll Saver, the unit will answer on the second ring when there is at least one new message, or on the fifth ring when there are no new messages. This allows you to save on toll charges for the call by hanging up when you hear the third ring, knowing there are no messages.

Call Screening: You can listen to an incoming message as the caller leaves it using the handset's speaker.

Voice Day/Time Stamp: With each message the unit announces the day and time the message was recorded.

Message Alert: When a new message has been received, the message indicator on the base unit will flash, and "New Message" is displayed on the handsets' display.

Remote Operation: You can operate the Answering System from any touch-tone phone. The system is protected by a three-digit remote code to prevent unauthorized access. You can either use the unit's voice prompts (in English or Spanish) or direct commands by pressing keys. During remote operation, you can perform the following functions:

  • Playback all messages or playback new messages only
  • Repeat or skip a message
  • Play the greeting
  • Record a new greeting
  • Erase currently playing message or all messages
  • Turn the answering system on or off

Voice Mail Services: The KX-TG6644 will integrate with your telephone company's voice mail service to make it easier to retrieve your messages. When you receive a new Voice Mail message, the telephone company sends special tones to alert you that a new message is available. The KX-TG6644 detects these tones, causing the message indicator on the handset to flash slowly, and by displaying "New Voice Mail" in the LCD. You can program your Voice Mail access number (along with your password and any necessary pauses) so you can dial it automatically to retrieve your messages.
