Our take on the Panasonic KX-TG6511B

Panasonic's KX-TG6511B expandable phone system gives you clear conversation with reduced noise and expanded cordless range. The handset features a large 1.8" screen and Caller ID so you can easily see who's on the line. The keypad lights up for easy dialing at night, and the locator button on the base unit helps you find the handset anywhere in the house.

Panasonic's KX-TG6511B expandable phone system gives you clear conversation with reduced noise and expanded cordless range. The handset features a large 1.8" screen and Caller ID so you can easily see who's on the line. The keypad lights up for easy dialing at night, and the locator button on the base unit helps you find the handset anywhere in the house.

Put unwanted callers on the phone's Call Block list, and when they call, they'll simply get a busy signal. If you want to turn off the ringer when you go to sleep, just switch the handset to "Silent Mode" and you won't hear a sound. But don't worry about missing an important call if you forget to turn the ringer back on — the handset's light-up indicator will still alert you when a call comes in.

DECT cordless technology
The KX-TG6511B uses DECT (Digital Enhanced Cordless Telecommunications) technology for clear conversations with reduced noise and excellent cordless range. It operates on the 1.9 GHz frequency bandwidth, so it won't interfere with Wi-Fi® computer networks or other common wireless devices. If you want to expand this system to accommodate a large household or small business, you can add up to five more handsets — for a total of six — still using just one phone jack.

Product Highlights:

  • uses DECT 6.0 cordless phone standard
  • 1.9 GHz frequency range avoids interference with Wi-Fi networks
  • multi-handset operation (add up to 5 optional handsets for a total of 6)
  • 1.8" white, backlit LCD display on handset
  • lighted handset keypad
  • 50-entry Caller ID memory and 50-entry phonebook memory
  • 30-entry Call Block list
  • 3-way conferencing between outside line and up to two handsets (one included)

  • voice paging (base to all handsets)
  • jack for optional headset
  • wall mountable base
  • NiMH rechargeable batteries (two AAAs)
  • warranty: 1 year
  • Our 60-day money-back guarantee

So far this phone has been great. Very clear on each end, Reception has been great. Does not interfere with wifi or small appliances.

The Perfect Phone

Madeline M from Southgate, MI on 11/30/2013

Crutchfield Customer Review (What's this?)

This is the exact phone that I had been searching for. I wanted a simple phone with no bells and whistles that I knew that I would never use. At first I believed that I would have no choice but to purchase more phone than I needed. So, when I discovered this phone that Crutchfield had to offer, I was delighted. The phone has a large display so I don't have to use my readers everytime the phone rings to see my caller ID feature! :)

Pros: Simple to use, large display window, large phonebook capacity.

Cons: Some functions take more steps than necessary...just need to get used to it.

Crutchfield Customer Review (What's this?)

Once use to it, great phone ! 30 phone number block. My company charges for call block & for close to $10.00 a month, you only get an eight number block. With the Panasonic blocking up to 30 numbers is free. WAY TO GO MY FRIENDS AT CRUTCHFIELD !

Pros: 50 Phone number directory. 30 number capabile call block. 6.0 + digital clarity. 30 number call log. Swivel mountable base. Handset runs on aaa's battery's & not some odd handset battery ordered from the co. or other electonic place.

Cons: A little of time needs spent to get use to the phone but afterwards, easy & practical. Great phone.

Good sound, great value decent price

Crutchfield Customer Review (What's this?)

Was in need of a new cordless phone and this one did the trick! So far so good, and no complaints. Really for the money, it's a nice value with good features.

Pros: Good value,nice features

Cons: None


Maggie from Asheville, NC on 4/21/2012

This is a great phone in every way...except it has no speed dial! Why would they not include such a basic feature? I never even thought to check that in the specs when I was shopping for a phone; I assumed it was standard, since phones have had them for 15 years! It's a big negative for me.


Cons: No speed dial

Telephone Features

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-TG6511 phone will not conflict with other wireless devices such as computer routers, wireless keyboards, microwave ovens and other common household devices.

Expandable Cordless System: In addition to the included cordless handset, you can add up to five more KX-TGA651 (133TGA651) 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" LCD screen which 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 Keys: The four directional navigator keys on the handset are used to navigate through menus and to select items shown on the display by pushing it up, down, left, or right.

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.

Ringer/Message Indicators: The handset has a ringer indicator LED on the top that will flash quickly whenever a call comes in.

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.

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, the # key, or the intercom button 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 two "AAA" rechargeable Nickel-Metal Hydride (Ni-MH) batteries for the handset. A Ni-MH battery doesn't develop the "memory" effect like many Nickel-Cadmium (Ni-Cad) rechargeable batteries.
