I cannot get my Panasonic base KX-TG5583 to register 8th handsets - only seven

The KX-TGA401C handset works with the KX-TG401x, KX-TG403X and KX-TG651x phone systems among others. If you have the appropriate base, see the suggestions below.

Does your handset read Ringer Off? Try setting the ringer volume. With the phone system in standby (no calls in or out for any handset), press Menu. Navigate using the Up/Down arrows to Initial Settings. Press Menu/OK. Navigate to Ringer Settings and press OK. Press OK again to enter the Ringer Volume sub-menu. Use the Up/Down arrows to set the ringer volume and press OK to save. Press Off to exit the menu system.

The other possibility is that the handset is not registered to the base. Note: only 6 handsets can be registered to the base. If you previously registered 6 handsets, you need to deregister some of them.
To register the handset, hold the handset near the base since you will need to press buttons on both. Press Menu on the handset and navigate to and enter Initial Settings. Navigate to Registration and press OK. Navigate to HS Registration and press OK. On the base, press and hold the Locator button for 5 seconds and the registration tone sounds. Press OK on the handset you are trying to register. If all the registered handsets start ringing, you triggered the Locate handset function. Press the Locator button again. Then do the press and hold step again. Only press OK on the handset when you hear the registration tone.

You can find the manual for the KX-TG4011 here: https://shop.panasonic.com/support-only/KX-TG4011N.html . The direct link to the manual is https://ftp.panasonic.com/telephone/om/kx-tg4011_mul_om.pdf . See page 21 for the directions to set the ringer volume.

I hope this helps.

(You can't register a handset to an incompatible base. The communication protocols don't work.)

The KX-TGA401 is a handset for specific Panasonic cordless telephone systems. Connecting the handset requires registering (pairing) it with the base and if the base can support another handset. First make sure that the base is plugged into an active phone line (land line) and that the power adapter is plugged in and working properly. Charge the handset before attempting the registration process.

Then make sure that the phone system is in standby (no calls). Press and hold the Locator button on the base for about 5 seconds (wait until the tone sounds). If all of the handsets that are already registered ring, press and release the Locator button and then press and hold it again. Once you hear the registration tone (some models), place the new handset in the charger on the base. Wait for the long beep and the registered symbol to appear.

If the not registered symbol appears, try registering by using the handset menu. Press Menu # 1 3 0 (the key below 9 and individual number keys) on the handset. Press and hold the locator button until you hear the registration tone as above. Then press Select and Save on the handset within 90 seconds of hearing the registration tone. Wait for the handset and base to complete the registration process. You'll hear a long beep.

The first registration method is given in the manual for the handset, http://help.panasonic.ca/viewing/ALL/KX-TGA401/OI/TGA401_PNQX2390ZA/TGA401_PNQX2390ZA.pdf. The second is from the page 31 of the manual for the KX-TG653x (KX-TG6531 base) system, ftp://ftp.panasonic.com/telephone/om/kx-tg6511_mul_om.pdf . The KX-TGA401 handset works with other bases as well. You may want to check the manual for your phone system in case there are differences. Other compatible phone systems are the KX-TG401x, KX-TG403x, and KX-TG651x.

I hope this helps.

(I make sure that the land line is active by checking for dial tone with an old corded phone.)

The stored block numbers should be saved. The database is in the base's memory. Since the KX-TG6843 base can support a total of 6 KX-TGA680S handsets, you can purchase and register 3 new handsets. If needed, you can de-register the old ones from any working handset and then add even more. See page 35 of the manual, ftp://ftp.panasonic.com/telephone/om/kx-tg6841_mul_om.pdf . Additional handsets are available from Panasonic, http://shop.panasonic.com/support-only/KX-TG6843B.html , Scroll down to the Accessories section and expand it. Amazon.com also has the handsets: https://www.amazon.com/Panasonic-KX-TGA680S-DECT-Accessory-Handset/dp/B00BS4D2CU .

I hope this helps.

335 is the magic code when you want to remove a previous handset or base station registration!
Handset:

1 " (middle soft key) i L i #

2 Enter "335".

3 "Cancel Handset" i #

LThe numbers of all handsets

registered to the base unit are

displayed.

4 Select the handset(s) you want to

cancel, by pressing the desired handset

number. i #
5 "Yes" i # i {ih}
Base Station:

A handset can be registered to a maximum

of 4 base units. A handset can cancel a base

unit that it is registered to. This allows the

handset to "forget" the base unit.

1 " (middle soft key) i N i #

2 "Registration" i #

3 Enter "335".

4 "Cancel Base" i #

5 Select the base unit(s) you want to

cancel, by pressing the desired base unit

number. i #
6 "Yes" i # i {ih}

You need to contact Panasonic's customer service.

I had this problem, and I fixed it by re-registering the phone to the base. Here are the directions for how to do that from the manual:


----->

Registering a handset to the
base unit
The supplied handset and base unit are
pre-registered. If for some reason the
handset is not registered to the base
unit, re-register the handset.
1 Handset:
{MENU}
2 {V}/{^}: "Initial setting"
{OK}
3 {V}/{^}: "Registration"
{OK}
4 {V}/{^}: "HS registration"
{OK}
5 Base unit:
- KX-TG4011 series:
Press and hold {LOCATOR} for
about 5 seconds. (No registration
tone)
- KX-TG4021/KX-TG4071 series:
Press and hold {LOCATOR} for

about 5 seconds until the
registration tone sounds.
If all registered handsets start
ringing, press the same button to
stop. Then repeat this step.
The next step must be completed
within 90 seconds.
6 Handset:
Press {OK}, then wait until a long
beep sounds.
Note:
While registering, "Base in
registering mode" is displayed on
all registered handsets.
When you purchase an additional
handset, refer to the additional
handset's installation manual for
registration.
