Question about Siemens Gigaset 4210 Cordless Phone

Handset flashes "searching" and has stopped working

The handset continues to flash the word searching. I have the user manual and have tried to register both the handset and base with no luck. I even reset the handset to the factory default setting with no luck. Is it time to buy a new cordless phone or can this problem be solved? I could not find a solution in the user manual.

Did you already try cleaning the connections on the phone and the base with alcohol on a Q-tip? Make sure the connections on the phone are touching the base propely.

I am trying to replace a handeset on my E5640 answering system. I have followed the procedures to deregister the existing handsets but it will not accept the base code for the last one. The handset I am...

  • Your telephone can accommodate up to four cordless handsets. You can add new handsets (Model E560-2, sold separately) at any time, but each must be registered with the base before use.
  • The handset provided with your telephone is automatically registered as Handset 1.
  • Additional handsets will be assigned numbers in the order they are registered (2, 3 or 4). You can register a maximum of four handsets.
To de-register all handsets
• Unplug the power supply from the base unit.
• Remove all handsets from the charge cradles and base.
• Plug in the power supply while pressing and holding the HANDSET LOCATOR button.
• Continue pressing HANDSET LOCATOR until the IN USE and CHARGING indicators are lit (this could take up to 10 seconds).
• Release the HANDSET LOCATOR button.
• All handsets will display: ENTER BASE ID: XXXXXXXXXX
Once the base indicators turn off (up to 30 seconds), the handsets have been de-registered from the base, and can now be re-registered.

To re-register a handset:
• Make sure your handset batteries are properly installed and charged.
• Your handset will display "ENTER BASE ID".
• Enter the 15-digit Base ID number from the bottom of the base unit.
• Press SELECT to accept the new code and complete re-registration.

To re-register a handset to a new base unit:
• Make sure your handset batteries are properly installed and charged.
• Unplug the old base unit. Your handset will display "SEARCHING...".
• Install the new base unit by plugging it into an electrical outlet and phone jack.
• Press and hold the SELECT key until the handset displays "ENTER BASE ID".
• Enter the new 15-digit Base ID number from the bottom of the new base unit.
• Press SELECT to accept the new code and complete re-registration. The handset is now registered to the new base.

I cannot use the cordless part of my panasonic KX-TC1221BXB. The following message is shown ''No link to base. Place on cradle and try again'' But even after placing back on the cradle, the same message is...

I couldn't find the exact manual for your phone but I would try to re-register the phone. Following are some instructions for similar models of your phone.

*To do this on a non-expandable cordless phone:
  • Press and hold the LOCATOR/INTERCOM button on the Base until a beep sounds.
  • Press and hold the FLASH/CALL WAIT button on the Handset until a beep is heard.
  • When registration is complete, a beep sounds from the handset.
  • Wait for 20 seconds after registration is complete to allow the handset to establish communications with the base.
If this fails to help: Remove the AC Adapter from the phone base or wall outlet for a few seconds and reconnect. It may also be necessary to remove the battery from the handset for a brief moment.

Good luck!

Handset won't work

I went through this exercise with a Siemens Gigaset 8800. The solution is to DE-register the handset first. Then register it with your base. This function can likely be accessed in the handset menu. The phone you purchased is apparently still registered to the previous user's base.

1. close the handset (long-press red button)
2. discconect the base unit from the power source
3. reconnect to the power source and long press the intercom (the only button on the base unit) for 5 seconds.
4. turn on the handset (long-press red button)
with 2 seconds and it will be connected again.

hope this helps.

VTech 5.8 mhz won't work

I found a solution that fixed this problem (at least for me). On the vtech site they said to unplug the base unit for at least 5 minutes. Previously, I had only unplugged the base unit for a few seconds. This time, I left it unplugged for about 10 minutes or so and when I plugged it back in, everything was working fine. Apparently there is some sort of capacitor that must discharge long enough to completely remove power from the circuitry.

Good luck and I hope this works for you!

Panasonic Phone KX-TG6700B base unit Problem

FROM PAGE 38 of the manual:

If "No link to base. Move closer to base, try again" is displayed, even when using the handset near the base unit, the handset may have lost communication with the base unit. You need to re-register the handset to the base unit..

1-Base unit:
Press and hold [HANDSET LOCATOR] until the CHARGE indicator flashes.
Press and hold [FLASH/CALL WAIT] until "Handset Registering" is displayed.
-When registration is complete, a beep sounds from the handset.
-Wait for 20 seconds after registration is complete while the handset establishes communication with the base unit.

If... the handset beeps three times and "ERROR!" is displayed, an error occurred. Try again from step 1.
You can stop registration by pressing [OFF] on the handset, and pressing [HANDSET LOCATOR] on the base unit.

Registering a new phone

With a little searching I was not able to confirm this phone could handle more than one cordless handset. Are you replacing a defective handset or trying to add a second. If adding, do you know if it can handle the second unit (is it advertised on the box, in the user guide, etc?) If replacing, you most likely have to de-register the old handset on the base unit before you can register a new one. If you are adding, try de-registering the working handset anyway and registering the new one. If the new one registers and you cannot re-register the once working phone you will know either the system cannot handle two phones or (if the new one will not register but you can again re-register the original) that the new handset has a problem and should be returned.
