Question about Motorola Mobility MD41 Expandable Handset for MD400 Series

3 Answers

Model: MD400Series I have two handset and they will not allow me to dial. I have changed the battery out just a few months ago. But with no success. It's very difficult to press the buttons on the phone. Sometimes they will press, if you press the button really hard they will dial, but most of the time it doesn't work. These are newer phones and not sure why this is happening. Thanks for any help, chris

Cleaning the contacts dod fix it. However, be careful when trying to get the phone apart.

Was the device made in China? If yes then have it replaced for one made in USA.

The electrical contact behind the buttons need to be clean with rubbing alochol and a q-tip.

Good morning! I just a bout 5 month ago this phone with its 5 handsets. In the last month 2 of the handsets dead, they are not operating ant are not charging. What I have to do. Thank

If they are not charging the batteries they will need to be replaced, but just to be sure! take a good working battery and switch out for the bad one and if the phone charges, the batteries are no good and proves the phone is good. Now! since your phones are a few months old you may still have warranty, I would encourage you to go back where they were bought to remedy the problem.

I am having problem with my cordless phone.

Another tip is to remove the battery from the handset for at least 5 seconds. You might want to get a voltage meter and check the voltage on that new battery - maybe it isn't charging properly.

How tomake outgoing calls with my american telecom digital cordless phone model#ra23634H

Thuis was hard to find but it worked for my ra2364hh's
note the phone stopped working in "tone dial" after 2 months and now functions with "pulse dial" only.....

Registration The handset and base will be pre-registered with a digital security code identification, which is stored in the phone’s memory, so that your phone will be ready to work right out of the box. However, your phone also has a procedure to allow you to re-register in case the link is lost accidentally. Enter menu, press the key - Select REGISTER and confirm PIN CODE will be displayed, enter the PIN code (the default value is 0000) and confirm. SEARCHING will be displayed while your handset is in registration mode Press and hold the Page key for 3 seconds on the base until the “In use” LED is ON, putting the base in registration mode SUCCESS will be displayed. This means the handset has located the base, and will get a handset number from the base that displays after the handset name for internal calling. If the handset does not locate the base, FAILED will be displayed and it will return to the non-located display mode that displays BS SEARCH with the antenna icon flash. Try again and check that you are not in an environment with interference. Note: Your base can register up to four handsets. If you have more than one handset, repeat the above steps to register each new handset.

TESTED IT 2 minutes ago and it WORKS.....

Vtech,5.8 3-phone w/digital recorder, model DS4122-3 None of the phones work they either say connecting or put back in the charger . these are only 2 months old?

To deregister ALL handsets:
Step 1: Press and hold FIND HANDSET on the main telephone base for 10 seconds.

Step 2: When the IN USE light starts to flash, release the FIND HANDSET button.

Step 3: Press and release FIND HANDSET again. The IN USE light will turn off and in a few seconds, all handsets will be de-registered.

Step 4: All handsets will show NOT REGISTERED.

To register a handset (register 1 handset at a time):
Step 1: Place the handset in the base unit or a charger that is connected to a power outlet. If PRESS FIND HNDST 4 SEC ON BASE does not appear on the screen after a few seconds, lift up handset and place in base or charger again.

Step 2: On the telephone base, press and hold FIND HANDSET for four seconds. Release FIND HANDSET once the IN USE light comes on.

After a while the handset will emit a series of tones, the newly registered handset will be assigned the lowest extension number not previously assigned to another system handset (1-4) when successfully registered. Repeat Steps 1 and 2 if the handset does not successfully register to the telephone base within two minutes.


Make sure the handsets are not receiving interference from other appliances, cell phones, etc.

IF deregistering does not work .. you will need to reset the entire system
Step 1: Disconnect the power to the telephone base.

Step 2: Disconnect the handset battery.

Step 3: Wait a few minutes and then reconnect the power to the telephone base.

Step 4: Reconnect the handset battery

Step 5: Wait about one minute for the handset to re-establish a link with the telephone base and then test the phone again.
You will need to set the time and date again after resetting the entire system.

Handset has No link to base

I was having the same problem with the same model phone, and fixed the problem by rebooting the phone – unplugging the AC and phone cord from the base station and plugging both back it, then removing and replacing the handset to regenerate the security code.
