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

I've pulled up the user manual for your phone. Thank you for providing the phone make and model first, and the complete description of your issue!

The manual says the battery should be charged for 15 hours before first use.

You may be set to pulse dialing , even though the factory default is for tone dialing. If you push the 7 key, you would hear 7 pulses or clicks in succession. The dial tone will be gone once a pulse has been received. And you say there are clicks heard and no dial tone.

You can set Handset settings (Page 12 in the PDF copy) and customize how your phone works.

Hit MENU and use the up-arrow and down-arrow keys to scroll to the desired feature., this time called DIAL TYPE, then his SELECT. Looks like the sixth menu entry from the top after LANGUAGE.

It should read:
DIAL TYPE
TONE

If it says something else, perhaps PULSE, use those arrow keys again to change the Dial Type to Tone. Then use OFF to back out of the selection and again to clear the menu.

Attached is the link to the manual. Click the button on the screen to "Open as PDF" and you can open it in your PDF reader software or save it to your device for offline reading.

If it only works in the base then it can be said that it only works when plugged into which means it has a battery problem. Rechargeble batteries expire after 1-5 years depending on their application and usage. I recommend that you replace the battery in the handset.

Good luck!

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.

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.....

no dial tone. the handset shows "searching".

deregister headsets and then run register again

i have at & t 5870 cordless phone it is no t working. handset is dead i change the battery but still not working .please give some advice.

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.

REPEAT THE REGISTRATION PROCEDURE FOR EACH SYSTEM HANDSET.

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.

I have the problem. I think it is because the battery i have in it was a Ni-MH and it should be a Ni-Cd. I am now looking for the right baterry Good luck Frank [email protected]
