Re: PROBLEMS with phone

Had the same issue. I have two units each with a handset, and one handset went to "out of range" status and stayed that way even after recharging. I tried to register it with that base and no luck. I then tried to register it with the other base and it worked. Then I tried to "swap" the handsets and no luck - it seems that the registration process on the one unit is toast so now I can only use the handsets with one of my two base units.

I cant dial out it says register HS i am not familiar with the procedure.

When you reset a handset (or if you buy a new one1, that handset displays a Handset Not Registered message. If you see this message on a handset, you need to register it to a base before you can use it.
Registering a handset
Does the handset fit in the base cradle?
Place the handset in the base.
The display should say Handset Registering.
1. On the base, open the menu and select Register Handset. The display should say Handset Registering.
2. On the handset you want to register, press and hold # until the handset display says Handset Registering (about 2 seconds).
In about 30 seconds, the handset display should say Registration Complete. Press TALK ( )/FLASh and make sure you get a dial tone. page29image32024
- you don't hear a dial tone- the display says Registration Failed
Making sure the handset is fully charged, then start over at step 1.
To register a handset to a different base, see the section "Expanding Your phone" in the user's guide for the other base.

My gigaset c610h wont register

You can try to put the base in registering mode by using the web interface. Check your base user manual for further details.

The other plausible reason: Have you checked the DECT frequency range operation? My base was bought in Europe (1880~1900MHz) and the handset was bought in USA (1920~1930Mhz). So they are incompatible. :-(

Bought a spare 3111 handset and cant connect it to my base. it looks as if it was connected to another base at one time. screen just says "connecting..." and there is nothing I can do to clear...

The handset must be registered to the base unit if the system has multiple handset ability, the manual will tell how to register the handset. If the system is a two handset system then only two handsets can be registered.

I have a Motorola L404 cordless phone. i bought an additional handset. I cannot get it to register with the base unit. It just keeps saying "registration failed"

On the Motorola L404 series, to deregister all handsets you unplug both the phone and power to the base station. Press and hold the 'find' button while plugging the power back in. The display will show "CL". Continue to hold the find button till the display shows '00' and all the handsets will show 'unregisterd'. You then proceed by registering all your handsets again in the order you want them listed.

The "END" and "#" key combination can be used for several purposes:

1) If wanting to use an ALREADY REGISTERED HANDSET on an alternate base, and if if the INITIAL BASE isn't available to deregister the handset:

1a) Press "END" + "#" until it for 5+ seconds (wait for it to beep)
1b) Choose the "Base Unavailable" option
1c) That'll deregister the CURRENT HANDSET so that it can be re-registered on ANY base.

2) If a BASE has a handset registered to it which you no longer want registered but the registered handset is missing or broken:

2a) Grab another WORKING handset which is properly REGISTERED to the BASE in question
2b) Press and hold the "END" + "#" key for 5+ seconds (wait for it to beep)
2c) Choose the "Deregister HS" menu option
2d) Pick the REGISTERED HANDSET # to de-register. (Every other registered handset EXCEPT THE ONE YOU'RE ON will appear in the list!)

Programming old handsets to a new base

Cancel the old handsets registration at the previous base unit if desired.
For additional handsets, you must register each of them at the new base unit. Only one handset can be registered at a time. A handset will be assigned anextension number at registration.

Make sure the base unit and the other handsets are not being used. Program the same way as the extra handset you bought.

Registration must be completed within 1 minute.
