Getting started

Replacing a handset

When you are replacing rather than adding a handset, for your handsets to be numbered sequentially, you need to delete all the handset registrations on the telephone base.

To de-register all handsets

1.Press and hold FIND HANDSET on the telephone base for about 10 seconds (until the IN USE light turns on and starts to flash), then release the FIND HANDSET button.

2.Immediately press and release FIND HANDSET again. You must press FIND HANDSET while the IN USE light is still flashing. The IN USE light will flash for approximately seven seconds.

3.Soon the handsets will show CONNECTING... and it will take about 10 seconds to complete the de-registration process. All handsets will show NOT REGISTERED if deregistration is successful.

NOT REGISTERED

After deleting all handset registrations, you will need to individually register each handset with the telephone base (see page 4 for registration instructions).

NOTES:

1.If the de-registration process is not successful, you may need to reset the system and try again. To reset: pick up the handset and press

the /FLASH button, then press the OFF/CLEAR button and place the handset back into the telephone base. You may also reset by unplugging the power from the telephone base then plugging

it back in.

2.You cannot de-register the handset(s) if any telephone connected to the telephone line is in use.
