Installation • If the deregistration process is not successful, you may need to reset the system and try again. To reset: pick up the registered 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. • You cannot de-register the handset(s) if a system telephone is in use. 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, then register all handsets again. To de-register all handsets 1. Press and hold FIND HANDSET on the telephone base for about 10 seconds (until the IN USE light on the telephone base 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, all handsets registered to the telephone base will show CONNECTING... and it will take about 10 seconds to complete the de-registration process. All handsets will show NOT REGISTERED if de-registration is successful. After deleting the registrations of all handsets, you will need to individually register each handset with the telephone base (see page 6 for registration instructions).
