The base phone has a 
dial tone but none of the 
keys are working. It has 
worked before; is the 
base broken?

L

Ensure that the memory card and memory card cover 
are not pressing down any of the intercom/transfer 
keys. See page 19 for details on how to install the 
memory card.

Backup battery:
How long will the base 
unit retain its memory 
after a power failure?

L

The rechargeable NiMH backup battery will maintain all 
functions of the base unit for a minimum of 20 minutes 
in the event of a mains power failure. See page 11 for 
more information about the backup battery. 

L

If the backup battery becomes exhausted during a long 
power outage, messages stored in the base unit’s 
memory are maintained indefinitely in flash memory.

Call monitoring:
How can I disable the call 
monitoring feature to 
prevent others from 
hearing my incoming 
calls?

L

You can temporarily disable the call monitoring feature 
by pressing {MUTE}.

L

The call monitoring service can also be programmed to 
remain off, if necessary. See page 85.

Resetting the base unit:
My base unit has stopped 
working, cordless 
handsets cannot link to it, 
and new cordless 
handsets cannot be 
registered. How can I 
reset the base unit?

L

If the base unit becomes locked and stops working, you 
may need to press the {RESET} button to resolve the 
problem. The {RESET} key is located on the underside 
of the base unit and must be pressed with a pointed 
object. See page 99.

Resetting the cordless 
handset:
My cordless handset has 
stopped ringing and there 
is interference. How can I 
reset the cordless 
handset?

L

When the cordless handset stops ringing and 
interference is heard, you can remove the battery for at 
least 30 seconds and then replace it to reset the device.
