immediately.
In all circumstances the battery must also be
replaced at least once per year.
To replace the battery, remove the Warning
Handset from its cradle. The Handset will emit
an audible warning to indicate that it has been
removed.
Remove the battery cover and replace the battery
as per the instructions in “Fitting the Battery”. (See
page

)
Use only the following batteries:
Duracell Ultra, Duracell MN 1604, Engergizer
Ultra+, Energizer 522 or Gold Peak 1604A 9V,
ULTRALIFE U9VL Lithium

Signal Failure
Operation of the Warning Handset depends
on receiving a radio frequency (RF) signal from
Wi-Safe alarms in order to respond to an alarm
condition. Nearby electronic equipment may,
will emit a single chirp once every minute. The
Warning Handset should be replaced in the cradle
as soon as possible to prevent premature discharge
of the internal battery. This warning feature also
helps to reduce the risk of the Warning Handset
being removed from the area undetected (for
example, by a child).
The Warning Handset will still respond to an
alarm condition if left out of its cradle, provided
there is sufficient battery power remaining. When
an alarm signal is received, the Handset will initially
react as per step “
B
” of “basic function” (see page
16). If the alarm condition persists for more than
30 seconds, the remote will automatically become
a torch and locator (step
C
of “Basic Function”).

Battery Replacement
The battery must be in good condition to operate
the Warning Handset reliably. If the low battery
LED flashes at the same that a warning chirp is
given (once per minute), replace the battery
