thunderstorm as it is possible to get an electric

pages directory.
BATTERY BACK-UP (Battery not supplied)
It's not necessary to install a battery for the clock to
function. You can install a 9 volt alkaline battery to keep
the time and alarm settings in the event of a power cut or
the AC adaptor being unplugged for any reason.
We recommend you replace the old battery every 12
months, if there is frequently power outage, the battery
need to be replaced more frequently. A leaking battery
can destroy your WNS1.
INSTALLING THE 9 VOLT BATTERY
- Before installing or changing the battery make sure that the
telephone is not connected to the telephone network or the mains
power supply.
- Install a new 9 volt alkaline battery.
- Replace the battery door.
