Installing/Replacing the Memory Back-up Battery
Disconnect power before installing or replacing the battery.
Do not install the memory battery until the BW500 is to be used.
The unit is supplied with one
battery package (battery P/N
20200035 or Rayovac #BR2335,
3V, Lithium or equivalent). Remove
the battery from the package and
insert it into the battery socket.
The memory battery (see
Specifications) should be replaced
every 5 years to insure memory
back up during lengthy power
outages. An on board capacitor
provides 20 minutes of charge in
order to preserve the memory
while the battery is being changed.
