4.1 Battery Replacement
20
If the battery replacement indicator is blinking
when power is turned on, the battery is running
low. Replace with a new battery.
1. Turn off power and disconnect the optical fiber
cable from the 3662-20/3663-20.
2. Remove the setscrew and open the battery
cover.
3. Replace both batteries.
4. Replace the battery cover and tighten the set-
screw.
• The battery replacement indicator appears when
battery voltage becomes low. Replace the batter-
ies as soon as possible.
• Use the specified battery (LR6 alkaline battery)
only. Other batteries, (manganese batteries, for
example) run out more quickly than alkaline bat-
teries.
