Microtel Series 200 - Manual (Page 8)

D. BATTERY INSTALLATION
The battery is installed at the bottom of the system, in the battery tray provided as
part of the interior chassis assembly.
IMPORTANT! Before installing the system battery, be certain the power supply
transformer is not plugged into an electrical outlet.
Remove the four phillips head screws which secure the system's front panel and
remove it to expose the system's interior. Note that the panel is still connected to the
system's main circuit board, so care must be exercised while the panel is hanging on
this "tether". Retrieve the red and black battery leads from within the battery tray.
Push the battery lead terminals on to the new battery, BEING CERTAIN that the red
lead connects to the positive (+) battery terminal, and the black lead connects to the
negative (-) battery terminal.
Slide (do not force) the battery completely into the battery tray with the terminals
pointed DOWN into the system. If the battery is not completely seated in the battery
tray, the front panel will be obstructed and will not fit properly onto its mounting area.
A new battery will take no longer than 24 hours to gain a full charge, capable of
powering the system through any power outage up to four hours in length. It should be
noted that the LOW BATTERY indicator is only valid when the 120 vac power is on. If
the LOW BATTERY indicator stays on for more than eight hours, the battery is in
need of replacement.
