MAINTENANCE AND TROUBLESHOOTING
In the unlikely event that trouble is suspected with the system, it must be promptly

available to qualified personnel.
Periodically inspect the system internally for any evidence of moisture, blown fuses,

A. MAINTENANCE
1. Battery
Care
Battery life is dependant upon a number of factors, and will vary depending on the
number of outages, and the age of the battery. 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.
The battery installs at the top of the system, in the battery tray provided as part of the
interior chassis assembly.
It is necessary to remove power from the system by throwing the supply circuit
breaker or removing the power plug from the wall outlet before replacing the battery.
REMOVE 120 VAC POWER FROM THE SYSTEM IF YOU HAVE NOT ALREADY
DONE SO
Refer to Section I.C - Battery Installation for instructions on installing a new battery.
