14.0 MAINTENANCE INFORMATION

THE ALLEGIANT SYSTEM IS DESIGNED TO

PERFORM FOR LONG PERIODS OF TIME

WITH LITTLE OR NO MAINTENANCE.

OCCASIONALLY, KEYBOARD CLEANING

OR CPU BATTERY REPLACEMENT MAY

BE NECESSARY. INSTRUCTIONS ARE

PROVIDED IN THIS SECTION.

14.1 Cleaning the Keyboard

The keyboard may be cleaned when necessary, by

temporarily removing it from the system and wiping it

with a damp cloth. If a conventional spray cleaner is

required, spray the cloth first, then wipe off the surfaces.

Do not use petroleum-based cleaners or those containing

benzene, triclorethylene, ammonia or acetone, which

could damage plastic surfaces.

14.2 Replacement of Memory Backup

Batteries

The circuit board’s lithium batteries only require attention

when replacement is necessary. The batteries enable

RAM memory to retain its contents for up to a year

without the unit being powered. Since these batteries are

not used while the AC power is on, several years of

service should be expected before replacing them is

necessary.

When the batteries have reached the end of their useful

life, the Time and Date portion of on-screen monitor

displays alternate with ?? ?? ??. This display informs the

user that the CPU batteries must be replaced. The front

panel of the unit must also provides LED indication of a

low battery condition.

The memory backup batteries are located on the CPU

module. Refer to the INSTALLATION PROCEDURE,

Section 6 for information on removing the unit cover to

access the CPU module.

The two batteries are mounted on the left edge of the

circuit board. Insert a small flat-blade screwdriver into the

slot on one of the battery holder sockets and gently pry

the battery from the holder until it can be removed by

your fingers. Replace the old battery with the new battery

by lifting the retaining clip up while inserting the battery

into the socket. Ensure that the negative side of the

battery contacts the socket by seating the battery until it is

somewhat flush with the battery holder. Repeat this

procedure for the other battery.

Reprogramming of the system’s time and date and

sequences must now be reentered. Other system-

programmed data (camera titles, alarm configurations,

user lockout data etc.), are stored in nonvolatile memory,

and should be unaffected.
