which is frequently changing, including time/date and system crosspoint data (i.e.,
which camera is currently being displayed on which monitor). More vital system
data such as camera titles, alarm settings, user information and passwords, etc. is
stored in non-volatile memory that is not affected by the condition of the batteries
or the main AC power.
Remove the front panel of the main CPU bay by loosening the four fasteners. The
two batteries are mounted on the front edge of the CPU card and are about 25 mm
(1 in.) in diameter. 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 old battery with new battery by lifting the retain-
ing clip up while inserting the battery into the socket. Insure that the negative side
of the battery contacts the socket by seating the battery until it is somewhat flush
with the level of the battery holder. Repeat procedure for other battery.
Verification of the system's time and date and sequence programming should be
made to insure no information was lost. Refer to the appropriate section of the
instruction manual if any reprogramming is required.
