D . Swing the cover up as shown in Figure 10, then pull
free the angled legs at the left and put the cover away.
The inner lid will now be in full view (see Figure 11).

E. Remove the screw that secures the battery compartment
lid (Fig. 11), swing the lid up and pull it away. You have
thus gained access to the battery holder (see Fig. 12).
ATTENTION! Removal of the lid will start a "tamper"
alarm - the trouble indicator will light and both
"memory" and "trouble" will flash in the display
window. If you interrogate the system at this stage by
clicking the <OK> button, "CPU TAMPER ALARM"
and "CPU TAMPER OPEN" will be displayed, in
addition to "CPU LOW BATTERY".

F . Pull the battery holder out and replace all 6 battery cells
- 3 at the top and 3 at the bottom. Make sure that the flat
(negative) end of each cell is pressed against a circular
spring and the capped (positive) end of each cell is
pressed against a flat contact.
CAUTION! If you replace rechargeable cells
with alkaline (dry) cells or vice versa, mount
the battery-type selector in the correct
position (CHRG for rechargeable cells and
DRY for alkaline cells - see Figure 13).

G . Put the battery holder back in, re-mount the battery
compartment lid and re-attach it with the screw. With
correctly inserted fresh batteries and tight closure of the
lid, the TROUBLE indicator should extinguish.
H . Put back the battery area cover - insert the angled legs
at the left edge into their holes and then press the right
edge of the cover against the cabinet surface until the
catches click into place.
I . The "MEMORY" message will continue blinking in the
display (caused by the "tamper" alarm you triggered).
Clear it by arming the system and disarming it as soon
as the exit delay starts.
9.2 Replacing Batteries in Wireless
Devices
The wireless sensors supplied with your system are
powered by high-capacity 3.6-Volt lithium batteries (Tadiran
TL-5902) that last several years, depending on the number
of times the sensor is triggered into transmission.
However, if and when a battery becomes weak, the sensor
itself sends a "low battery" message to the control panel,
and a low battery trouble message is displayed together
with the zone information (see Para. 5.2).
