Terminal Maintenance
Figure 11-3. Battery Support Location
The battery is located above the terminal's rear panel (figure 11-3). To replace the battery,
perform the following procedure:
Step
1. If terminal power is off, turn it on and wait until the terminal is ready for use. (The
terminal now supplies power to non-volatile memory. This "protects" the configura-
tion menus while you replace the battery.)
Step 2. Refer to figure 11-4. Squeeze the tabs toward the center of the battery support with
enough pressure to disengage the flanges which hold the battery support in place.
Pulling down frees the battery support from the terminal.
Step 3. Remove the old battery from the support.
Step 4.
Insert the new battery into the support. Be sure the positive end of the battery
corresponds to the positive end of the support (+ to + and - to -).
Step 5. Insert the battery support into the terminal. A slotted guide in the outward-facing
side of the support ensures that you replace the battery support with the correct
polarity.
