Controller - Low Battery alarm appears (on the AUI, controller UI or via remote digital output).
Chemical leakage from an old battery can cause damage.

Perform the following steps to replace the battery:
1. Remove the upper, rear filter panel by loosening the 12 quarter-turn fasteners securing the panel to
the transmitter.
2. Replace the battery in the 3V BATTERY holder on the rear of the controller assembly (see
Figure 3.3.3 on page 3.3.8 ).
3. Re-install the upper, rear filter panel removed in Step 1 .
4. Check for any alarms on the AUI (local or remote) or controller UI (see “Viewing Transmitter Status -
