5. MAINTENANCE
5.2 Changing the Transmitter Batteries
The ULD-400-T uses two 1.5 V AAA (LR03) batteries (supplied with ULD-420). To replace the
batteries, follow these steps:
1. Make sure that the Transmitter is turned off.
2. Loosen the battery-door lock with a flat screwdriver.
3. Remove the battery cover.
4. Replace the batteries as shown in Figure 5.2. Observe the battery polarity shown in the
battery compartment.
5. Replace the battery cover to the lock position.
5.3 Cleaning
The only maintenance the ULD-400 requires is inspection and cleaning. Periodically wipe the
exterior with a mild solution of detergent and water. Apply sparingly with a soft cloth and allow to
dry completely before using. Do not use aromatic hydrocarbons, gasoline or chlorinated solvents
for cleaning.
