4.3 OO-2H02-7588 Handheld Remote Battery Installation
Handheld units are powered by three size AAA batteries. When installing batteries, be sure to
observe proper polarity as marked on the inside of the compartment to avoid damaging the unit.
To replace or install batteries in the handheld:
1. Remove the four small Phillips screws from the Battery Compartment cover and lift the cover
from the handheld.
2. If installing batteries in an empty battery compartment, install three fresh size AAA batteries.
Be sure to position the batteries as shown in Figure 5 below.
3. If replacing expired batteries, remove the old batteries and install three fresh size AAA
batteries. Be sure to position the batteries as shown in Figure 5 below.
4. Replace the compartment cover and tighten the four Phillips screws. These screws should
not be over-tightened, but they should be tight enough to assure the gasket provides a
proper seal.
