2.0 Handheld Battery Installation or Change
The SmaRT handheld unit is powered by three size AAA batteries. When installing bat-
teries, be sure to observe proper polarity as marked on the inside of the compartment to
avoid damaging the unit.
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 6
below.
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 6 below.
3. 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.
