Battery Installation Procedures:
1. Use a Phillips head screwdriver to carefully loosen the two battery
compartment screws in the battery compartment door on the back
(bottom) of the Handset (Figure 1, pg. 13).
2. Insert two AAA alkaline batteries inside the battery compartment as shown
below (Figure 2, pg. 13).
3. Follow the “+/-” signs on the label inside the battery compartment for
proper battery installation.
4. Insert the negative end of the battery into the compartment first by
pushing it against the spring. Then lower the positive end into the slot.
NOTICE
DO NOT
unscrew or remove the two top small screws on the
back of the Handset (See Figure 1, pg. 13). This may cause
severe damage to the Handset, causing it to not work when you
need to use it during an emergency.
NOTICE
DO NOT overtighten the battery compartment screws.
Overtightening the battery compartment screws may cause severe
damage to the Handset.
5. Replace the battery compartment door and carefully tighten the battery
