Hand Held Device 
The Hand Held Device (HHD) is a small pocket size unit con-
taining the test activation transmitter and the ingress test signal 
receiver. 
 
 
Battery Installation 
The HHD is powered by three standard AAA alkaline batteries. 
To install the batteries, loosen the battery compartment screw 
and remove the cover. Install the batteries, all three with the 
positive end in the same direction, as indicated. Replace the 
cover and tighten the screw. Use care not to over tighten the 
screw. 
 
Be sure to recycle or properly dispose of old batteries. 
 
The HHD automatically powers off when the battery condition 
is low to protect the batteries from excessive discharge and 
possible leakage. Periodically remove the battery cover and 
inspect the batteries for signs of leakage. 
 
Caution: Do not store the HHD for extended periods of time 
with the batteries installed. Failures due to battery leakage are 
not covered under warranty.
