Instruction manual

Step 4
Attach a 9V battery to the battery snap and place it into the case. Snap the battery cover into the back
case as shown in Figure 19.
Step 5
Place the unit onto a table and turn it on. Move to one side of the detector so that you are out of the field
of view of the detector. Walk in front of the detector and a tone will sound from the speaker. The unit is
now ready for use.
Note: When the switch is in the OFF position, it disconnects the voltage to the sound generator IC only.
The rest of the circuit is still operating. The battery will run down if it is left in the OFF position. To
increase battery life, remove the battery if you intend to leave the unit in the OFF position for long periods
of time.
INSTALLATION
The detector can be either placed on a flat surface or mounted onto a wall. Adjust the angle lever to
the open position (see Figure 20). Align the two taps on the bracket with the two grooves on the case.
Adjust for the desired angle and move the angle lever to the lock position.
