1. Turn the transmitter on by pulling the PUSH/PULL POWER SWITCH and place the transmitter
on the ground. If the batteries are working, the battery lamp will blink.
2. Turn the receiver ON (if the batteries are working, the meter will move to the BATT section of
the meter) and set to the Active/Norm Mode.
3. Set the SENSITIVITY knob to the “SET” line.
4. Hold the receiver in a position parallel to the transmitter. The meter needle should move all the
way to the right side of the meter, and the audio tone should be loud.
5. Move away from the transmitter, holding the receiver in the same parallel position. At 10-20ft
the signal level should start to drop - the meter needle will move to the left and the audio tone
will begin to fade.
6. Turn the receiver perpendicular to the transmitter - both the meter reading and the audio tone
should suddenly drop.
If either the receiver or the transmitter does not respond to the above tests, check the batteries.
Refer to Section 7, Maintenance for instructions.
