CONTROL PANEL
1. TUNER/BATT TEST CONTROL: Tunes the detector
to its maximum sensitivity by adjusting the
“threshold level” to a faint tone. Also, when
turned to BATT TEST position, signals condition of
batteries with audio tone and LCD bar graph.
2. Liquid Crystal Display: LCD gives a continuous,
visual check of battery condition and provides a
visual display of signal strength. A bar graph rises
with an increase in signal strength and falls with a
decrease in signal strength. The bar graph also
indicates the approximate strength of the
batteries when the tuner is in the BATT TEST
position. A full-scale reading of the bar indicates
fully charged batteries, while just a few bars
means the batteries are getting low. And when
there’s only a couple or no bars remaining, it’s
time to replace the batteries. Also, at this point,
“BATT OK” is replaced by a flashing “LO BATT.”
NOTE: Always remove your headphones or turn
down the volume before clicking into the BATT
TEST position.
3. Light Emitting Diode: LED flashes red when a
target is detected or the batteries are being
tested.
4. VOLUME CONTROL: Adjusts volume of audio
headphone signal. The OFF position turns
detector off.
5. STEM MOUNT: Bottom of control housing slides
into mount on stem handle, providing easy
detachment of the control housing for hip-
mounting.
