Battery installation and type:
We highly recommend using high quality alkaline battery, Energizer max or Duracell
Coppertop are recommended. To install battery, remove one set screw and pivot door
open by loosening other screw. Hold amp upside down, tap lightly and battery holder
should pop out. If it does not come out easily, grab with fingers and edge it out, being
careful not to pull too hard on two wire leads which attach battery compartment to amp.
Using a flat head screwdriver, pop batteries out of holder and replace properly as
marked. Gentry push battery compartment back into amp, DO NOT FORCE IT. Pivot
battery door closed and retighten screws.
Power ON/OFF, LED display:
Power ON & OFF is a simple toggle switch. Up is power on, down is power off. The
LED will light up when amp is turned on and will flash when battery power is low.
When battery power is very low light will go off, however amp will work. At this point,
battery must be replaced as soon as possible.
Mute button makes it easy to go from on location to another without having to adjust
volume or meter null. By placing the mute toggle switch in the up position, all sound
will be muted out, until it is switched off (put in the down position).
Meter Null / Sensitivity / Meter
Meter null is an adjustment knob which is used to get a baseline for background noise.
In order to use properly, with the sensitivity switch down, choose the listening devise,
start listening and watch the meter to see if there is any background noise. A 100
reading indicates that what you're hearing is inundated with background noise, or you're
hovering over the leak itself. Starting with the meter null notch facing up, turn the null
to the left to establish a noise baseline (low). You can then turn the meter to the right to
