Start with the controls set as shown in the photo below:

Mode in the OFF position

TUNE SPEED in the ALL MET FAST position

2.

DISC LEVEL at MIN

Perform Audio Battery Test

Turn the Mode Switch from OFF to NORM (if you are doing
this test for the Salt Mode, switch from OFF past NORM and
directly into SALT). This will turn on the detector and will give
you a number of beeps. If the batteries are fully charged, you
will hear 6 or 7 beeps. As the batteries drain, you will hear fewer
and fewer beeps. When you hear one or two beeps, it will be
time to replace your batteries.

After the beeps are done, you will hear a slight humming sound. 
This is the threshold tone. Its purpose is to give you a reference
point to judge targets by. Some targets may be small enough or deep enough that they will not be able to
generate an audio signal by themselves. By monitoring a threshold, you already have a signal so changes
in that signal will be easier to hear. However, if the threshold is set too loud or too soft, small changes in
the signal will be hard to hear. We will be talking about changing the threshold tone a little later.

Set Ground Adjust

We will now set the GROUND ADJUST for the air test. This method is only for the Quickstart tests. See
the section 

"Ground Balancing Your Tiger Shark" 

for the correct procedure for ground balancing

your Tiger Shark in the field. Please note that the NORM and the SALT Modes work at different ends of
the GROUND ADJUST knob.

Ground balance for the NORM Mode: Turn your GROUND ADJUST knob clockwise or towards the
positive side for 5 full turns. This will take you past the end range of the GROUND ADJUST
potentiometer. The knob has no end stops, but you may notice a very slight increase in the drag of the
knob as it passes the 3 and 3/4 mark. By turning the knob 5 full turns clockwise, we are assured that the
GROUND ADJUST is in the very farthest positive position. Once you are at the positive position, turn
