Installing the Battery
Remove sticker from battery. To insert battery, open battery compartment by pulling down
on the rim of the compartment door. The battery is held in place by a small lip on the
bottom of the compartment. Place the battery into the compartment so that the (+) sign
side of the battery is facing up; when the battery is inserted correctly, compartment door
will close with ease. A #13 Mercury or Zinc Air battery is recommended.
With the unit facing this direction, the “+” sign on the battery goes the opposite the lip on
the batter compartment door. Also, inside the unit is a red dot identifying the “+” side.
NOTE:
A weak battery may cause the unit to buzz or hum.

Turning the Unit On / Off
After inserting the battery, close the door completely to turn the unit on. Turn the unit off
by opening the battery door to the first stop (click).
Operating the Volume Control
Increase the volume on the HD Pro Elite by pressing the top of the Volume Control toggle.
Decrease the volume by pressing the bottom of the Volume Control toggle.
NOTE
:
The HD
Pro Elite has a built-‐in “safety” circuit which limits the output of the instrument to a
maximum of 115dB SPL.
•
Once the battery door is completely shut, you will hear the unit turn on by 4 upscale
tones. (The unit has 19 levels of volume.)
•
Each time you press the Volume Control toggle either higher or lower, you will hear a
single tone.
•
Once you’ve reached either the maximum or minimum limit, you will hear a double
tone.
•
Adjust the volume to a comfortable listening level.
Operating the AFT
The AFT (Adjustable Frequency Tuning) is located directly above the volume control toggle
switch.
•
Insert the enclosed screwdriver in the bottom center of the
ADT pop-‐up hinged door.
•
The AFT circuit is a set screw marked NH (Normal – High).
•
With the AFT set screw in the 7:00 position the emphasis is on
the lower end of the high frequencies. By turning the AFT set
screw to the right (clockwise) you are changing the emphasis
to the higher frequencies, with the maximum setting at the
5:00 position.
To find the best setting for you, turn the set screw to the desired reception. Different
conditions and environments may need different settings.
Complications Which May Arise
If conditions such as irritation, inflammation and pain arise, they are normally due to
pressure applied from the ear plug on a particularly sensitive area of your ear. You may
easily be able to correct this by trimming the ear plug at the point of irritation. For an
actual allergic reaction, or any other unusual conditions, consult your physician.
Storing the HD Pro Elite:
When the unit won’t be used for an extended period of time,
remove the battery and place the unit in it’s carrying case for storage in a cool, dry location.
Batteries (Avg. Life 360 Hrs):
After extended use of your battery, the unit sound volume
will rapidly get weaker, and may become noisy and ineffective in operation. This indicates
that the battery should be replaced. Always remove the battery if your unit is not going to
be used for a period of days.
If Your HD Pro Elite Whistles:
Whistling/squealing may sometimes occur as you cup your
hand over your ear and adjust the volume control. This action directs sound leaking from
the ear plug into the microphone, resulting in a whistle. This should disappear when you
take your hand away. If not, check to make sure the ear plug is inserted properly.
