sounds with 56 decibels of power.
Protects Hearing using a Sound Activated Compression (SAC)
circuit combined with an ear plug helps protect hearing from loud
sounds such as muzzle blasts. Noise Reduction Rating (NRR) of 29 dB
is among the highest in the industry.
Adjustable Frequency Tuning (AFT) focuses on specic sound
frequencies for crystal-clear reception in any situation.
Weighs less than ¼ oz. and rests comfortably behind either ear,
with or without eyeglasses.

Fitting Instructions
1. Place HD Power
over either ear.
2. Insert earplug into ear by
squeezing and rolling plug
between fingers, it will
compress and gradually
expand after insertion.
Position sound tube in
upward direction so it
extends past the ear hook.
Mark sound tube
approximately 1/8” above
the tip of the ear hook. Cut off excess tube at
mark. Tubing too long will cause the unit to fall
off the ear. Tubing too short will cause the ear
plug to pull out of the ear.
3. While
holding ear
hook
between
thumb and
forefinger,
push the
sound tube
onto the ear
hook; you may need to trim
the tube and repeat this
process to achieve a
comfortable fit.
Turning the Unit On
After inserting the battery, close the battery door completely to turn the unit on. Turn
the unit o by opening the battery door to the rst stop.
Operating the Volume Control
Increase the volume on the HD Power by pressing the top of the volume control toggle.
Decrease the volume by pressing the bottom of the volume control toggle.
Note: The HD Power has a built-in “safety” circuit which limits the output of the instrument to a maximum of 115 dB SPL.
Operating the AFT
The AFT (Adjustable Frequency Tuning) is located directly above the volume control toggle
• Insert the enclosed screwdriver in the bottom center of the AFT pop-up hinged door
• The AFT circuit is the 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 nd the best setting for you, turn the set screw to the desired reception. Dierent
conditions and environments may need dierent settings.
Operating the PBC (Power Boost Control)
• By pressing the PBC button, which is located above the Volume Control Toggle, the user can instantly increase the
power by 6 dB or from 9X to 11X its original amplication.
• To de-activate the Power Boost Control, simply press the PBC button again and you will notice the decrease in amplification.
Complications Which May Arise
If conditions such as irritation, inammation, 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 Power When the HD Power will not be used for an extended period of
time, remove the battery and place the HD Power in its carrying case for storage in a cool, dry
location.
Batteries (Avg. Life 300 Hrs) After extended use of your battery, the HD Power
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 HD Power is not going to be used for a period of days.
If Your HD Power 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.
