1. Place HD 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 by pressing the top of the volume control toggle.
Decrease the volume by pressing the bottom of the volume control toggle.
Note: The HD has a built-in “safety” circuit which limits the output of the instrument to a maximum of 115 dB SPL.
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 When the HD will not be used for an extended period of time, remove
the battery and place the HD in its carrying case for storage in a cool, dry location.
Batteries (Avg. Life 300 Hrs) After extended use of your battery, the HD 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 is
not going to be used for a period of days.
If Your HD 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.
