Magnum Ear Hearing Aid Operation Manual - page 2
The Magnum Ear Canal
features a volume control
and two response
adjustments. It utilizes a
soft sponge tip which needs
to be threaded onto the
unit prior to being worn.
Once you have done this,
compress the soft tip and
insert it into your ear canal
as shown.
Regardless of the volume
setting, it will automatically
limit your exposure to the
muzzle blast.
Magnum Ear products are designed to run on hearing aid
batteries. Size 13 has an orange sticker, and the size 312
sticker is brown. The battery turns on when you remove
the sticker. Battery life will exceed 150 hours of continuous
use with a size 312 and over 300 with a size 13. Left
unused, the battery will eventually run down after a few
months. This is normal for zinc air batteries.
Use the cleaning brush and/or a
soft, dry cloth to remove earwax
or other particles that may
accumulate around the canal,
volume control, and battery
compartment; never use water,
solvents, cleaning fluids or oil to
clean your Magnum Ear.

Improper fit of this device will reduce its effectiveness in attenuating
noise. Consult the enclosed instructions for proper fit.
Although hearing protectors can be recommended for protection
against the harmful effects of impulsive noise, the Noise Reduction
Rating (NRR) is based on the attenuation of continuous noise and
may not be an accurate indicator of the protection attainable
against impulsive noise such as gunfire.
The level of noise entering a person’s ear, when a hearing protector
is worn as directed, is closely approximated by the difference
between the Aweighted environmental noise level and the NRR.
eXample:
1. The environmental noise level as measured at the ear is 92
decibels dB(A).
2. The NRR is 29 decibels (dB).
3. The level of the noise entering the ear is approximately 63 dB(A).
Caution: For noise environments dominated by frequencies below
500Hz, the Cweighted environmental noise level should be used.
