Headphone Instructions
The SEH-40 series of headphones are adjusted at the factory for
immediate use with all Sigtronics emergency apparatus intercoms
and radio adapters in emergency vehicles. The headphone is
equipped with a single plug and a coiled cord.
The headband is adjustable through a full range of motion, and the
locking nuts may be tightened to allow you to custom fit the head-
phone. Place the headphone over your head and adjust the slides
up until minimum pressure is felt on the top of your head. For max-
imum noise attenuation, the clamping pressure of the headband
has been set at the factory. Releasing the clamping pressure by
bending the headband is not advised, because loss of attenuation
will result.
When you first connect the headphone, turn the volume control on
the headphone up to the full clockwise position, then adjust the lis-
tening volume with the audio control of either your radio or inter-
com as appropriate. If applicable, crew members should also turn
their individual headphone volumes up fully. Doing this allows for
a full range of adjustment for each passenger, since those with the
most acute hearing can turn their headphone volume down, if
necessary.

The headphone parts may be cleaned with mild soap and water
using a soft cloth. Then dry immediately. Caution: Do Not immerse
any part of the headphone in water or any other liquid. Exposure to
moisture may cause internal corrosion and failure and will void your
manufacturers warranty.
Cleaning will help the headphone maintain its “like new” condition
for many years.
