Model SEH-40
Headphone Instructions
The SEH-40 series of headphones are adjusted at the factory for imme-
diate 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 maximum
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 listening volume with the audio control of either your radio or
intercom 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 manufac-
turers warranty.
Cleaning will help the headphone maintain its “like new” condition
for many years.
WARRANTY
Your headphone is covered by a limited two-year parts and labor
warranty. Please see the enclosed warranty card for details.
You may refer to the parts list on the reverse side, if you choose to
