Headphone Instructions
The SEH-2 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 head strap is adjustable so you may custom t the headphone. Place
the headphone over your head and adjust the strap until minimum pres-
sure 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 rst 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 appro-
priate. If applicable, crew members should also turn their individual head-
phone 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.
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 replace
parts yourself. The parts list describes parts for this particular headphone
only. Parts lists for other models are available on our Web Site or can be
obtained by contacting Sigtronics Corporation.
