Model SEH-2
Headphone Instructions
The SEH-2 series of headphones are adjusted at the factory for immedi-
ate 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 mini-
mum 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 head-
band 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 lis-
tening 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
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.
