Model SH-40

Headphone Instructions

The SH-40 series headphones are adjusted at the factory for immediate use with

all current standard radio systems in general aviation aircraft. SH-40 headphones

are equipped with one plug in the standard conﬁguration. The headphone plug

is a large diameter plug and should be inserted into the headphone jack (.250”

standard monaural jack).

The headband is adjustable through a full range of motion, or the locking nuts

may be tightened to allow you to custom ﬁt the headphone. Place the head-

phone over your head, adjust the slides up until minimum pressure is felt on

the top of your head. The headphone is now properly adjusted. For maximum

noise attenuation, the clamping pressure has been set at the factory. Releasing

the clamping pressure by bending the headband is not advised, because loss of

attenuation will result. Note: If especially small (children) or large headbands are

needed, they may be ordered from Sigtronics.

When you ﬁrst connect the headphone, turn the volume control on the head-

phone up to the full clockwise position, then adjust the listening volume with the

audio control of either your radio or intercom as appropriate. Passengers 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 head-

phone in water or any other liquid. Exposure to moisture may cause internal cor-

rosion 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 three-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 contact-

ing Sigtronics Corporation.
