WEARING THE SPH10

Microphone Installation

Two microphones are included in the package: a long-boom microphone for high noise

environment and a short microphone for indoor use.

Plug the microphone into the microphone port and turn clockwise until tightened. Adjust the

direction of the long-boom microphone so that the triangular mark on the microphone is

pointing towards your mouth.

Since SPH10 is mostly exposed on external environment where noise prevails, microphone

can be selected according to the noise level. For the highly noisy environment, boom-

microphone is recommended allowing microphone to stay near user’s mouth. For the less-

noisy environment, pin-type microphone is recommended to provide short-length one allowing

users to move freely.

Using Chin Strap

You can use the chin strap to tighten the headset.
