Section 2 Operation (Continued)

2.2 Optional EnviroMic (Continued)

When a cochlear speech processor is used, the PR-216 receiver and M-216

transmitter take the place of the cord-type auxiliary microphone of the

processor.

COMTEK provides an assortment of direct audio-input cords for hearing

aids and cochlear speech processors. An audiologist should be consulted

when direct audio input cords are used.

Operating EnviroMic:

The PR-216’s EnviroMic gain is nominally set at the factory to a suitable

level. However, if a gain adjustment is necessary, the following procedure

should be used:

a. With the small screwdriver provided, turn the input gain control fully

counterclockwise.

b. Set the volume control on the PR-216 for a normal listening level with

headphones or hearing aids when the wireless microphone transmitter

is being used.

c. Slowly turn input gain control clockwise until your own voice level

matches the voice level of the speaker using the wireless microphone

transmitter. If a higher EnviroMic sensitivity level is required, additional

gain can be used, but only up to the threshold of feedback.

Note: Higher gain settings will bring up the voice signal as well as the

background noise. Higher gain settings should only be used in a low noise

environment.
