INSTRUCTION MANUAL
The MC-30S (MC-35S) is a hand held dynamic microphone
specifically developed for transceiver operation.
FEATURES
1. Close talk capability
A selector switch is provided to permit normal or close
talk operation.
The close talk feature assures noise-free transmission
and improved signal intelligibility.
N
Excellent tone quality
Each microphone is factory tested to ensure maximum
performance superb tone quality both in normal and
close talk operation.
3. Easy operation and high reliability
Based on human engineering technology, the micro-
phone is designed for easy and fatigueless operation.
The selector slide and PTT micro-switch contribute to
the easy operation and high reliability of the micro-
phone.
Both a microphone hook and hanger are provided.

CAUTION
1. For close talk operation, read this instruction manual
carefully.
2. The microphone has precision parts. Do not open the
case or substitute any parts.
3. Handle the microphone with reasonable care. Do not
subject to excessive mechanical shock.
OPERATING GUIDE
Use the MC-30S with a low input impedance (5002)
transceiver, and the MC-35S with a high input impedance
(50k ) transceiver.
1. General operation
NORMAL: Omnidirectional use as a handy microphone
during quiet mobile or fixed station opera-
tion.
NOISE CANCELLING: Bi-directional use in high am-
bient noise environments, such as mobile
operation when driving with windows
opened.
2. Close talk operation

3. Microphone position for
close talk operation.
For best results, hold the
microphone about 2 ~ 4cm
from your mouth. Do not
cover the hole at the rear of
the microphone, as it will
reduce noise cancelling ef-
fectiveness.

Operating Guide

General Operation

Use as omnidirectional (NORMAL) for quiet locations or bi-directional (NOISE CANCELLING) in noisy environments.

Close Talk Operation

Set selector switch to NOISE CANCELLING for noisy environments; NORMAL for quiet locations.

Microphone Position for Close Talk
