CORRECT USE OF THE CARDIOID

HEADBAND 4088

It is important to observe the following

guidelines concerning the daily use of the

microphone.

Correct treatment of the microphone

element

The diaphragm in the microphone element

is the most sensitive part of the unit and as

emphasized earlier, it must be left untouched

to preserve its original characteristics. Do

not spray any substances such as hair spray

directly into the microphone and avoid get-

ting make-up or paint on the microphone

element and housing.

Correct treatment of the microphone

cable

The cable is usually longer than required for

its actual purpose. Ensure that superfluous

cable is wound up in soft loops (preferably

6-8 cm in diameter). Avoid 'kinks' in the

cable. Exposing the cable to stretching

beyond its specifications or stressing it by

winding it tightly over sharp edges will

reduce the microphone's operational life.

Tip: The place where the cable enters

the MicroDot connector will sometimes

be exposed to excessive stress and after

long term heavy-duty use, the cable

might show signs of wear at this point.

As a preventive maintenance procedure,

it may be advisable to replace the con-

nector in this instance. Contact the

nearest DPA Microphones representa-

tive for maintenance advice or assistance.

Correct way to wind up the cable of

the Miniature Microphone. Please note

the slack after the connector.

Correct use of adapters and MicroDot

connectors

To provide users with safe and compact

mounting of connectors, all Miniature

Microphones from DPA are fitted with the

MicroDot connector as standard. A broad

range of connection adapters is offered as

optional accessories for most VHF and UHF

systems for professional use. The adapters

are ultra-compact and will in most cases

take up no more space than the original

connectors.

A connector tightening tool is supplied with

each adapter and should be employed

whenever the MicroDot connector needs

to be tightened safely onto the adapter for

long periods of time. Tighten the MicroDot

until the cable can no longer be turned at

the cable relief. Never attempt to loosen or

tighten the connector by the cable or its

strain relief! Despite the use of Kevlar®, the

cable might be damaged if twisted with

excessive force. Tighten the MicroDot

using finger torque or the recommended

tightening tool only. Do not use glue.

A connector tightening tool is

supplied with each adapter

A connector tightening tool is supplied

with each adapter and is to be turned
