Operating Instructions

1 Scope of Delivery

Quantity Content

1 Intercom console device with speaker/microphone

1 Intercom mo ile device with speaker/microphone and uilt-in atteries

1 Chargers for uilt-in atteries

1 Power Supply for console device

2 Optical fi er, duplex 62.5 / 125 µm,

ca le length customized (20 m standard)

1 Operating Instructions

X Accessories like ca les, secondary mic unit, external power supplies etc. depending on order

iThe components from mk messtechnik Gm H are matched to each other

and may not e modified and not e applied otherwise

iThe delivery is carried out with fully charged atteries. Due to the self-discharge, the atteries

should e recharged again efore use.

Please read chapter 9, efore recharging attery packs and devices.

2 Fields of application

The Intercom system is used for optical transmission of audio signals (speech).

3 Properties

The system is suited for the undistur ed isolated transmission of audio signals in surroundings with high demands

on electromagnetic compati ility. After applying an optical fi er etween oth devices the system can e used to

communicate etween the a sor er cham er and the control room. The system can e adapted to the application

y adjusting the mic gain and speaker volume independently. The permanent on operation mode allows the user

to talk hands free. Any ongoing transmission can e interrupted y the other station and continues when the

other station stops its transmission (half duplex). An optional external headset connector allows full duplex

communication without acoustic feed ack. Other optional features like line in/out connectors or an additional

external microphone are availa le.
