16 Putting the handset into service

Inserting the dummy plug or connector

Insert the dummy connector (1) / connector with cord (2) into the recess provid-

ed. Make sure the dummy connector is positioned correctly.

If you do not require the man down alarm function on the OpenStage M3 Plus or

OpenStage

M3 Ex Plus you can also use the connector without a cord as a dum-

my connector.

Connecting a corded headset

You can connect a headset with a 2.5 mm jack plug to the left side of your hand-

set.

1. To do this, open the rubber cover using your finger nail and bend it outward.

2. Insert the jack plug into the socket.

The headset volume corresponds to the setting for the earpiece volume

 Page 76.

Use a Bluetooth headset for Ex-proof equipment,  Page 71.

Regardless of whether or not a cord is used, the handset can be placed

with the connector inserted in the charger. Run the cord out from the front

of the charger.
