allows configuration of the unit as a master or slave unit. The unit is configured as a master
when the switch is in the

Cover Installation
1.
Inspect and clean the machined flange flame joint surfaces of both the cover and box.
Surfaces must be smooth, free of nicks, scratches, dirt, or any foreign particle build-up that may
prevent a proper seal. Surfaces must seat fully against each other to provide a proper explosion-proof
joint.
2.
Clean the surfaces by wiping them with a clean lint-free cloth.
3.
Install all 12 cover bolts.
Use only the bolts supplied with the enclosure. Do not omit any bolts.
4.
Torque the cover bolts to 17 ft∙lb (23 N∙m).
Operation
The station has an on-off/volume control switch and a push-to-talk switch.
1.
Turn the unit on or off and adjust the volume level in the listen mode using the on-off/volume control
switch.
2.
Turn the unit off by turning the switch completely counterclockwise.
3.
Adjust the switch completely clockwise for maximum volume.
The push-to-talk switch controls the audio communication between stations.
1.
Press the push-to-talk switch to send a message to another station.
2.
Release the push-to talk switch to put the station in listen mode so that the station receives messages
from other stations.
The push-to-talk switch is not functional when the station is configured as a slave station.
