describe how it functions.

Facilities.

The [FAC]ilities key which can be found on the lower left hand side of the keypad

will have been programmed to control base station facilities. These facilities may be

unique to your service and as such is not possible for us to describe them here. By

way of example, your base stations may consist of a main equipment set, and a

standby equipment set. The standby set can be commanded to take over in the event

of equipment failure by operating the facilities key. When used with a TETRA

channel the Facility key selects either simplex or duplex calls.

Handset

In any mode of operation, picking up the handset will cause the DRC-1 to recognise

and use the handset microphone and ear-piece. For example, a control room

supervisor can pick up the handset and immediately communicate with a mobile

resource the operator is connected with.
