Status Information
Status information forms part of the selective calling system. The status of a mobile is
indicated by appending one or more numbers to the mobile’s call- sign. In a similar
way, a control room operative can send a status code to a mobile to command a
required readiness state.
Alpha Tags
Alpha tags are text names, which can be allocated to individual identities, status
codes, and channels. These tags are intended to make the system readily
understandable by translating the numbers used within the system into text. By way of
example the incoming code 12349 can be tagged to display “Dog Van 3 Meal Break”

operator can choose to use the internal loudspeaker, or turn the loudspeaker off by
pressing the [

If the operator is equipped with a headset, then the DRC-32 can also be
interconnected to the telephone system. This interconnection will have been
undertaken by your system supplier. By interconnecting the DRC-32 to the telephone
system, the operator can use the same headset to make and receive telephone and
radio calls. It is also possible to connect a mobile radio conversation directly to the
telephone system – see teleconnect.
Menu System
The menu system provides the operator access to many of the system facilities. The
menu is accessed by pressing the menu key and then using the up and down scroll
keys to move through the menu options. These are described in greater detail later.
Talk Through
Talk through is the term used for a facility which permits one mobile to speak with
another. It would be normal practise for the mobile requiring the talk through facility
to ask control to enable the facility. The DRC-32 can command talk through in several
