Capacity Max

Capacity Max is MOTOTRBO control channel based

trunked radio system.

MOTOTRBO digital radio products are marketed by

Motorola Solutions primarily to business and industrial

users. MOTOTRBO uses the European

Telecommunications Standards Institute (ETSI) Digital

Mobile Radio (DMR) standard, that is, two-slot Time

Division Multiple Access (TDMA), to pack simultaneous

voice or data in a 12.5 kHz channel (6.25 kHz equivalent).

4.1

Push-To-Talk (PTT) Button

The PTT button serves two basic purposes.

• While a call is in progress, the PTT button allows the

radio to transmit to other radios in the call. The

microphone is activated when the PTT button is

pressed.

• While a call is not in progress, the PTT button is used to

make a new call.

Press and hold the PTT button to talk. Release the PTT

button to listen.

If the Talk Permit Tone or the PTT Sidetone is enabled,

wait until the short alert tone ends before talking.

If the Channel Free Indication feature is enabled on your

radio (programmed by your dealer), you will hear a short

alert tone the moment the target radio (the radio that is

receiving your call) releases the PTT button, indicating the

channel is free for you to respond.

You hear a continuous Talk Prohibit Tone if your call is

interrupted, for example when the radio receives an

Emergency call. You should release the PTT button.

4.2

Programmable Buttons

Depending on the duration of a button press, your dealer

can program the programmable buttons as shortcuts to

radio functions.

Short press

Pressing and releasing rapidly.
