Figure 5: Communication through Gateways

When the radio connects to a gateway, it plays a tone, displays the Gateway available message,
and shows an appropriate icon. When the radio loses connection with the gateway, it plays a tone,
displays the Gateway not available message, and the gateway icon is blinking.

Gateway and Repeater Synchronization

To communicate via gateways or repeaters, the radio requires synchronization with a gateway or a
repeater.
A gateway or a repeater sends presence signals to radios. If a radio receives presence signals, it stays
synchronized with the gateway or the repeater which sends the signals. If a radio fails to receive a
presence signal it does not immediately lose synchronization. The radio waits for another successful
presence for a time defined by your service provider. This function ensures that calls are not dropped
due to temporary reception issues.
If a gateway or a repeater is unavailable or the radio is not synchronized with a gateway or a repeater,
depending on the setup configured by your service provider, the following scenarios apply:
• The radio falls back to Direct Mode Operation (DMO).
• After pressing the PTT button, a prompt appears warning that the second press overrides the
gateway or repeater operation mode.
• No direct DMO calls are permitted.
In the second scenario, while the radio receives individual calls and group calls, and replying to
individual calls is possible, replying to group calls is not possible.

Transmit Inhibit Mode

The Transmit Inhibit (TXI) Mode is a mode in which the radio sends no radio transmissions. Activate
this mode in RF sensitive areas, for example hospitals, airplanes, where safety can be jeopardized due
to transmission radiation.
To activate, select Menu → More. . . → Networks → TXI Mode → Activate.
In this mode, the radio does not transmit under any circumstances except for the Emergency Calls. All
the functions and keys which cause transmission, for example registration to the network, changing
