Operation with a Fist Microphone
Note: When a Distress Call is sent, the unit emits a VERY LOUD
distress alarm tone. To mute the alarm without interrupting the Distress
Call, press the DSC/PRI key on the RAY215 base station. The radio
will remain in DSC mode.
4. The Distress Call is automatically re-transmitted every 3.5 to 4 minutes
as long as you remain in DSC mode. The radio continues to transmit
until either an acknowledge is received or the DSC mode is manually
exited by pressing the 16/9 key. The ACK indicator flashes, indicating
the radio is monitoring for an acknowledge.
5. If a receiving station has Distress acknowledge capability and sends
an acknowledge to you, the DSC tone sounds and the ACK indicator
appears solid for 1 second. Next, the radio exits the DSC mode and
switches to channel 16 for voice communications.

Receiving a Distress Call
When a DSC Distress call is received, the radio automatically enters DSC
mode if you are currently on a selected working channel, in the Monitor
mode, or in the Scan mode. You will not receive a DSC call if the radio is
transmitting or receiving a non-DSC call.
1. When receiving a Distress Call signal, the unit sounds an alarm tone
and enters the DSC mode. A "d" flashes in the small channel display
for Distress.
2. Press the DSC/PRI key. The radio accepts the call, silences the alarm,
and switches to channel 16.
