TRANSMITTER OPERATION
FM TRANSMISSION
ARTS™ Operation
The ARTS™ system uses DCS signaling to inform you when you and another ARTS™
equipped station are within communications range. This can be especially valuable during
search-and-rescue operations, as a base station can quickly use ARTS™ to alert a field unit
that it is out of range; the field unit can then move to a better location to re-establish commu-
nications.
ARTS™ is easy to use:
1. Press the
[
FUNC
]
key momentarily, then rotate the SELECT knob, as needed, until
Multi Function Row “f”
[
ARTS, SRCH, PMS
]
appears on the display.
2. Press the
[
A
](
ARTS
)
key to activate ARTS™ operation.
3. Your display will change to “out range” to indicate the
beginning of ARTS™ operation. Every 30 seconds, your
radio will transmit a “polling” call to the other station.
When that station responds with its return ARTS™ poll-
ing signal, your display will change to “in range” to con-
firm reception of the response.
4. To cancel ARTS™ operation, press the
[
A
](
ARTS
)
key again (the “out range” or “in
range” indication will disappear from the LCD).
ARTS™ Alert Beep Options
The ARTS™ feature allows two kinds of alert beeps (with the additional option of turning
them off), so as to alert you to the current status of ARTS™ operation. Depending on your
location and the potential annoyance associated with frequent beeps, you may choose the
Beep mode which best suits your needs. The choices are:
RANGE: The beeps are issued only when the radio first confirms that you are within range,
but does not re-confirm with beeps thereafter.
ALL: Every time a polling transmission is received from the other station, the alert beeps
will be heard.
OFF: No alert beeps will be heard; you must look at the display to confirm current ARTS™
status.
To set the ARTS™ Beep mode:
1. While still in Multi Function Row “f”
[
ARTS, SRCH, PMS
]
, press and hold in the
[
A
](
ARTS
)
key for one second. This is a “hot key” which will instantly recall Menu
Mode No-008
[
ARTS BEEP
]
.
2. Rotate the DIAL to select the desired ARTS™ Beep mode (see above).
3. When you have made your selection, press and hold in the
[
FUNC
]
key for one second
to save the new setting and exit to normal operation.
