ARTS Auto Range Transpond System
This system uses DCS signaling to inform you when
you and another
ARTS-equipped station are within
communications range. Both stations must first se-
lect DCS operation using the same DCS code. The
ringer can be activated or not, as desired
Whenever you push the PTT, or every 15 seconds
after ARTS is activated, your radio transmits a
(subaudible) DCS signal for about 1 second. If the
other radio is in range, a beeps sound and their
display shows (in range), or yours does if their
radio polls yours first.
Whether you talk or not, both radios continue polling
each other. If your CW IDer (covered on the next
page) is turned on, your radio IDS in Morse code
every nine minutes. As long as your stations remain
within range, two beeps sound each time a poll is
received (or each time they presses their PTT).
If you move out of range for more than one minute
(four pollings), your radio senses that no signal has
been received, three beeps sound, and
b/inks. If you then move back into range, as soon as
they transmit (or their radio polls) your radio sounds,
and stops blinking
During ARTS operation, your operating frequency is
displayed, but you cannot change it or other settings.
Also, the squelch does not open until a signal is
received for about one second, so remember to
pause before speaking after pressing the PTT.
To use ARTS:
First ensure the battery saver feature is disabled.
Activate DCS (press repeatedly until
appears). Display the DCS tone code (press
and set it to match the other station.
Press (receive-only), (transmit-only),
or just your operating frequency
appears at the left, indicating the current ARTS
mode (described on the next page). Press
again if you want to change it (the operating de-
scriptions assume both radios are set to
Press alone when done. The display returns
to normal, except that now is blinking (indicat-
ing ARTS is enabled, as opposed to regular DCS
operation).
Finally, to activate ARTS, press and then hold
the knob down for second. Two beeps sound,
and your ARTS mode selection appears at the left,
