occasionally cause “TSQ” to appear. When “TSQ” ap-
pears, this means that the Tone SQuelch system is ac-
tive, which mutes your VXA-700’s receiver until it
receives a call from another radio sending out a match-
ing CTCSS tone. This can help keep your radio quiet
until a specific call is received, which may be helpful
while operating in congested areas.
r When you have made your selection of the CTCSS
tone mode, press the key momentarily, then ro-
tate the DIAL selector knob one click clockwise to
select Menu Item (TONE Set). This Menu selection
allows setting of the CTCSS tone frequency to be used.
r Press the key to enable the adjustment of the
CTCSS frequency.
r Rotate the DIAL selector knob until the display indi-
cates the Tone Frequency you need to be using (ask
the repeater owner/operator if you don’t know the tone
frequency).
r When you have made your selection, press the
key to save the new setting, then press the PTT key
repetitively until the radio exits to normal operation.
Note: Your repeater may or may not re-transmit a
CTCSS tone - some systems just use CTCSS to con-
trol access to the repeater, but don’t pass it along when
transmitting. If the S-Meter deflects, but the VXA-700
is not passing audio, repeat steps “1” through “3”
above, but rotate the DIAL selector knob so that “SQL”
disappears - this will allow you to hear all traffic on
the channel being received.
