ADVANCED OPERATION (AMATEUR RADIO BAND)

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 matching CTCSS tone. This can help keep your radio quiet until a specific call is received, which may be helpful while operating in congested areas.

rWhen 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.

rPress the key to enable the adjustment of the CTCSS frequency.

rRotate 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).

rWhen 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.
