Note:
if Page or Tone Alert is ON, Scan will not function.
For CTCSS operation, Scan stops and the squelch opens
only for signals that contain the same CTCSS tone that is
stored in your transceiver.
For DTSS operation, Scan stops for any signal received;
however, the squelch opens only for signals that contain
the same DTSS code that is stored in your transceiver.
When both CTCSS and DTSS are ON, Scan stops for
signals that contain the matching CTCSS tone. However,
the sque/ch opens only when the matching DTSS code ts
received.
