Band Scanning
Band scanning rapidly checks every frequency within your DX15's
operating range of 118.000 MHz through 136.975 MHz sequentially. In
Band Scanning mode, the DX15 will pause on frequencies that have a
strong enough signal to break squelch so that they can be heard.
To enter Band Scanning mode:
 Exit any other mode by pushing the CLR button on the keypad.
 Adjust Squelch (see section Setting Squelch for details) so that the
speaker is quiet. If a signal is received during scanning the scanning
will pause, allowing you to listen to the received signal. When band
scanning your DX15 may receive a variety of signals at widely‐varying
signal strengths. Setting Squelch too high will allow only the very
strongest signals to be heard. Setting Squelch too low will result in the
scan being stopped frequently, often on noisy frequencies that cannot
be understood. Thus, setting Squelch properly for band scanning will
necessarily be a compromise.
 To scan up push and hold (for at least 1 second) the ► button. To scan
down push and hold the ◄ button.
During Band Scanning (or any of the other scan operations ‐ see section
Memory Scanning and Last Ten Frequencies Scanning for details), the
decimal point between the digits flashes to indicate that a scanning mode
is active.
When a signal is received that exceeds the Squelch setting, Scan mode
will pause for as long as the signal is being received. Scanning will resume
a few seconds after the last signal is received. To force the radio to
continue scanning while Band Scanning has paused on a frequency, press
either the ◄ or ► button to "nudge" Band Scanning to continue its scan.
