The
FT-252
allows you to scan just the memory channels, the entire operating band,
or a portion of that band. It will halt on signals encountered, so you can talk to the
station(s) on that frequency, if you like.
Scanning operation is basically the same in each of the above modes. Before you begin,
take a moment to select the way in which you would like the scanner to resume scan
-
ning after it halts on a signal.
Setting the Scan-Resume Technique
Three options for the Scan-Resume mode are available:
BUSY
: In this mode, the scanner will halt on a signal it encounters. Two seconds after
the carrier has dropped because the other station(s) ceased transmission, the
scanner will resume. In the case of constant-carrier signals like Weather Station
broadcasts, the scanner will likely remain on this frequency indefinitely.
HOLD
: In this mode, the scanner will halt on a signal it encounters. It will not restart
automatically; you must manually re-initiate scanning if you wish to resume.
TIME
: In this mode, the scanner will halt on a signal it encounters, and will hold there
for five seconds. If you do not take action to disable the scanner within that time
period, the scanner will resume even if the stations are still active.

1. Press the
