The FT-250R 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 scanning
after it halts on a signal.
Setting the Scan Resume Technique
Three options for the Scan-Resume mode are available:
5 SEC 5 SEC
5 SEC 5 SEC
5 SEC
: In this mode, the scanner will halt on a signal it encounters, and will hold there for
5 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.
BUSY BUSY BUSY BUSY 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.
HOLD HOLD
HOLD HOLD
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.
