This scan operates in memory mode.
E Pre-operation
e Presetting
Program the memory channels before operating a
scan as follows:
Program scan edge frequencies
into scan edge memory channels
P1 and P2. (p. 35)
Program desired scan frequencies
into 2 or more memory channels.
Program desired scan frequencies
with the same operating mode into
2 or more memory channels.
e Scan resume ON/OFF
You can set the scan to resume or cance! when
detecting a signal. Scan resume ON/OFF must be
set before operating a scan. See p. 49 for ON/OFF

the signal condition. when OFF.
Scan stops when detecting a signal.
f you set scan resume to "ON" in set mode
with the [SCAN] switch, the scan pauses for
