2. How to stop Memory Scan
(1) Auto stop by squelch function:
If the squelch control is rotated clockwise to cut noise before memory
scan starts,
scanning will automatically stop on a memory channel in which a signal has been
received (the squelch has been opened).
When scanning stops, the timer starts. After 15 seconds, scanning will restart. Press the
MEMORY SCAN switch again or press the PROGRAM SCAN to stop scanning.
(2) Stop scanning by use of the MEMORY SCAN switch:
To stop scanning, simply press the MEMORY SCAN (or PROGRAM SCAN) switch
during scan operation.
Note: The frequency of the memory channel where scanning stops will be written
into VFO A or VFO B, depending on the VFO select switch position.
3. To restart Memory Scan operation, press the MEMORY SCAN switch again.
Program Scan
Continuous scanning between frequencies stored in memory channels M1 and M2.
The scan rate is determined by operating mode and TS switch position (100 Hz in SSB and CW
modes, 10 kHz in FM mode, and 1 kHz in any mode when the TS switch is pushed).
Program Scan operation
Performs scanning from high to low frequencies.
1. How to perform Program Scan
(1) Store upper and lower limit frequencies into memory channels M1 and M2.
(2) Press the PROGRAM SCAN switch and its operation will start. Note: Scanning is done
from high frequency to low frequency. If the same frequency is stored іп M1 and M2, the
SCAN indicator on the frequency display flashes but the frequency will not be changed.
2. How to Stop Program Scan
(1) Auto stop squelch circuit:
If the squelch control is rotated clockwise to cut the noise before program scan starts,
scanning will automatically stop at a frequency which has received a signal.
When scanning stops, the timer starts. After 15 seconds, scanning will restart. Press the
PROGRAM SCAN switch or MEMORY SCAN switch to stop scanning.
(2) To stop scanning by PROGRAM SCAN switch:
To stop scanning, press the PROGRAM SCAN (or MEMORY SCAN) switch during scan
operation.
NOTE: The frequency that the scan has been stopped at will be written into VFO A or
VFO B, depending on the VFO select switch position.
If the low end frequency of the band (0.000.0) is stored into M1 or M2 asalower
limit frequency, you can scan the entire band regardless of the frequency in the
other memory channel.
3. Restart Program Scan
To restart Program Scan, press the PROGRAM SCAN switch again. Program scanning will
start at the upper limit frequency.
How to Reset the Timer |
When either Program or Memory Scan operation stops, the timer starts counting. To reset the
timer, press the VFO equalizing switch. The scan operation will start again from the frequency
which the scan has been stopped at.
