VFO FULL RANGE SCAN
This is to scan the entire band between 144.000MHz and 145.995MHz. (IC-25A : between
143.800M Hz and 148.195MHz.) |
1. Set the VFO/MEMORY CHANNEL Switch to VFO position, and the VFO-SCAN FUNCTION
Switch to "FULL-S" position. Depressing the S/S button starts the scan from the VFO
frequency to the low edge.
The scanning frequency increments depend on the VFO Switch
setting.
2. When the scanning frequency reaches the low edge, it automatically returns to the high edge
and continues scanning down to provide endless scanning operation.
3. Other operations are the same as the PROGRAMMED SCAN and MEMORY SCAN.
The scanning speed can be adjusted by the SCAN SPEED Control located under the top cover.
Rotating the control counterclockwise makes the scanning speed faster. |
While the SCAN is operating even if the SCAN stops оп a frequency, the decimal point of the
frequency display will blink according to the scanning speed.
RESUMING SCAN
All scan modes are provided with the resume scan function. When the scan has been stopped by
the auto-stop function, the scan will restart after the cause goes away, or after passing а specified
time.
