ITU channels:
To select the scan group (band or channel), shift the cursor to either the position of the band or
channel number by pressing the [2] CURS key. (Band scan is useful to watch frequencies on the
same channel in different bands.)
2. Press the [6] SCAN key, and “SCAN” appears. The receiver starts scanning, stopping at a
channel where the signal is stronger than the scan-stop level. The receiver will restart
scanning when the traffic goes out of that channel.
For example, the scan group is “channel” and scan starts at ITU 1203:
R
0 2 4 6 8 10 S
LOW
J3E
AGC NB SWEEP SCAN
SIMP
3. To stop scanning, press the [6] SCAN key. “SCAN” disappears from the operation display.
1.12 Frequency Sweep
Sweep is the function where the receiver searches for a signal within a selected frequency
coverage. For sweep operation, the AGC function should be ON.
The defaults of respective parameters are as follows:
Sweep stop signal level 3
Sweep stop time 2 s
Sweep width 100 kHz
Step frequency 1 kHz
These can be adjusted on system codes 9951 through 9954.
NOTE: Sweep width is the frequency width to sweep on both sides of the selected frequency.
Sweep step is the frequency interval at which the receiver sweeps the sweep width.
Procedure
1. Select the sweep center by key operation.
2. Press the [6] SCAN key. “SWEEP” appears and the receiver starts sweeping.
3. To stop sweeping, press the [6].
