MEMORY SCAN

Memory Scan scans all memory channels containing data (All-channel Scan) or only a group of channels specified by you (Group Scan). This type of scan always ascends up through the channel numbers; the direction of scan cannot be changed. While scanning, if you want to skip over some programmed channels, turn the M.CH/VFO.CH control. Pressing Mic [UP] or [DWN] will also skip over channels but only during All-channel Scan.

All-channel Scan or Group Scan can be selected via Menu No. 66 (GRP.SCAN). The default is All-channel Scan (OFF).

The following are additional important points regarding the Memory Scan function:

¥Starting a transmission by closing the CW key, by sending a packet, or by triggering the VOX circuit by voice or the DRU-3 Digital Recording Unit stops Memory Scan; however, transmission does not begin immediately.

¥Starting the Memory Scan function switches OFF the RIT and XIT functions. RIT and XIT are not switched ON again when Memory Scan stops, and the RIT/XIT offset frequency is not cleared.

¥Attempting to use Memory Scan when no data has been programmed in any memory channels, or when all channels are locked out, causes an alarm. Scan will not start.

¥To scan channel 99, cancel Memory Channel Lockout {page 62} for that channel.

Note: Remember to adjust the squelch threshold level {page 19} before using Memory Scan.

BUSY FREQUENCY STOP

The transceiver automatically stops Memory scanning when a signal is detected if Busy Frequency Stop is ON. The transceiver remains on the same channel for either a short time or until the signal drops depending on which Scan Resume method is selected (see below). The squelch must be adjusted to the noise threshold point with no signals present for Busy Frequency Stop to work.

Toggle Busy Frequency Stop OFF or ON via Menu No. 67 (BSY.STOP). The default is ON.

Note: Busy Frequency Stop cannot be used with Program Scan.

■Scan Resume Methods

Scan Resume controls when the transceiver continues Memory scanning after stopping due to a busy channel. Neither of the following two modes function if Menu No. 67 (BSY.STOP) is switched OFF. These modes cannot be used with Program Scan.

Time-operated mode: After stopping, Scan checks the busy channel approximately three seconds later. If the channel is still busy, Scan waits another three seconds then resumes scanning. If the channel is not busy three seconds after stopping, Scan resumes immediately.

Carrier-operated mode: Scan resumes approximately two seconds after the signal drops.

Select your preferred Scan Resume method via Menu No. 68 (CAR.SCAN). The default is Time-operated (OFF).

ALL-CHANNEL SCAN

The All-channel Scan function scans all memory channels containing frequency data.

2Switch OFF Menu No. 66 (GRP.SCAN).

3Adjust the SQL control while no signal is present.

¥The squelch must be closed before scanning starts.

4Press [SCAN] to start scanning.

5To stop scanning, press [SCAN], or [CLR], or [SEND], or Mic [PTT].
