Setting Scan Speed, Memory Channel Lockout

10SCAN GROUP SCAN

SETTING SCAN SPEED

For the purpose of Group Scan, the 100 Conventional memory channels are divided into 10 groups each containing 10 channels. The channels are grouped as follows:

¥00 ~ 09, 10 ~19, 20 ~ 29, . . . . 90 ~ 99

The transceiver only scans memory channels that belong to the specified group and contain frequency data.

1Recall a Conventional memory channel.

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

3Press Mic [UP] or [DWN] to select any memory channel belonging to the channel group that you want to scan.

¥Select the correct group before starting to scan; you cannot change groups while scanning.

4Adjust the SQL control while no signal is present.

¥The squelch must be closed before scanning starts.

5Press [SCAN] to start scanning.

6To stop scanning, press [SCAN], or [CLR], or [SEND], or Mic [PTT].

MEMORY CHANNEL LOCKOUT

Memory channels that you prefer not to monitor while scanning can be locked out. Lock out any memory channel with the following procedure.

Scan speed can be changed through 9 steps using the RIT/XIT control. A weight value of the form ÒPnÓ appears on the Display during Scan. ÒnÓ is a number from 1 to 9 that acts as a speed reference number. Turning the RIT/XIT control clockwise decreases the scan speed, and counterclockwise increases the speed. The Program Scan and Memory Scan speeds can be independently set as explained below.

The table below shows the time required for one frequency step (Program Scan) or one memory channel step (Memory Scan). For Memory Scan, if Menu No. 67 (BSY.STOP) is ON, the weight value is locked at 1. However, if Menu No. 67 is OFF, the stop time on each channel is as shown below.

Weight Value	Program Scan	Memory Scan1
(Pn)	(sec/ 10 kHz)	(sec/ channel)
n=01	8	0.4

n=02	13	1.8

n=03	21.3	3.2
n=04	34.7	4.6

n=05	56.6	6.0
n=06	92.2	7.5
n=07	150.4	9.0

n=08	245.3	10.5

n=09	400	12.0
