@1MEMORY SET SWITCH [M-SET] (p. 19)

Used to ‘copy and paste’ the displayed frequency into another memory channel.

•The first push is used to copy ( M appears), and the sec- ond push is used to paste ( M disappears).

•Frequency, mode, tuning step, memory name, etc. can be programmed into a temporary memory.

@2MEMORY CLEAR SWITCH [M-CL] (p. 19)

Push and hold to clear the contents of the displayed memory.

• Bank names cannot be cleared.

@3MEMORY WRITE SWITCH [MW] (p. 19)

Push and hold to store the displayed frequency, mode, tuning step, etc. into the selected memory channel.

@4BANK SWITCH [BANK] (p.17)

➥Push momentarily to toggle the bank limit func- tion ON and OFF (p 18).

•While “BANK” appears, only memory channels within the selected bank can be selected via the [M-CH] se- lector.

➥Push for 1 sec. to increase/decrease the number of memory channels in the selected bank (p. 21).

@5MEMORY CHANNEL SELECTOR [M-CH] (p.18)

➥Selects a memory channel in normal use.

•Clockwise rotation selects higher memory channel numbers; counterclockwise rotation selects lower memory channel numbers.

➥Selects a set mode item when quick set mode or initial set mode is selected (p. 30).

@6DELAY/SPEED CONTROL [DELAY/SPEED] (p.28)

Adjusts the scan delay time or scan speed depend-

•When scan delay time is assigned, this control adjusts the scan delay time (scan pausing interval) during signal

reception. This setting is effective when “ ” is selected for the scan resume condition.

•When scan speed is assigned, this control adjusts the scan speed. In this case, scan delay time is determined while setting.

@7SCAN SWITCHES [SCAN SCAN SET ]

All of these switches are related to the scan function in some way as follows:

[MEMO] (p. 23)

➥Push momentarily to start/stop memory scan.

➥Push numeral keys, then this key to start memo- ry scan in the specified bank.

➥Push this key, then a mode switch to activate mode select scan function.

➥Push for 1 sec. to set automatic bank and skip functions.

•The bank limit function and/or memory skip functions are activated automatically when “AUTO” is selected and scan is started.

[SEL] (p. 23)

➥Push momentarily to start/stop memory select scan.

➥Push for 1 sec. to set the memory channel as a select channel.

[PROG] (p. 24)

➥Push momentarily to start/stop programmed scan.

➥Push numeral keys, before or after pushing this key to start programmed scan using the specified scan edge group.

• 10 scan edge groups are available.

➥Push for 1 sec. to program scan edges for pro-
