5 MEMORY CHANNELS

General

The IC-R8500 has 1000 regular memory channels, plus 20 programmable scan edge channels and 1 pri- ority channel. 8-digit memory names are programmed into all 1000 channels and 5-digit bank names are programmed into 20 user banks for convenient recall and organisation of frequencies. Moreover, memory channels can store mode information, a tuning step, and ATT (attenuation) information.

NOTE: When memory channels without informa- tion (blank channels) are selected, the frequency is not displayed. Only the memory channel num- ber appears.

The table below gives a general overview of the IC-R8500’s memory channels.

Bank selection

To select regular channel banks:

Push [M-CH• BANK] or [ENT • BANK], one or more times to select the desired channel bank.

The bank indicator shows the selected bank.

Push and hold [BANK] or [BANK] to quickly cycle through the channel banks in the order to , FREE,

AUTO and SKIP.

NOTE: The FREE bank is initially blank and there- fore cannot be selected. In order to select it at least 1 channel must be programmed into the FREE bank. See p. 21.

Convenient: Bank names

The default names of “USR-A” to “USR-T” can be set to your own preference. Refer to p. 20 for program- ming.

To select the programmed scan edge:

Push [PROG] for 1 sec.

PROG and channel number (0P1 to 9P2) appear.
