5 MEMORY CHANNELS

Assigning channel numbers

The IC-R8500 has 20 banks in which memory chan- nels can be programmed and arranged. By default, each bank contains 40 memory channels, however, channels can be deleted from or added (inserted) to banks to suit your preferences and operating style.

Deleted channels are stored temporarily in the “FREE” bank.

NOTE: When shipped from the factory or after resetting the receiver’s CPU, the “FREE” bank has no memory channels and cannot be selected.

To rearrange bank channel assignments:

Delete memory channels from banks that have more memory channels than you need.

Deleted channels are assigned to the ‘free’ bank auto- matically.

Add (or insert) memory channels to banks in which you want to add channels.

Channels added to a bank are deleted from the ‘free’ bank.

DDeleting memory channels

Select the bank and memory channel you wish to delete.

Push [BANK] for 1 sec.

One of “INS. 1CH,” “DEL. 1CH,” “ADD.10CH,” or “ADD. 1CH,”appears and flashes.

Push [BANK] momentarily to exit the condition and return to the previous display, if desired.

Rotate [M-CH] until “DEL. 1CH” appears in the display.

Push [BANK] for 1 sec. to delete the selected channel.

The memory channel (but not its contents) is moved to the “FREE” bank.

Memory channels can only be deleted one at a time to prevent accidental deletion of multiple channels; when you want to delete more than one channel from a bank, repeat the above steps as many times as necessary.

NOTE1: Deleted channels are moved to the ‘free’ bank, however, the programmed contents are erased.

NOTE2: The number of banks cannot be decreased. This means that if there is only one channel in a bank, it cannot be moved to the ‘free’ bank.
