channels

Memory mode is used for operation of memory channels
which have programmed frequencies. PreSet channels are
used for most-often used frequencies for quick recall.

*Appears only when PreSet channels/TV channels are

programmed via the optional CS-R20.

†

Available for the USA version only.

Push

[MR S.MW]

to select the memory mode, PreSet, TV

or Weather channel in sequence.

Rotate
