When auto-mode is in operation, receive mode and tuning step size are automatically

selected for you by the AR-ONE microprocessor.

To activate auto-mode or reconfirm its selection while in VFO mode,

Push and hold the MODE key for more than 2 seconds.

The AUT icon appears on the top right portion of the LCD.

Note: Auto-mode is cancelled as soon as the receive mode, tuning step or other related

data

is changed. Remember that auto-STEP and auto-MODE are linked, reselect AUTO-MODE

if either have been adjusted and you require the auto bandplan selection.

2-5-2 Receive mode selection

Any receive mode may be selected at any frequency within the receiver's frequency

coverage. To access the receive mode menu, push MODE, the following modes are

available: AUTO, WFM, NFM, USB, LSB, CW.

Use the main tuning dial or arrow key to

make selection. To accept the selection, push the ENT key.

The specification for channel occupancy, step (separation) and mode are decided by and

allocated by departments of Governments following international discussions.

Not surprisingly the allocation of frequency bands are not the same all over the world and

channel separation (step) varies from band to band. As an example, the channel separation

(step) for the MW (medium wave) band in the U.S.A. is 10 KHz while in Europe and Japan

they are 9 KHz.
