in the U.S.A. is 10 kHz, and is 9 kHz in Europe and Japan.

For above reasons, it is necessary to change the frequency step size according to the local band plan.

The AR5001D has been pre-programmed at the factory with all the band plan data (specific to each market

area) so that the AR5001D will automatically select the appropriate step size and mode for the frequency

chosen. This greatly simplifies operation of the receiver while you are familiarizing yourself with all the

functions.

The pre-programming of step size may be manually overridden so you may choose alternative settings

at will or when band plans are updated.

If you wish to change the default tuning frequency step, press the [STEP] key. The LCD will display the

current frequency step and the blinking “STEP” while waiting for the new parameter. Use the sub dial to

select the desired step.

To accept the displayed tuning step size, press the [MHz] key.

The tuning step size may also be programmed in 1 Hz (via the keypad) so that unusual step sizes other

than those stated are possible. The acceptable step size range is less than 1 MHz in 1 Hz steps.

3-8 IF BANDWIDTH

The IF bandwidth selects how SELECTIVE the receiver will be when monitoring signals off air. However,

it is not simply a case of using the narrowest filter at all times; particular modes require differing amounts
