displayed to the right of the kHz position. This is to ensure easy recognition of short wave frequencies
which are often listed as 'kHz' in frequency guides.
If an attempt is made to enter an 'out of range' or invalid frequency (such as 2345 MHz or 0.09 MHz) the
error beep will sound (if beep is enabled) and the LCD returns to the previous frequency prior to
frequency input. Acceptable input range is 0.1 MHz to 2040 MHz.
Note: If you pause during frequency input for more than 90 seconds, the menu will time out
and the AR8200 will return to its previous task just as if the

The speed at which the receiver steps up or down depends upon the STEP SIZE which is default to
AUTO. In AUTO the step size, receiver mode etc is taken from the factory pre-programmed band plan
but may be overridden at any time.
Examples of tuning step include: 0.05 kHz (50 Hz), 0.1 kHz (100 Hz), 0.2 kHz (200 Hz), 0.5 kHz (500
