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 key had been operated.

Aborting frequency input

If for some reason you do not wish to complete the frequency data input, before

completing the input sequence with .

3-4 Correcting frequency input

Should an error be made while entering frequency data (by pressing the wrong numeric key), it may be

corrected using the ð BACKSPACE facility. This facility enables rapid correction of errors prior to the

completion of entry by the enter key.

Example of frequency data correction while keying 433.250 MHz

(as if you have made a mistake)

ð, the number “7” clears from the LCD

to finalise the correct entry.

3-5 Changing frequency using the ñ and ò keys

The ñ and ò keys provide a convenient method of frequency change.

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

Hz), 1.00 kHz, 2.00 kHz, 5.00 kHz, 6.25 kHz, 8.33 kHz, 9.00 kHz, 10.00 kHz, 12.50 kHz, 20 kHz, 25.00

kHz, 30 kHz, 50 kHz, 100.00 kHz. The tuning step size may also be programmed in multiples of 50

Hz (via the keypad) so that unusual step sizes other than stated are possible.

the ñ key to tune the receiver upward in whichever step size is selected, use the ò to tune the

receiver downward in frequency. You may and hold either key to continuously tune the

receiver in whichever direction is desired, tuning will stop when the key is released.
