Entering Frequencies (Using The Keypad) - AOR AR2700 Operating Manual

It is best to press the [MANU] key at this
time to place the receiver in a known state
of operation... MANUAL MODE.
Note: If the keypad or [DIAL] is not
operated for approximately 30 seconds
while inputting data through a selection
input option, the operation will time out
and the receiver will return to its previous
task just as if the [CLR] key had been
pressed.
6-3 Entering a frequency through the keypad - VFO (MANUAL) MODE
When the [MANU] key is pressed, the receiver enters manual mode ready for
input of a frequency or other data. The receiver may also be tuned using the
[DIAL] just like a VFO. The term VFO historically means "Variable Frequency
Oscillator" and today refers to a tunable data store which contains frequency,
mode, step and attenuator information.
Press the [MANU] key to first select "MANUAL" - VFO mode (should the
receiver be scanning or searching etc).
Example of frequency entry 145.800 MHz
Press [1] [4] [5] [MHz] [8] [ENT]
There is no need to key in the trailing
zeros to the right of the decimal point as
they are automatically added by the
microprocessor.
If keying in a whole MHz such as 118.000
MHz there is no need to key in either the
decimal point or trailing zeros, they are all
added automatically by the AR2700
microprocessor.
Example of "MHz round number" frequency entry for 118.000 MHz
Press [1] [1] [8] [ENT]
If for some reason you do not wish to complete the frequency data input, press
[CLR] before completing the input
sequence with [ENT].
If an attempt is made to enter an out of
range or invalid frequency (such as 1929
MHz or 0.09 MHz) the set will not receive
and invalid frequencies may appear on the
LCD, you may also see error messages
such as "PLL Err" (PLL error) or similar.
