ignored.  This is useful for tuning through bands with unusual modes and
channel steps.
To reinstate PROGRAM step size, the receive MODE must be returned to
“PROG” using the “MODE SET” input sequence which is accessed by
pressing [2ndF] [3].
6-7  Changing receive mode (PROGRAM)
As mentioned earlier (section 6-6 of this manual), the specification for step and
mode are allocated by departments of  Government following International
discussions.  Like step size, the receive mode...

VHF Civil airband, UHF Military airband and some PMR (Private Mobile Radio)
and utility services.
FM (NFM)
Narrow Band Frequency Modulation - this provides high quality communication
for relatively short distance operation.  NFM is the most common mode used
above 30 MHz with the exception of the airbands.  NFM is widely used on the
VHF bands: VHF Marine band, 2m amateur Band (145MHz), 70cm amateur
band (433 MHz), PMR (Private Mobile Radio) and utilities.
In the absence of a...

legend “ATT” is extinguished when the attenuator is Off.
The selection of attenuator may also be programmed into memory channels
and when defining program search.
 (7)  Memory banks & channels
It is very convenient to store commonly used frequencies into a memory bank
along with mode and attenuator status, this saves having to key the data in
over and over again.  Memory recall is very straight forward and quick when
compared to retyping all data.
Think of memory channels as...

Start by selecting MANUAL mode (the [MANU] key) then key in the frequency
of 88.3 MHz, “mode and step size” are set to the default of PROGRAM.
[MANU] to place the receiver into MANUAL mode
[8] [8] [MHz] [3] [ENT] to select the desired frequency, the
mode and step size will be automatically set by the AR2700
microprocessor.
Press and hold the [ENT] key for more than 1.5 seconds to enter
memory input mode.
The legend “BANK” and “CH” will appear
on the LCD and start to flash to...

If you had previously written memory
data to location “315”, then the
microprocessor will automatically
increment to location “316” or the first
available empty memory channel.  The
microprocessor will always select the
bank number last used unless otherwise
specified.
Should you wish, you may instruct the
microprocessor to “offer” an alternative bank or review the current setting.
While in MANUAL mode use the sequence [2ndF] [SCAN] (the second
function being labelled as BANK....

This is a useful tool for reviewing memory contents and hunting for a specific
channel when you forget where you stored it!  Should you know the number of
the required memory channel, the keypad method of memory recall will be
much faster.
7-4  Transfer of memory channel to VFO
Should you wish to tune away from the memory channel and benefit from not
having to re-enter the frequency, mode, attenuator setting, channel and step,
the data may be quickly transferred from memory to...

“BANK” and “CH” will flash to indicate that memory input is in progress.
Press [0] [0] [0] to select the memory location you wish to over-write
(000), the stored frequency and new frequency data will alternately flash
on the LCD.
Press [ENT] to over-write memory
location “000”.  The data will be
stored and the display will return to
MANUAL mode.
At any time you may abort the memory
input by pressing the [CLR] key, the
display will return to MANUAL mode.

key for more than 1.5 seconds and at the same time holding the [7] key.
Release both keys and the display will remain blank for about 2 or 3 seconds.
The receiver will power up and the selected memory bank data will have been
deleted.   It is also possible to delete ALL programmed data by fully resetting
the microprocessor, this will delete all memory, search, pass data etc.
A FULL MICROPROCESSOR reset is accomplished by holding both the
[CLR] and [ENT] keys while switching On...

For example, to set the frequency 145.500 MHz as the priority channel:
First ensure that the receiver is in manual
mode by checking that the legend
“MANUAL” is displayed on the LCD or by
pressing [MANU].
Enter the required frequency [1] [4] [5]
[MHz] [5] [ENT].
Transfer the displayed data to the priority
channel using the key sequence [2ndF]
[PRIO].

(9)  SCAN - scanning memory channels & banks
The AR2700 has a SCAN mode whereby the contents stored in the MEMORY
CHANNELS ARE AUTOMATICALLY RECALLED AND MONITORED very
quickly for activity - scanned.
* It is important that you do not confuse SCAN and SEARCH modes. *SEARCH mode (covered later in this manual) automatically TUNES THE
RECEIVER THROUGH ALL FREQUENCIES between two specified frequency
limits looking for active frequencies.
