(7) SCAN - scanning memory channels & banks
The AR8200 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.

7-1 SCAN - outline introduction

During SCAN, the AR8200 automatically recalls each memory channel which contains data in numeric
order and monitors it looking for activity. When an 'active' memory channel is located (when a signal is
found and the squelch is open) the AR8200 will temporarily stop scanning.
At default when shipped from the factory, the AR8200 will remain on the active memory channel until
the received signal disappears and the squelch closes. The CPU will then wait a further 2 seconds in
case a reply is audible (such as aircraft and air traffic communications) and will then resume scanning
the memory channels again.
If the keys are pushed or the main dial rotated (while scanning or when stopped on an active
channel), the receiver resumes scanning in the direction of the arrow key or rotation. This is particularly
useful for taking a second look a channels which have just been scanned.
Additional facilities available in SCAN
Memory banks may be "LINKED" and "UNLINKED" to effectively make larger or smaller groups of
memories which may be scanned together.
"PASS" may be used whereby memory channels can be skipped when not required (such as when
permanently busy), they may be easily reinstated at a later time.
"AUTO STORE" reserves memory bank "J" so that active frequencies found while conducting a
SEARCH may be automatically written to memory. This is a useful tool for compiling an activity list of
rarely used frequencies especially when unattended. Refer to section 8-7-5 of this manual for further
information relating to auto store.
It is possible to alter the sequence of scanning events using the SCAN ENVIRONMENT menu. There
are several scanning parameters which may be changed to suit your preferences and requirements
DELAY, LEVEL, VOICE, FREE & MODE, it is possible to mix combinations of all parameters.

7-2 SCAN considerations

It is presumed that you have already stored your favourite and commonly used frequencies into the
memory banks (as per section 5-2 of this manual).
A total of 1,000 memory channels are provided which are divided into 20 banks, each (at default) having
50 channels. The memory banks are identified by letters A, B, C, D, E, F, G, H, I, J (upper case letters)
and a, b, c, d, e, f, g, h, i, j (lower case letters) and numbered from 00 to 49.
