AR2700 operating manual

powering up the receiver. Your memory bank and search bank data will
remain intact but any linked banks, frequency pass data etc will be lost.
Method 2 - RESET switch, left side panel
A “soft” microprocessor reset may also be accomplished by momentarily
pressing the reset switch located on the left hand cabinet using a pointed
utensil such as a pin, small screwdriver, sharp pencil etc. It does not matter if
the receiver is switched On or Off at the time.
Your memory bank and search bank data will remain intact but any linked
bank data etc will be lost.
Method 3 - FULL reset [CLR] + [ENT] keys
DO NOT USE THIS KEY SEQUENCE UNLESS ABSOLUTELY NECESSARY.
A FULL MICROPROCESSOR reset is accomplished by holding both the
[CLR] and [ENT] keys while switching On the unit using the [PWR] key.
All memory channels, search banks, pass channels etc will be lost and blank.
As a result the search and scan facilities will not operate until new data has
been entered. Note: It is quite normal for the set to take about 30 seconds
to recover from a FULL reset as all data is being deleted !!! Often there is
no external indication that a reset is in progress so be patient, following a FULL
reset the receiver will power On and the display will show 80 MHz.
16-2 Other possible operational problems
Signals are weak
Check that the attenuator is not switched On (the legend “ATT” is not displayed
on the top line of the LCD).
Ensure the correct receive mode is being used (AM for airband, NFM for point
to point communications - not WFM etc).
Frequency jumps a few kHz
If you have altered the tuning step size for VFO or SEARCH mode, remember
that the receiver frequency must be divisible by the step size. If it is not, the
AR2700 will correct the displayed frequency to the nearest kHz which is
divisible.
Frequencies and memory channels are skipped
Ensure that the frequencies are not in the PASS list and memory channels not
locked out “CH PASS” by reviewing memory contents in memory recall.
