PUSH this key to place the AR8600 into 2VFO mode where you may receive spot frequencies and
‘generally monitor activity’.  The LCD displays two lines of frequency readout, the upper (larger) being
the current receive frequency.  The LCD legend “2VFO” confirms selection with each VFO being
identified as “V-A” and “V-B”.
   again to toggle between VFO-A “V-A” and VFO-B “V-B”.
  to initiate VFO search between the two displayed frequency limits set by VFO-A and
VFO-B, the legend “V-SR” confirms selection...

    toggles the priority facility on/off (assuming that one has already
been assigned using the priority menu).  The LCD legend “PRI” confirms when priority has been
selected.
    to access the priority menu where the data from a memory
channel may be assigned for priority use.  The interval sampling time may also be specified.

1-5-3  Important controls
The bottom row of seven keys are fundamental in the operation of the AR8600.  The  SCAN, SEARCH
and VFO functions are actioned via this set of keys along with the FUNC and CLEAR operations.
FUNCTION KEY 
The function (shift) key (located on the left hand side) is used to select the second function of keypad
facilities.
  to toggle the function status on/off.  A solid reverse legend LCD “FUNC” indicates
when function shift is in operation.  The function status is terminated...

ARROW KEYS
The arrow keys 
ïðñò are laid out as a group of four keys (up, down, left and right).
This format is particularly convenient being placed directly above the main dial.
ð
The right arrow key is used as a backspace when entering frequency via the keypad.
Also selects bank in memory read mode, moves the cursor position (especially during
text input), tunes the receiver and changes values in menus.

on a regular basis, if you are not going to use the AR8600 with the BP8600 for extended periods
(several months), it may be worth considering removing the batteries from the radio (to prevent the cells
deteriorating).  It is most important that they are charged before placing them into storage and reusing
them within at least three months, ideally NiCads should be fully cycled not less than once every month
after they have been placed into use, always charge NiCads before placing them into storage....

1-6-3  Battery considerations
The optional BP8600 battery is not factory charged.  When the BP8600 has been fitted, charge the
battery for 48 hours.  After this time the NiCads should never be left in a flat condition or internal
filaments will form (inside the NiCads) shorting its terminals rendering it useless.  If you are not going
to use the NiCads for a few months, charge them before placing them into storage.  NiCads have a
memory effect, for longevity, once a month flatten them completely then...

1-7  IF output and Spectrum Display Unit (SDU5500)
The rear panel has a 10.7MHz i.f. output designed to drive the SDU5500 optional Spectrum Display Unit.
The AR8600 must be enabled in order to provide the i.f. output, this operation should be carried out in a
workshop.  The WFM circuit of the AR8600 becomes permanently active to achieve a wide bandwidth
(irrespective of receive mode employed), however the usable bandwidth remains smaller than the total
10MHz provided by the SDU5500.  The...

2-1  LCD (Liquid Crystal Display)
All relevant operational information is provided via the central LCD.  To see all the available LCD
legends, and to test the LCD, an LCD test routine has been provided.  
 and hold the 
key then switch the AR8600 on, (then turn the PWR/VOL control clockwise to provide power or if already
