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 automatically in the normal course

of entry.

to initiate double-shift which is used in certain menus as a short-cut. The reverse

“FUNC” legend flashes when double-shift is engaged.

Note: When the “FUNC” legend is displayed in VFO mode, the tuning speed will be

increased to assist rapid frequency change using the arrow keys and main dial.

The KEY LOCK is intentionally small to reduce the chances of accidental operation. Key

lock is useful when you do not wish an important frequency to be lost or the AR8600 to be

incorrectly set to a different frequency. The key lock status is not deactivated by switch

off / on, the and keys are not affected by key lock.

to toggle the key lock on /off, an LCD key symbol “ ” indicates status.

The MONITOR key is used to force the squelch open so that you may manually intervene to ensure that

no weak signals are missed. and hold the key to defeat the squelch control (saves

turning the squelch control fully anti-clockwise then back to threshold position).

When the “DUP” legend is displayed during frequency offset or VFO SCAN (DUPLEX) operation, the

key forces the AR8600 to switch to the alternative frequency.

In SCOPE mode, the key enables the reception of the marker frequency.

MAIN DIAL

This large rotary control is intended to be rotated using your fingers and thumb or by

placing your thumb on the edge and rotating using a circular movement. Primarily this is

the tuning control, clockwise rotation tunes the AR8600 upward in frequency and anti-

clockwise rotation tunes downward in frequency using the selected tuning step size.

When the “FUNC” legend is displayed, the tuning speed will be increased. The main dial

is also used to move between menus and manipulate input through menus (generally

mimicking the arrow keys).
