The key also allows selection On/Off of certain
options while in menus (such as step-adjust) and selects
defaults in other menus.
- [MHz] [ENT] - TXT ( Cyber Scan )
This key has three main applications:
MHz - the key is used to enter frequencies as MHz while
in VFO mode. For example to enter a frequency of 88.300
MHz follow the key sequence
There is no need to add the trailing zeros to the right,
once the key has been used, the AR5000
microprocessor will automatically add the additional trailing
digits. The display will read "
Note: Frequencies below 3.0 MHz (3000 kHz) will be
displayed as kHz regardless of the entry format. It is
usually more convenient to enter medium wave / long wave
frequencies using the kHz format.
ENT - the key is used as ENTER in many operations and
to complete sequences in most menus.
If the key is held for more than one second while
in VFO mode, the receiver enters memory write mode.
Use the to select channel number to be
overwritten, the
number or key in the three digit memory location using
the numeric keypad. Pressing the
key will enable text comments of up to eight
characters to be added to each memory channel.
The key sequence

where scan and search speeds are approximately doubled
(the frequency display is blanked out during CYBER SCAN
& CYBER SEARCH ).
TEXT - The key sequence
causes the TEXT COMMENTS to be displayed in
memory recall, scan
(in place of the frequency readout).
- ANT
This key activates the RF attenuator menu.
An aerial attenuator system allows selection of AUTO,
0dB, 10dB or 20dB. The attenuator control switches
in / out of circuit the RF preamplifier and attenuator
affecting the sensitivity of the receiver. 20dB may not be
selected above 230 MHz. RF gain is also available in all
modes via a front panel rotary control, this is especially
useful in providing optimum audio quality for SSB
operation.
The selection of attenuator is made using the

The sequence
held for more than one second activates the M.TUNE
AUTO / MANU RF input preselection for frequencies up
to 999.999999 MHz. The default is AUTO where the
microprocessor controls the RF front end preselection.
However if strong adjacent-channel interference is
experienced, the preselection may manually moved
off frequency reducing interference. Under this situation
the on channel sensitivity will generally be reduced to
some degree, for this reason do not manually tune the
preselector too far away from the start point.

- UP
This key has three functions:
UP - if quickly pressed causes the displayed frequency in
VFO mode to be incremented in an upward direction by
one step. The key may be pressed to force the scan and
search onward past a busy frequency or channel, it may
also be used to reverse the direction of scan and search.
If held for more than one second while in VFO mode,
frequency search is initiated. If held for more than one
second while in memory recall mode, the scan process
will start.
INCREMENT - the key will often increment menu options
such as DTMF to T.ELMT etc. While in TEXT write mode,
the key will move the cursor one space to the right.
BACK SPACE - if an error is made while keying in
frequencies in VFO mode, the

all digits are deleted, the display will return to the previous
frequency.
