menu. the key to toggle the tone eliminator on
and off (default off). Use the main dial to make selection of tone
in 256 steps from 0 to 255, the   keys are used to increment
selection of tone in increments of 10.
When selecting the value, the legend “” will be displayed to the
left of the numeric value to indicate that the displayed tone value
is contained in the current receive frequency, this greatly eases
location of the offending tone frequency to allow scan and search
to continue.
To accept the data input , alternatively to abort entry . When
active, the LCD legend “T.EL” will be displayed in the bottom left corner of the LCD.
Refer to the table to reconcile value with frequency:
Frequency (kHz) 0.4 0.6 1.0 1.4 1.8 2.2 2.6 3.0 3.4 3.8 4.2
Tone value 0 70 160 190 210 220 230 237 240 245 248

Tone eliminator setting and value may be held separately in each VFO, search bank and memory
channel.
The squelch should be set to threshold in the usual manner. Operation continues as normal with the
tone eliminator active, however if a transmission is encountered which contains a ‘pilot tone’ which
matches the current setting of the tone eliminator, the squelch will close allowing the scan and search
processes to continue… i.e. the AR8600 will NOT think that it has found an active receive frequency or
blank carrier.
Note: The tone eliminator does not remove whistles from the loudspeaker, it purely allows
scan & squelch to continue unhindered.
18-4 CT8200 optional CTCSS slot card
The CT8200 enables the AR8600 to search for 50 CTCSS tones which may be in
use on the current receive frequency and to save a specific CTCSS tone (from
the 50 tones available) into each VFO, each search bank and every memory
channel individually. CTCSS is used by many amateur band repeaters, public
utilities and private mobile radio services where shared resources are used,
CTCSS ensures that operators only hear traffic intended for them.
Register the CT8200 slot card
Insert the CT8200 slot card and switch the AR8600 on and REGISTER the
