Fine Tuning of Received Frequency (RIT)
Some�mes a sta�on will come back off-frequency. Rather than tuning your
frequency to the other sta�on’s it’s be�er to add some “
R
eceiver
I
ncremental
T
uning” to correct the other sta�on’s frequency.
Line Input and Output
The G90/S has an external line input interface. When the G90/S is used for
data communica�on in conjunc�on with a computer or an external modem,
the correct signal input op�ons need to be selected.
Opera�on of Line Output
In the system menu, select: AUX OUT VOLUM and set it to the appropriate
output level. Your computer so�ware package will have a meter showing best
input levels.
Opera�on method:
1. A long press of the main tuning knob enters the RIT adjustment interface.
2.
Rotate the main knob le� or right to adjust the RIT value. The adjustment
range is ±500Hz.
When RIT is no longer required, reset the RIT value to 0.
When using digital communica�ons via the ACC port, the TX audio drive
level should be capable of 200mv.
Feed the external audio signal into the corresponding pin of the ACC port
(see the interface descrip�on on page 10).
Select the LINE input op�on under the INPUT se�ng reached by pressing
the [FUNC] once and [POW] bu�on twice.
In the system menu, select: AUX IN VOLUM to set the appropriate input
