1.6 Tuning the Receiver

The radar is set for automatic tuning at the
factory.
Automatic tuning
The radar receiver is tuned automatically
each time the transmitter is turned on. The
tuning indicator and the label AUTO at the
top right corner of the display unit shows the
tuning circuit is working. The receiver may
become detuned, in automatic tuning, if own
ship's radar receives the radar signal of an-
other shipborne radar. To retune, press the
[STBY/TX] key twice.
Manual tuning
1. Set up for manual tuning following the
procedure shown below.

tary control to find the best tuning point.

tor lights to about 80% of its total length.
Note that the tuning indication will never
