2. RADAR, CHART RADAR
OPERATION
2.1 How to Transmit
After the power is turned on and the magnetron has warmed,
"ST-BY" appears at the screen center, meaning the radar is
ready to transmit radar pulses. You can transmit by pushing
the STBY/TX key on the Control Unit, or clicking the [STBY
TX] button on the Status bar.
The radar is initially set to previously used range and pulse length. Other settings such
as brilliance levels, VRMs, EBLs and menu option selections are also set to previous
settings.
The STBY/TX key (or [STBY TX] button) toggles the radar between STBY and
TRANSMIT state. The antenna is stopped in stand-by and rotates in transmit. Set the
radar in standby when its use is not required, to conserve the life of the magnetron.
2.2 How to Tune the Radar Receiver
After the radar is transmitting, adjust the receiver to the exact frequency of the trans-
mitter, automatically or manually. The current tuning method and tuning status is
shown at the top-left position.
2.2.1 How to initialize tuning
Automatic tuning is initialized during the installation. However, if you feel that automat-
ic tuning is not working properly try re-initializing the tuning. Right-click the [TUNE] but-
ton then select [Tune initialize] to start the initialization.
2.2.2 Automatic tuning
Click the [TUNE] button on the InstantAccess bar to display [TUNE AUTO].
2.2.3 Manual tuning
To tune the radar, start by setting the brilliance to a comfortable level, adjusting the
gain until the background speckle just disappears, and selecting the 48-mile range.
Then, do the following:
[STBY TX] button
[TUNE] button
