navigation due to operation of the radar.

All cables of the radar are to be run away from the cables of radio equipment.

(Ex. Radiotelephone. Communications receiver and direction finder. etc)

Especially inter-wiring cables between scanner unit and display unit of the radar

should not run parallel with the cables of radio equipment.

 Wait approximately 10 seconds before turning on the power again.
 A malfunction may occur if the power in the ship is suddenly interrupted during

operation of the radar. In this case, the power should be turned on again.

 Immediately after the radar is installed, if the system is not used for a long time,

or after the magnetron is replaced, warm-up the equipment in the standby mode
for 20 to 30 minutes before setting it to the transmit mode.

 If the warm-up time is short, the magnetron may cause sparks, resulting in an

unstable oscillation.
Start transmission on a short-pulse range and then send long pulses
sequentially. If the transmission is unstable in the meantime, reset the system
to the standby mode immediately and maintain it in the standby mode for 5 to 10
minutes before restarting the operation. Repeat these steps until the operation
is stabilized.

3.3 PREPARATION

Tuning [TUNE]････････････････････････････････････････････

This control is used to tune the receiver.
If the receiver is detuned from the best level, the receiving sensitivity falls, and the targets on a long
range or the small targets on a short range may be overlooked.
In manual tuning, rotate the [TUNE] control clockwise or anticlockwise and adjust so that the target
echoes are the clearest. If no suitable target is present, adjust the control so that the tuning
indicator bar graph at the upper left of the radar display is maximized.
After setting the radar to the TRANSMIT mode, it take about 10 minutes until the oscillation
frequency of the magnetron is stabilized. Therefore, tune the receiver once again after about 10
minutes.
For automatic tuning, set “TUNE” to “ON” in the AUTO Menu. (Refer to page 3-8).

Sensitivity Control [GAIN]･････････････････････････････････

This control is used to control the radar receiving sensitivity.
Clockwise rotation of the [GAIN] control increases receiving sensitivity and extends the radar
observation range. If the sensitivity is too high, the receiver noise will increase to reduce the
contrast of the targets with the background video and make the targets obscure on the display. To
observe densely crowded targets or the targets on a short range, rotate the [GAIN] control
anticlockwise to reduce the sensitivity so that the targets are easy to observe. Be careful not to
overlook small and important targets.

Display Brilliance Control ･････････････････････････････････

This control is used to adjust the brilliance of the entire display.
Clockwise rotation of the [BRILL] control increases the brilliance of the entire display. Adjust the
[BRILL] control to obtain the best-to-see display with optimum brilliance.

 In the AUTO SEA mode, there are cases in which the targets are not displayed

because the sea clutter returns are suppressed in a simple way.
Use the manual [SEA] control during sailing under normal conditions.

 In the AUTO RAIN mode, there are cases in which the targets are not displayed

because the rain/snow clutter returns are suppressed in a simple way.
Use the manual [SEA] control during sailing under normal conditions.

Contrast Control [BRILL VIDEO]･･･････････････････････････

The contrast of the radar video display can be adjusted in four levels. Press the PANEL button on
the screen, then select [BRILL VIDEO]. Each time the brilliance button is clicked, the screen
will switch to VIDEO . The current mode is displayed on the lower right of
the radar screen. (The VIDEO indication will change to the PANEL indicated in several second.)
Adjust the [BRILL VIDEO] switch to obtain the best-to-see video with optimum contrast.

Sea Clutter Suppression [SEA]････････････････････････････

This control is used to reduce the receiving sensitivity on a short range to suppress the sea clutter
returns.
Clockwise rotation of the [SEA] control can suppress sea clutter returns more effectively. Be
careful not to suppress sea clutter excessively. Otherwise, small buoys and boats may disappear
from the radar display.
When setting “SEA” to “SEA AUTO” , sea clutter returns can be suppressed depending on their
intensity levels. This setting is used for the case in which the sea clutter returns are different in
their directions.
Switching between manual and auto is done by clicking the“SEA AUTO” / “SEMI AUTO”button on
the lower left of the screen, or pressing the“SEA”knob.

Note: It is not allowed to use both the AUTO / SEMI AUTO SEA mode and the AUTO

RAIN mode at the same time.

Rain/Snow Clutter Suppression [RAIN]･････････････････････

This control is used to suppress rain or snow clutter returns. Clockwise rotation of the [RAIN]
control makes clearer those targets that may be hidden among rain/snow clutter returns. Be
careful not to overlook small targets in the clutter. This control also has the effect of reducing sea
clutter, so that it is more effective to use this control together with the [SEA] control.
Rotate the control anticlockwise to the maximum in the normal condition.
When setting SEA/RAIN to AUTO RAIN in the AUTO Menu, rain/snow clutter can be suppressed
depending upon the intensity level. When setting SEA/RAIN to MANUAL in the AUTO Menu, the
mode is changed into the MANUAL mode.
Switching between manual and auto is done by clicking the "RAIN AUTO" button on the lower left of
the screen, or pressing the "RAIN" knob.

Note: It is not allowed to use both the AUTO RAIN mode and AUTO SEA mode at the

same time.

Brilliance Control････････････････････････････････････････

Press . Or press the right side of "PANEL" on the screen.

The BRILLIANCE switches [PANEL], [BRILL VIDEO], and [BRILL ARPA] are used to adjust the
brilliance of the panel, video and ARPA markers. Each time a switch is pressed, the brilliance is
increased by one level up to 4 or 5 levels. When the maximum level is reached, the brilliance is
reset to the original panel.

[PANEL] Adjusts the lighting for the characters on the controls and switches on the

operational panel.

When PANEL on the screen is pressed, the adjustment status of "BRILL

VIDEO" and "BRILL ARPA" are changed.

Then, each of the levels can be set if the brilliance level button on the right is

pressed.

[BRILL VIDEO] Adjusts the brilliance of radar display.
[BRILL ARPA] Adjusts the brilliance of ARPA information
