BASIC OPERATION

■ Ship speed indication

When the ship speed data with NMEA 0183 format is
applied, the radar can display the ship speed. Knots
(KT) or kilometers/hour (KM/h) are automatically se-
lected in the normal screen (p. 4) by selecting nautical
miles (NM) or kilometers (KM) respectively. 

q Push [MENU]/[

] several times to call up the

FUNCTION menu.

w Push [Ú] until the “DIST UNIT” section becomes

highlighted. 

e Push [Ω ≈] to turn the ship speed indication to NM

or KM. 

r Push [MENU]/[

] several times to exit the menu

display or push [Ú] once to proceed to the position
display setting.

■ Position indication 

When latitude/longitude data with NMEA 0183 format
is applied, the radar can display the latitude and longi-
tude of your ship’s or cursor position in the bottom of
the display. (To display the CURSOR position, bearing
data is necessary.) (p. 39)

q Push [MENU]/[

] several times to call up the

FUNCTION menu.

w Push [Ú] until “POSN DISP” section becomes high-

lighted. 

e Push [Ω ≈] to select the ship position or cursor po-

sition.

r Push [MENU] several times to exit the menu.

■ Waypoint indication

When waypoint data received from navigation equip-
ment with NMEA 0183 format is applied, the radar can
display the waypoint. To display the waypoint marker,
bearing data is necessary. (p. 39)

q Push [MENU]/[

] several times to call up the

FUNCTION menu.

w Push [Ú] until the “WPT” section becomes high-

lighted.

e Push [Ω ≈] to turn the waypoint indication ON or

OFF.

r Push [MENU]/[

] several times to exit the menu

display.

■ Long pulse function 

To magnify the blips for easier viewing of small targets,
the long pulse and echo stretch (p. 11) functions are
available. When the long pulse is used in the 

3

⁄

4

to 

2 NM range, this function magnifies target echoes to
the backward direction of the target. 

• Pulse selection
q Push [MENU]/[

] several times to call up the

VIDEO menu. (p. 6)

w Push [Ú] until the “PULSE” section becomes high-

lighted. 

e Push [≈] to select the long pulse.
r Long Pulse indication “

” appears in the upper left

of the screen.

t Push [MENU]/[

] several times to exit the menu.

■ Bearing setting

The radar bearing interface accepts NMEA, N+1 or
AUX data format and the bearing can use a magnetic
or true north type. When a true north type bearing is
used, the variation from magnetic north, etc., can be
adjusted on 0.1˚ steps. 

D Setting the bearing type
q Push [MENU]/[

] several times to call up the

FUNCTION menu.

w Push [Ú] until the “BRG” section becomes high-

lighted.

e Push [Ω ≈] to select magnetic or true north type. 

• All displayed bearing readouts show the selected bear-

ing type. 

D Setting the magnetic variation
q Push [MENU]/[

] several times to call up the INT.

SETTING menu.

w Push [Ú] until the “MAG VAR” sections becomes

highlighted.

e Push [Ω ≈] to select an AUTO* or MANUAL varia-

tion. 

r When a MANUAL variation is selected, push [Ú],

then push [Ω ≈] to set the bearing variation. 

t Push [MENU]/[

] to exit the menu display or

push [Ú] once to proceed to the bearing input set-
ting.

*NOTE: NMEA data is required for auto variation. NEVER

select “AUTO” variation without NMEA data, incorrect varia-
tion data may entered.

NOTE: Turn SP (Short Pulse) this function during
normal operation. This function reduces the target
distance resolution. (p. 23)
