2.3 Automatic Distortion
Compensation
Magnetic field distortion can be automatically
corrected as follows:
Note: This function is only effective after cor-
recting for magnetic field distortion (refer to
page 5).
1. Press the [AUTO] key more than two sec-
onds to light the AUTO LED.
AUTO
TRUE CALIB STATUS
:On
:Off
:State depends on settings
Figure 20
2. To cancel automatic compensation, press the
[AUTO] key more than two second to turn
off the AUTO LED.
Note 1: Turn off this function when your boat
is near a steel ship or iron bridge, since they
affect sensor performance.
Note 2: Correct distortion whenever you feel
error is excessive.
2.4 Selecting Output Data
Format
The PG-1000 can output heading true or mag-
netic. The default setting is magnetic heading
in AD-10 format.
CAUTION
CAUTION
Turn off the autopilot before selecting
output data format.
The autopilot may turn the rudder suddenly.
1. Connect Furuno GPS Navigator to PG-
1000.
RMC or VTG data is required which
contains GPS position in RMC, SOG
(speed over ground) and COG (course
over ground) in VTG.
2. Set up magnetic variation (manual or auto-
matic) at the GPS navigator.
3. Press the [TRUE] key more than two sec-
onds.
The TRUE LED blinks. It lights when
receiving data from the navaid.
AUTO TRUE

When receiving magnetic
variation data from the navaid.

Note: If the TRUE LED dose not light within
90 seconds after pressing the [TRUE] key,
check that the GPS navigator is connected and
properly working.
4. To return to magnetic heading output, press
the [TRUE] key more than two seconds to
turn off the TRUE LED.
Note 1: If the PG-1000 stops receiving mag-
netic variation data while outputting true head-
ing, the TRUE LED stops lighting and blinks.
The last used variation data is used.
Note 2: Magnetic variation cannot be corrected
manually at the PG-1000. Therefore, if you
desire true heading output but do not have a
navigation aid, you may enter appropriate
variation as shown in 1.6 Heading Alignment
on page 6.
Note 3: HDM and HCC sentence are magnetic
heading output sentences. HDG sentence must
be changed to true heading at the equipment
connected, by using the magnetic heading and
magnetic variation data in the sentence.
