How to align the antenna heading
You have mounted the antenna unit facing straight ahead in the direction of the bow.
Therefore, a small but conspicuous target dead ahead visually should appear on the
heading line (zero degrees).
In practice, you will probably observe some small bearing error on the display because
of the difficulty in achieving accurate initial positioning of the antenna unit. The follow-
ing adjustment will compensate for the error.
1. Turn the boat towards a target. The target should be oriented directly forward of
the bow.
2. Tap the [Home] icon to show the [Home] screen, then tap [Settings] => [Radar] =>
[Initial Setup], to show the radar settings.
3. Scroll to the bottom of the menu, then tap [Antenna Heading Align]. The system
switches to the Radar page.
The data box at the bottom-right of the radar page shows indications for "EBL",
"VRM" and "Heading". The radar page also show a [Cancel] button and a [Save]
button at the top of the page.
4. Use the range slider to adjust the heading. Tap the plus/minus, or drag the slider
until the target selected at step 1 is displayed at the top-center of the screen.
Confirm that the "Heading" indication at the bottom-right of the screen shows the
correct offset value.
5. Tap [Save] to save the settings and return to the standard radar page.

INPUT/OUTPUT DATA
The GP-1x71F can connect to temperature sensors, speed sensors and other
NMEA0183 or NMEA2000 compatible sensors. To connect and communicate with
most sensors, sensor settings in the [Interface] menu must be completed.
4.1
How to access the [Interface] menu
The [Interface] menu contains menus for NMEA0183 and NMEA2000 devices. To ac-
cess the Interface menu, follow the procedure below.
1. Tap the [Home] button at the top-left of the screen to show the [Home] page.
2. Tap [Settings] => [Interface]. The [Interface] menu appears.
For the sake of brevity, above two steps are written as "Open the Interface menu" in
the following sections.
4.2
How to set up the NMEA0183 port
1. Open the [Interface] menu.
2. Tap [NMEA0183 Setup]. The [NMEA0183 Setup] menu appears.
3. Tap [Baud rate], then select the baud rate for your NMEA0183 sensors.
4. Tap the [<] at the top-left of the [Baudrate] options to go back to the [NMEA0183
Setup] menu.
5. Tap [Format], then select the NMEA0183 format for your NMEA0183 sensors.
6. Tap the [<] at the top-left of the [Format] options to go back to the [NMEA0183 Set-
up] menu.
7. Tap the [
u
] at the top-right of the screen to close the menu.
4.3
How to select a data source
1. Open the [Interface] menu.
2. Tap [Select Input Device].
3. At the left side of the [Select Input Device] menu, tap the data whose sensor you
want to set up. The [Input Device] list appears to the right of the screen.
4. Select the input device (data source).
•
[Internal GPS]
: Uses the internal GPS beacon to calculate/display data.
•
[Internal FF]
: Uses the internal Fish Finder to calculate/display data.
•
[NMEA0183]
: Uses the connected NMEA0183 sensor to calculate/display data.
•
[NMEA2000 Auto]
: Automatically selects a NMEA2000 device (connected to
the same network) to calculate/display data. If communication with the connect-
ed device is lost or interrupted, the next available NMEA2000 device for that
data type is selected.
