How to Set Up the Fish Finder

To set up the fish finder, follow the procedures in this section.
3.4.1 Fish finder initial settings
1. Tap the [Home] icon to show the [Home] screen, then tap [Settings] => [Fish Find-
er] => [Initial Setup], to show the fish finder settings.
2. Referring to the table below, set up the fish finder menu.
Menu item
[Transmission Power] Select [High] or [Low] as required.
[Transducer] Select the transducer which is connected to your GP-1x71F.
Drag the menu to show transducer types which are not displayed on the
screen.
Note 1: Select the correct transducer. Incorrect selection may cause er-
rors or malfunctions.
Note 2: For transducers with a TDID, this setting is not required, as the
system automatically detects the transducer.
[Transmit Rate] Select [Auto] or [Manual] transmission rate as required.
For [Manual], select the transmission rate with the slider bar, or enter a
value between [0] and [20] with the software keyboard.
[LF Echo Offset], Apply offsets to the gain for Low/High Frequency.
At factory default ([0]), the strongest consecutively detected echo is rec-

[HF Echo Offset]*
ognized as the seabed. If the seabed is not shown on the display, lower
the setting. If the fish finder shows the seabed at a shallower location
than the actual seabed, increase the setting.
Note that too low a setting may mistake fish for the seabed. Conversely
an extremely high setting may not correctly detect the seabed.
[LF Bottom Level], Apply offsets to the seabed level for Low/High Frequency.
Only adjust this setting if the gain is not automatically adjusted correctly.
2
[HF Bottom Level]*
[Smoothing] Select whether or not to smooth the displayed echoes.
[Depth Indication] Select whether or not show the depth indication. Select [Small] or
[Large] to show the appropriately size indication, or [Off] to hide the in-
dication.

* : For CHIRP transducers, this menu appears as [Gain].
2
* : For CHIRP transducers, this menu appears as [Bottom Level].
3. At the left-side of the screen, in the top layer of the menu, tap [Sensor Setup].
4. At [Draft], tap the keyboard icon to show the numerical keyboard.
5. Enter the draft value, then tap the [OK] button at the bottom-right of the keyboard.
6. At [Calibration], select the item you want to offset (calibrate), as required.
• [Speed]: Offsets the sensor-detected speed.
• [Temp °F]/[Temp °C]: Offsets the sensor-detected water temperature.
• [Acoustic Speed m/s]: Offsets the speed for each sonic pulse emitted by your
transducer.
7. Tap the [ ] at the top-right of the screen to close the menu.

How to Set Up the Radar

3.5.1 How to connect to the DRS4W Radar Sensor
If you have a DRS4W radar antenna, you can connect to the antenna via wireless
LAN. Before adjusting settings for the radar, make sure the antenna is turned on.
Note: For how to turn the DRS4W on/off, see the DRS4W Operator's Manual OME-
36360-xx ("xx" indicates version number).
When connecting to the DRS4W, the following information is required.
• DRS4W SSID, supplied with the DRS4W when installed.
• DRS4W password, supplied with the DRS4W when installed.
On the GP-1x71F, do the following procedure.
1. Tap the [Home] icon to show the [Home] screen, then tap [Settings] => [General]
=> [Wireless LAN].
2. Tap the toggle box inside the [Wireless LAN Antenna] section to show [ON]. The
system checks for available wireless connections and shows the available SSIDs
in the [Networks] list.
3. Tap the SSID of your DRS4W. The password input screen appears.
4. Input the password, then tap [OK]. If the password is correct, the system connects
to the DRS4W and the SSID appears in the [Active Networks] section.
5. Tap the [ ] icon at the top-right corner of the menu to close the menu.
6. Tap the [Home] icon to show the [Home] screen, then tap [Settings] => [Radar] =>
[Initial Setup], to show the radar settings.
7. Referring to the following table, set up the radar.
Menu item
[Tune Initialize] Settings: [ON] (default), [OFF].
Enable/disable auto tuning for the radar.
[Random Pulse] Settings: [ON] (default), [OFF].
Enable/disable random changes in pulse transmission rate, to reduce
interference from other radars.
[On Time] Display only.
Shows total time the radar has been turned on.
[Tx Time] Display only.
Shows the total transmission time for the radar.
[Sector Suppression] Settings: [ON] (default), [OFF].
Enable/disable sector suppression to stop transmission in a defined
sector.
[Sector Start Angle] Setting range: 0.0° (default) to 359.9°.
Sets the start angle for sector suppression. This setting is only applied
when [Sector Suppression] is set to [ON].
[Sector Width] Setting range: 0.0° (default) to 135.0°.
Sets the sector width for sector suppression. This setting is only applied
when [Sector Suppression] is set to [ON].
[Video Contrast] Settings: [0] (default), [1], [2], [3]
Sets the contrast level for the radar display.
[Antenna Heading Align] Aligns the antenna heading. Use this menu item only when the antenna
is not facing directly towards the bow at installation. See section 3.5.2
for details on how to use this menu.
8. Tap the [ ] icon at the top-right corner of the menu to close the menu.
