Installing The Antennas; Connection Considerations - Garmin ONDECK GTB 10 Installation Instructions Manual

Installing the Antennas

After mounting the device, you must orient both antennas pointing toward the sky for the best reception.
1 Remove the black, rubber cap from the connector.
2 Loosely attach the antenna to the connector.
3 Orient the antenna toward the sky.
• If you are installing the device on a vertical surface, such as a bulkhead, you must install the antennas
parallel to the black box
• If you are installing the device on a horizontal surface, you must install the antennas perpendicular to the
black box .
NOTE: You must have the antenna oriented properly for the cover to fit.
4 While holding the antenna in the appropriate position, finger tighten the antenna nut.
5 Using the included wrench, rotate the nut another 45 degrees to fully tighten the antenna nut.
The recommended torque applied to the nut is 0.56 N-m (5 lbf-in.), or finger tight plus 45 degrees.
To ensure a water-tight connection, tighten the antenna nut to 0.56 N-m (5 lbf-in.). Over tightening the nut could
cause damage to the device.
6 Place the cover over the connecter.
7 Secure the cover using the small screw and included #0 Phillips screwdriver.
8 Repeat these steps to install the second antenna.

Connection Considerations

When connecting this device to power and to other Garmin devices, you should observe these considerations.
• You must check the power and ground connections to the battery to make sure they are secured and cannot
become loose.
• You must make sure the locking rings are tightened so the power or data connection remains secure.
• Bare wire connections must be water tight if they will be exposed to moisture. You can use heat-shrink type
butt connectors or other water-tight connections.
• To prevent corrosion of the metal contacts, you must cover unused connectors with weather caps.
• For the best connection of the GPS antenna, completely remove the weather cap from the GPS connector.
• If you need to extend the IN/OUT wires, use minimum of 24 AWG (0.08 mm
• You should install a 1 Amp fuse on all relay controls, Boat-in-Use, Bilge 1/2, and Battery 1/2 input wires at the
positive input to the power source.
