1. Before Installation
  • When selecting mounting location take into consideration: positions of back view mirror, wiper blade paths and defrosting wires (when mounting on rear window). The driver’s view should not be obstructed.
  • Max. allowed curvature of the glass surface on the mounting spot is 2 mm deflection per 100 mm length.
  • Environmental- and car temperature must be above 15˚; C at installation and surfaces to be glued must be dry and clean.
2. Installation

Do not use sealer on rubber gasket or other places.

3. After Installation
  • Allow the silicone gluings to dry off 2 hours at a temperature above 15˚; C. To ensure full strength of the glue, it is recommended to keep the whip off the mount for 24 hours.
4. Tuning Instructions
  • Insert a forward/reflection-type wattmeter between the transmitter and the antenna.
  • Key the transmitter and observe the forward and the reflected power.
  • Adjust the tuning screw on the matching unit until minimum returned power is obtained.

REINSTALLATION KIT

A reinstallation kit including all necessary parts for transfer of the antenna to another vehicle is available under order No. “GF-RK” (130000329).

SAFETY PRECAUTIONS

Antennas mounted on the windscreen may cause relatively high field strengths in the passenger cabin and near the dashboard.

1. To prevent health hazard due to RF radiation, persons must not closer than 30 cm to the antenna whip (transmitter output power to the matching unit: 20 W). (DIN 57 848).

2. The RF signals at the dashboard may cause interference in electronic equipment such as broadcast radio, computer automatics, braking systems, electronic ignition, relays etc. Some cars are more susceptible to disturbances than others. It is the responsibility of the installer to carry out a thorough check of the proper functioning under any conditions of such circuits before finishing installation.

The supplied silicone adhesive contains acetic acid and fungicides. Keep out of reach of children and dispose properly.
