Mounting the Receiver
Please read through these instructions thoroughly before
attempting installation. Make sure you completely understand
these instructions before you begin. When in doubt, seek
professional assistance.
The receiver may be mounted at a remote location,
under the dash or behind a panel. However, you may
wish to mount the receiver at a location that allows easy
viewing of the LED status light for immediate indication
of receiver status.
The following items are required to complete the
installation of your GBR 21:
• Antenna mount (standard 1-inch, 14 threads per
inch)
• Hardware (to secure the GBR 21)
• On/off switch (to control power to the GBR 21)
It is recommended that the system be temporarily
hooked up with the wiring and unit placement
approximating the desired final installation. Then check
operation with potential local interfering equipment
turned on and off. For example, other electronic
equipment, fan motors, engine ignition, alternators or
generators can be sources of interference.
