Notices

This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to
Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications. Operation of
this equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Changes or modifications to this equipment not expressly approved by NovAtel Inc. could result in violation of
FCC and CE Marking rules and void the user's authority to operate this equipment.

To maintain compliance with the limits of a Class A digital device, you must use properly
shielded interface cables when using the serial ports. Appropriate cables include Belden #9539,
or equivalent, and Belden #8770 cable for input power source (ensuring the shield is connected
to the protection ground).

CAUTION:
Double pole/neutral fusing

CAUTION:
The G-III Reference Receiver must be installed in a Restricted Access Location only.

The G-III Reference Receiver is not user-serviceable. In the event of any failure of the unit, do
NOT remove any cards or covering panels from the unit. Return the unit to the factory for repair.
Lightning Protection Notice
What is the hazard?
A lightning strike into the ground causes an increase in the earth's potential which results in a high voltage
potential between the center conductor and shield of the coax cable. This high voltage develops because the
voltage surge induced onto the center conductor lags in time behind the voltage surge induced onto the shield.
Hazard Impact
A lightning strike causes the ground potential in the area to rise to dangerous levels resulting in harm to
personnel or destruction of electronic equipment in an unprotected environment. It also conducts a portion of
the strike energy down the inner conductor of the coax cable to the connected equipment.

Only qualified personnel, electricians as mandated by the governing body in the country of
installation, may install lightning protection devices.
Actions to Mitigate Lightning Hazards
1. Do not install antennas or antenna coaxial cables outside the building during a lightning storm.
2. It is not possible to avoid over-voltages caused by lightning, but a lightning protection device may be used
to shunt a large portion of the transient energy to the building ground reducing the over-voltage condition
as quickly as possible.
