Sources of electrical interference
High power signals from a nearby radio or radar transmitter can overwhelm the receiver circuits. This does
not harm the instrument, but can prevent the electronic receiver from working properly.
Avoid placing the receiver or antenna at least 400 meters from the following sources of electricity and / or
magnetic noise:
●
Powerful Radar
●
Gasoline engines (spark plugs)
●
TVs and computer monitors
●
GNSS antennas.
●
Alternators and generators
●
Electric motors
●
Equipment with DC-AC converters
●
Fluorescent lights
●
Switching power supplies
Low-power transmitters such as cell phones and two-way radios normally do not interfere with the operation
of the receiver.
It is recommended that you use an uninterruptible power supply (UPS) to power the receiver. A UPS protects
equipment from surges and spikes, and keeps the receiver operating during power outages of short duration.
