DO NOT HANDLE THE TRANSMITTER WHILE
YOU ARE CONNECTED DIRECTLY TO
GROUND YOURSELF.
The line transmitter is normally powered by
internal batteries, and is designed to protect the
user from voltages up to 240 VAC that may be
accidentally encountered. Powering the line
transmitter by batteries provides the highest level
of isolation and safety, and is therefore the
recommended power source.
The line transmitter may also be powered by an
optional external power supply. The user must
ensure that the external power source is fully
isolated from ground and from the power mains.
The user is cautioned to use only external power
sources recommended by the manufacturer. If a
line transmitter is powered by an external source
that is not isolated from ground and from the
power mains, the line transmitter is not protected
from connection to live power lines! The line
transmitter may be destroyed and may present a
safety hazard. DO NOT USE NON-ISOLATED
POWER SUPPLIES WITH THE LINE
TRANSMITTER.

BEFORE
If the line transmitter is powered by a vehicle 12
VDC cigarette lighter connection, and the line
transmitter is connected to a power line, the
vehicle is now connected to that power line. The
vehicle is now at a potentially lethal voltage. If
the vehicle is grounded, the line transmitter may
be destroyed.
Note: Connection To Energized Conductors
The line transmitter is designed to withstand up to
240 VAC 50/60 Hz excitation between the two
leads. The user is cautioned not to deliberately
connect to live power lines. The protection is not
intended to be used continuously. If the transmitter
indicates the presence of high voltage, use high
voltage precautions to carefully disconnect the line
transmitter from the high voltage source.
European Frequency Set
The NaviTrack 10-watt transmitter as delivered in
Europe is slightly different than the version delivered
in U.S. Markets.
European frequencies are limited to 95 KHz. The
version of the NaviTrack transmitter for European
markets has a top frequency of 93 KHz. The U.S.
version has a 262kHz frequency capability. See
instructions on page 9 concerning the use of these
frequencies.
