SeekTech ST-510 Line Transmitter
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,
precautions to carefully
transmitter from the high voltage source.
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.
Wear appropriate heavy soled footwear as you
would when working with any high-voltage
equipment.
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.

European Frequency Set
The Seektech ST-510 as delivered in Europe is
slightly different than the ST-510 delivered in U.S.
Markets.
European frequencies are limited to 95 KHz. The
version of the ST-510 for European markets has a
line
top frequency of 93 KHz. The U.S. version has a 262
kHz frequency capability.
93 Kilohertz Frequency Use
The default 93 kHz frequency has an actual cycle
count of 93,696 cycles per second.
Some older transmitters use a different value for the
nominal 93 kHz frequency, 93,622.9 cycles per
second.
If you find that your transmitter signal at 93 kHz
cannot be detected by your receiver, set the
transmitter's frequency to 93-B kHz, which is set to
the older value. Both 93 and 93-B frequencies can be
found under the Manufacturer's Menu. (See page
20.)
ALWAYS HOOK UP LEADS FIRST BEFORE
POWERING THE UNIT ON TO AVOID SHOCK.
ALWAYS
DISCONNECTING LEADS.
ELECTRIC SHOCK MAY RESULT FROM
FAILURE TO CONNECT LEADS BEFORE
POWERING THE UNIT ON.
Do not handle the transmitter while you are
connected directly to ground yourself.
