ntended Use
The CARLOC eries receivers are designed to locate buried pipes and cables. Over 70 frequencies
and four modes of operation are available to suit your specific locating needs.
The 5W and 12W transmitters place signals on target cables to be detected by CARLOC eries
receivers. These units can be configured to send over 70 frequencies as well as custom frequencies.
The transmitters place a signal on the cable through either direct connection, induction clamping, or
broadcast modes.
The fault probe accessory is designed to locate fault signals generated by transmitters in de-
energized cables that are disconnected on both ends. It allows users to find faults on direct-buried
power, telephone, cable, and sheathed tracer wire.
The EML accessory is designed to locate electronic markers on pipes and cables. It allows users to
find any standard electronic marker, used to mark specific locations for future locating.
The Live Power Adapter is intended to protect the transmitter from damage due to connection to live
electrical power.
The stethoscope accessory is used to identify lines in cabinets with multiple lines.
Only connections to safety certified devices are allowed (e.g. IEC 61010, UL/IEC 62368-1) with U B
port.
The system is designed for operation in temperatures typically experienced in earth moving and
construction work environments. Use in any other way is considered contrary to the intended use.

SAFETY
Guidelines
Follow these guidelines before operating any jobsite equipment:
• The CARLOC eries system should be operated only by persons familiar with its particular
characteristics and acquainted with the relevant safety procedures, otherwise the protection provided
by the equipment in this system may be impaired.
• Locally applying regulations have to be observed!
• Mark jobsite clearly and keep spectators away.
• Wear personal protective equipment.
• Review jobsite hazards, safety and emergency procedures, and individual responsibilities
with all personnel before work begins.
• Replace missing or damaged safety signs.
• Use equipment carefully. top operation and investigate anything that does not look or feel right.
• Contact your equipment dealer if you have any question about operation, maintenance, or
equipment use.
• Use genuine accessories to ensure system safety and reliable operation. The use of other parts
is not permitted and invalidates the warranty.

Safety Alert Classifications
These classifications and the icons defined on the following pages work together to alert you to
situations which could be harmful to you, jobsite bystanders or your equipment. When you see these
words and icons in the book or on the unit, carefully read and follow all instructions. YOUR AFETY
I AT TAKE.
Watch for the three safety alert levels: DANGER, WARN NG and CAUT ON. Learn what each level
means.
indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
indicates a potentially hazardous situation which, if not avoided, could result
in death or serious injury.
indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury.
Watch for two other words: NOTICE and MPORTANT.
NOTICE can keep you from doing something that might damage the unit or someone's property. It can
also alert you against unsafe practices.
MPORTANT can help you do a better job or make your job easier in some way.
Safety Alerts
Electric shock. Contacting electric lines will cause death or
serious injury. Know location of lines and stay away.
To help avoid injury:
• Do not use live power adapter unless you are properly qualified to work on
live power conductors.
• Check that equipment is in good condition and that test leads are clean and
have no cracked insulation.
• Have qualified utility personnel disconnect both ends of cable before working.
• Do not operate transmitter near explosive devices or blasting operations.
