Intended Use
CMW
Intended Use
The 830R receiver is designed to locate buried pipes and cables at an 83.0775 kHz frequency. Optional
passive power and cathodic protection frequencies (60, 120, and 180 Hz in North America; 50, 100, and
150 Hz in other locations) are available.
The 830T transmitter places a single 83.0775 kHz signal on a target cable to be detected by an 830R
receiver. The transmitter places a signal on the cable through either direct connection, inductive clamping,
or induction (broadcast) modes.
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. The
830R/T system should be operated only by persons familiar with its particular characteristics and
acquainted with the relevant safety procedures. The system should be serviced only by Ditch Witch repair
centers.

FCC Statement
CMW
FCC Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by The Charles Machine Works, Inc. could void the
user’s authority to operate the equipment.
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
operator’s 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.
IEC Safety Definitions
Hazardous voltage--electrical shock or equipment damage can result if transmitter is connected to
live cable. Have qualified utility personnel disconnect both ends of cable before working.
IEC protection class II or double insulated electrical device is one which has been designed in
such a way that it does not require a safety connection to electrical ground. In a device of this
class, no single failure can result in dangerous voltage becoming exposed so that it might cause
an electrical shock. This characteristic must be achieved without relying on a grounded metal
casing.
