Safety Precautions
and Warnings (Continued)
 The battery charger provided with the DigiTrak F2 system is designed with adequate safeguards to
protect you from shock and other hazards when used as specified within this document. If you use
the battery charger in a manner not specified by this document, the protection provided may be
impaired. Do not attempt to disassemble the battery charger. It contains no user-serviceable parts.
The battery charger is not to be installed into caravans, recreational vehicles, or similar vehicles
 Remove the batteries from all components of the system during shipping and prolonged storage.
 Prior to the start of each drilling run, test the DigiTrak F2 system with the transmitter inside the drill
head to confirm that it is operating properly and is providing accurate drill head location and heading
information (see the Receiver and Locating sections) and accurate transmitter depth, pitch, and roll
information.
 During drilling, the depth will not be accurate unless:
• The receiver has been properly calibrated and the calibration has been checked for accuracy so
that the receiver shows the correct depth.
• The transmitter has been located correctly and accurately and the receiver is directly above the
transmitter in the drill head underground.
• The receiver is kept level and the height-above-ground has been set correctly.
 Always test calibration after you have stopped drilling for any length of time.
 Interference can cause inaccuracies in the measurement of depth and loss of the transmitter’s pitch,
roll, or heading. You should always perform an electrical interference check prior to drilling.
• Sources of interference include but are not limited to traffic signal loops, invisible dog fences,
cable TV, power lines, fiber-trace lines, metal structures, cathodic protection, telephone lines, cell
phones, transmission towers, conductive earth, salt water, rebar, radio frequencies, and other
unknown sources of interference.
• Interference with the operation of the remote display may also occur from other sources operating
nearby on the same frequency, such as car rental agencies using their remote check-in modules,
other directional drilling locating equipment, etc.
• Background noise must be minimal and signal strength must be at least 150 points above the
background noise during all locating operations.
 Carefully review this manual to ensure you know how to operate the DigiTrak F2 system properly to
obtain accurate depth, pitch, roll, and locate points. If you have any questions about the operation of
the system, please call DCI’s Customer Service Department at any of the phone numbers provided
on the cover, and we will do our best to assist you.
