Steps Required Before Drilling 1. Optimize and measure active interference. 2. Select frequency bands. 3. Pair the receiver with the transmitter. 4. Check for background noise. 5. Calibrate both bands. 6. Check Above Ground Range. Optimize and Measure Active Interference 1.

Select Frequency Bands 3. Click to move the selector to the band of your choice, hold briefly to select, then assign as either the Up or Down band (the band the Tx powers on with when facing Up or Up, Down, Cancel Down).
Check Above Ground Range (AGR) 11. Always check AGR with a tape measure to verify depth readings for both bands at various distances up to the maximum expected bore depth. Distance readings should be within ±5%. To access the AGR screen later, select Calibration, 1PT CAL, and wait 15 seconds for the AGR screen.

Changing Transmitter Frequency Band Switch between frequency bands during pre-bore calibration or mid-bore to overcome interference. A frequency band remains selected on both the receiver and transmitter even after a power cycle. Above Ground – Power-On Method Insert transmitter (Tx) batteries with the Tx pointing down (battery compartment on top, shown at right) to power on in the Down band.

FO results when the receiver is attenuating the Tx signal for depths shallower than 3 m. This is normal. See the operator's manual if the signal strength is flashing, indicating extreme interference. ® Watch our DigiTrak training videos at www.youtube.com/dcikent Printed: 8/22/2017...

Basic Locating 1. Find the FLP and RLP by centering the target ball in the box. 2. At the FLP, hold trigger for predicted depth reading. 3. Find the LL by centering the line in the box between the FLP and RLP (see Locate screen on previous page).
