Calibration
Use the Calibration menu to calibrate the receiver to a transmitter. Calibration is required
prior to first-time use and before using a different transmitter, receiver, drill head, or
transmitter band.
Calibrate each band separately
If you select an optimized band that has not been calibrated yet, appears in the roll
indicator. Calibrate separately for each optimized frequency band prior to each job.
Calibration affects depth readings, but not roll/pitch.
Do not calibrate if:
 You are within 10 ft. of metal structures, such as steel pipe, chain-link fence, metal siding,
construction equipment, automobiles, etc.
 The receiver is over rebar or underground utilities.
 The receiver is in the vicinity of excessive interference, as shown by
high background noise readings on the frequency optimizer graph,
or an A (Attenuation) at the bottom left of the graph. Also, the
receiver will not allow calibration with a flashing red signal strength
value on the locate screen or a flashing red A at the top right of the
roll indicator.
 The receiver is not displaying transmitter data.
 The signal strength from the transmitter is less than 300 points (too
low) or greater than 950 points (too high). Outside this range, a
calibration failure screen will indicate low or high signal strength (see
step 6 on page 17). Check your setup and try again.

The transmitter must be installed in a drill head during calibration.
During calibration, Height-Above-Ground (HAG) is automatically turned off. After
calibration, HAG must be turned back on manually.

1-Point Calibration
This is the most common method of calibrating depth readings and is accomplished above
ground, prior to drilling.
1. Place the receiver and the transmitter (in a drill head) parallel to each other on level
ground, with both devices powered on.
2. With the receiver at the Locate screen, verify that roll and pitch values are being
displayed and that a steady signal is being received from the transmitter. The transmit-
ter’s signal strength at calibration is available under View calibration. A change in signal
strength later can indicate you are currently in an interference environment or there is a
problem with your equipment.
3. Move the locator within 2 ft. of the transmitter to enable signal attenuation, indicated by
an A at the top right of the roll indicator. Move the locator back to 10 ft. away and verify
