Charles Machine Works Inc The 8500TKR ユーザーズマニュアル

The tracker has two modes: walkover location and drill-thru. Use walkover location mode to find position of 
the beacon. Once tracker is in or near the beacon plane, select the depth view to determine the depth and 
the left/right offset. With tracker in front of and parallel to beacon, press the L/R button while in the main 
locate view to see the projected path of the beacon. In drill-thru mode, the tracker is placed along the 
intended bore path and provides the necessary steering corrections for the drilling unit operator to drill that 
path.

1.

Install battery in beacon.

2.

Potential radio frequency (RF) hazard. Operating this device within 4” 

(100 mm) of your body may cause RF exposure levels to exceed FCC RF exposure limits 
and should be avoided.

•

This device must not be co-located with any other radio transmitter. 

•

The maximum antenna gain is 2.5 dBi.

•

Error conditions will be reported onscreen below diagram.

•

Pressing “clear” button will restore factory default. This will not provide accurate depth and 
offset measurements. Calibrate beacon and tracker properly.

•

Pressing “cancel” will exit calibration menu without changing tracker’s calibration.

•

If using a dual-frequency beacon, calibrate both frequencies.
