Charles Machine Works Inc The 752TKR ユーザーズマニュアル

The 750/752 tracker has four operation modes: tracker control, 
walkover beacon tracking, remote guidance, and line locating. 
Tracker control, walkover beacon tracking and remote guidance 
work with 12K and 29K beacons.

Potential radio frequency (RF) 

hazard. Operating this device within 8” (20 cm) 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 8 dBl.

IMPORTANT: Large metal objects, rebar, power lines and any 
other kinds of interference can adversely affect depth estimates.

You must calibrate tracker to each beacon frequency before 
beginning a beacon tracking job. After calibration, tracker can 
estimate depths from approximately 9” (0.2 m) to 100’ (30.5 m) 
depending on beacon used. Keep the following in mind when 
calibrating system:

•

Beacon and tracker should not be moved or rotated until 
calibration is complete.

•

Only depth estimation is affected by calibration. Roll, pitch, 
left/right deviation, temperature, and battery status are not 
affected.

•

Large metal objects, rebar, power lines, and any other kinds of 
interference will adversely affect calibration.
