Subsite TXu Original Instruction page 2

Install Batteries and
Select Frequency
1. Unscrew cap.
2. Check for and correct the
following conditions:
• dirty or damaged threads.
• missing, dirty or worn foam
washer on battery cap and
bottom of battery chamber.
• missing, worn or damaged
springs.
• missing, damaged or dirty
o-ring. Clean or replace as
needed.
3. Insert, positive end first, one Power Stick battery (p/
n 222-1369) or one Electrochem CC 3.67 V Lithium.
• To select 12 kHz frequency, hold beacon vertical
to the ground with the end slot pointed toward the
ground.
• To select 29 kHz frequency, hold beacon vertical
to the ground with the end slot pointing toward the
sky.
4. Install batteries. Keep beacon steady while hand
tightening cap firmly. Use tracker to confirm beacon
is functioning.
Note: Frequencies may be switched after they are
initially set. See "Switch Frequency While Drilling"
section.
IMPORTANT: For maximum performance, use only
Power Stick battery (p/n 222-1369) or Electrochem CC
3.67 V Lithium batteries. Standard "C" cell alkaline
batteries can cause intermittent operation and beacon
signal errors.
Test Operation
Use a tracker to test beacon function before leaving for
jobsite and after every battery change.
To test beacon function:
1. Turn on tracker, select frequency (if equipped with
dual frequency) and adjust gain so that signal
strength is approximately 50% (see tracker
operator's manual).
2. Roll beacon and look at display for corresponding
roll positions.
3. Tilt beacon and look at display for corresponding
pitch positions.
4. Check beacon battery status and temperature.
For best results, replace batteries daily. (Using weak
batteries in beacon can cause erratic signal and/or
damage.) Recalibrate tracker to beacon after changing
batteries.
Install Beacon into Tool Housing
The TXu beacon is designed to fit into all housings that
will accept a 1.25" (3.2 cm) diameter x 15" (38.1 cm)
length transmitter/beacon or larger. Some housings
require isolators or adapters. Refer to the appropriate
installation guide for each housing for proper installation.
IMPORTANT: Check beacon operation and condition of
both isolators (if used) before installing beacon into tool
housing.
1. Lay beacon into tool housing with end slot toward bit
and aligned with tab in the housing or lid.
2. Check for proper beacon alignment by rolling
housing on the ground and watching for
corresponding roll positions on tracker display.
IMPORTANT: After installing beacon into tool housing,
calibrate tracker for each frequency before drilling.
Calibrate Tracker to Beacon
1. Select beacon frequency.
2. Install beacon into drill head and place on ground
exactly 10' (3 m) away from tracker. Make sure no
metal objects including drilling unit and drill pipe are
within 20' (6 m) of tracker and toolhead.
3. Position tracker parallel to center of drill head.
4. Turn tracker on and enter the depth calibration
menu. See tracker manual for details.
5. Verify calibration by moving tracker 15' (4.5 m) away
from tool head. Check depth. If reading is not 15'
(4.5 m), recalibrate tracker.
IMPORTANT: When verifying calibration above
ground, be sure to stay in the calibration screen.
6. Repeat for other frequency.
Switch Frequency While Drilling
1. Allow beacon to go to sleep.
2. Rotate beacon within a minute of it going to sleep to
switch frequency.
If beacon is rotated after it has been asleep longer
than a minute, the frequency will not change.
3. Change and verify frequency on the tracker.
