Changing Transmitter Frequency Band
Switch between Up and Down bands during pre-bore calibration
or mid-bore to overcome interference. See next page to change
bands on the locator.
Both optimized bands remain stored on both the locator 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. Insert batteries with the Tx pointing up to power on
in the Up band.
Above Ground – Tilt Method
You must hold the Tx at the same general clock position
(±2 CP) for this whole procedure. Hold Tx powered on at level
(0±10°) for at least five seconds (sec.). Tilt Tx up at approx. +65°
(almost vertical) for 10–18 sec., then return to level for 10–18 sec.
When the Tx changes bands, data disappears from the locator.
Below Ground (Mid-Bore) – 10/2/7 Roll Method
Disable Roll Offset (if enabled).
1. Roll clock-wise to
approx. 10 o'clock ± 1 CP.
Wait 10-18 seconds.
2. Roll clock-wise to
approx. 2 o'clock ± 1 CP.
Wait 10-18 seconds
3. Roll clock-wise to
approx. 7 o'clock ± 1 CP.
Wait 10-18 seconds.
Data should disappear in 10-15 seconds. Re-enable Roll Offset, if needed.
The Aurora display has a built-in app that can walk you through this
method. See the
DCI DigiGuide App
for more details.
Below Ground (Mid-Bore) – RRS3 Roll Method
Remain at any clock position for at least 40 seconds (sec.) to clear timers.
Complete one full clock-wise rotation (±2 CP) within 1–30 sec., wait 10-18
sec., and repeat this sequence twice more for a total of three rotations.
After 60 sec. the Tx should change frequency band and the locator will
stop receiving data and depth. The Aurora display has a built-in app that
can walk you through this method. See the
DCI DigiGuide App
for more
details.
