Changing Transmitter Frequency or Mode
For models with dual frequencies or XRange
Install transmitter (Tx) batteries with opposite end of Tx pointing up
to select high frequency or down for lower frequency.
1. Disable Roll Offset (if enabled).
2. Change Tx frequency or turn XRange mode on/off:
Above Ground (Pre-Bore) Tilt Method:
Frequency Change: Let Tx sit at level (0±10°) for
at least five seconds (sec.), tilt Tx up at approx.
+65° for 10–18 sec., then return to level for 10–18
sec., maintaining ±2 clock positions (CP) during
this sequence.
XRange Mode On/Off: Same as above, but use approx. -65°
pitch and maintain constant 12 o'clock CP.
Below Ground (Mid-Bore) Methods:
Frequency Change 10-2-7: Roll the Tx clockwise (CW) to a
CP of 10±1 and wait 10–18 sec., slowly roll CW to CP 2±1
and wait 10-18 sec., and slowly roll CW to CP 7±1. Tx
changes frequency within 20 sec.
Frequency Change RRS
: Remain at any CP for at least 40
sec to clear timers. Complete one full CW rotation (±2 CP)
within 1–30 sec., wait 10-18 sec, and repeat twice for a total of
three rotations (RRS3). Tx changes frequency within 60 sec.
XRange Mode On/Off RRS
1
: Same as frequency change
RRS above but a total of four rotations (RRS4).
3. At the Locate screen, hold toggle right
to open the Tx Shortcut menu.
4. Select appropriate Tx frequency and
toggle XRange on/off, then select
to return to the Locate screen.
5. Re-enable Roll Offset if applicable.
