Steps Required Before Drilling
1.
Optimize and measure active interference.
2.
Select frequency bands.
3.
Pair the receiver with the transmitter.
4.
Check for background noise.
5.
Calibrate both bands.
6.
Check Above Ground Range.
Optimize and Measure Active Interference
1. With the transmitter off, select Transmitter selection from the Main
menu, then Frequency Optimization (FO). The FO will show active
interference (noise) readings for nine optimized bands.
1. Maximum noise reading
2. Up band
3. Down band
4. Noise
5. Band number
6. Selector
7. Pair
8. Exit
Frequency Optimization Results
Run the FO for each new project because it selects an optimal set of
frequencies for each band every time.
2.
With the FO results displayed, walk the receiver along the bore path
while observing the noise readings and mark those points where
significant changes occur.
If noise levels rise substantially at any point along the bore, consider
selecting and pairing one band (see next step) that performed well up
to this point. Select Exit and restart FO at this point to perform a new
scan, then select and pair a second band for use in this higher-
interference area.
