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
Frequency Optimizer
(FO) from the Main
menu. The FO will show active interference (noise) readings for nine
frequency bands.
1. Maximum noise reading
2. Noise
3. Attenuation in effect
4. Band number
5. Selector
6. Pair
7. Exit
Frequency Optimization Results
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. Then
select Exit and restart FO at this point to perform a new scan and select and
pair a second band for use in this higher-interference area.
Your receiver can only detect active interference, not passive interference.
Lower frequency bands tend to perform well despite passive interference.
Middle bands can perform better in deeper bores and may have longer Target
Steering capability. High bands have slightly less signal strength but tend to
offer better performance around active interference such as power lines.
