Figure 22. Audio Reset

NOTE

If the Audio Reset button is held too long, the detector will

commence the Ground Balance procedure.

Noise Cancel and Audio Reset procedures can be performed at any

time the Threshold Tone becomes noisy, uneven, or rises in volume.

Once Noise Cancel or Audio Reset is complete, continue with steps

2 and 3. Figure 23 illustrates this sequence. Once completed, the

F3 can commence operations in compliance with local Standard

Operating Procedures.

Having completed STEPS 1, 2 and 3 the F3 remembers the Ground

Balance setting even after the detector has been switched off.

After Noise Cancel is completed the F3 remembers the frequency

selected to minimise interference, even if the detector is switched

off.
