Detectors in Close Proximity

•

On occasion it may be necessary to operate F3 detectors in close proximity.

In normal circumstances, an F3 detector can operate as close as 2 meters (7

feet) to a

nother F3 detector without suffering excessive mutual interference.

To achieve this minimum operating distance between detectors, Noise

Cancel is to be conducted as follows:

o With all other detectors switched off, switch on the first detector and

perform Noise Cancel.

o Once Noise Cancel is finished on the first detector, leave it switched

on and switch on the second detector (at least 2 meters away) and

conduct a Noise Cancel procedure with the second detector.



Continue this process for all detectors being used in close proximity.

Piece before switching off to ensure satisfactory performance before being

packed away. Once completed:

o Turn the detector off.

o Clean the detector and inspect for any signs of damage.

o Retract the middle and lower shafts (if necessary).

o Disconnect the Earset.

Remove the batteries from the Battery Pack and stow in the Hard
