Magnets should not be allowed near the R-Series Detectors (no closer than a foot or

so), and never in the central tunnel.

The Diverter Gate should be thoroughly rinsed, paying special attention to the

hollow doors and the underside of the doors and beaks, which can accumulate a

considerable amount of fish slime. The bumpers on the gate doors may ”glue”

shut with fish slime or after periods of no use. Carefully “peel” the bumpers away

from the gate beak before you use the gate.

The gate is very sturdy, but it should be handled carefully to avoid bending. In

particular, the door latches require precise alignment and this can be ruined if the

unit is bent.

The R-Series detector and gate are shipped with a 12-volt DC sealed lead acid

battery and a battery charger. Recharge your 12-volt battery as needed

(instructions are with the battery charger). Disconnect the battery from the

detector or gate when not in use or when charging.

Part 6: Troubleshooting

Sensitivity Adjustment

Several situations affect the ability of the R-Series Detector to function properly.

Stray magnetic fields around the detector, movement of the entire detector in the

form of wobble or vibration, and flexing of the central tube slightly by forcing fish

into it or having live fish slap it hard all create magnetic fields which can cause

false positives. Magnetic sand and dirt particles will also affect reliability.

Stray magnetic fields are initially difficult to judge, but once seen by the

operator of the detector, will be obvious. If the detector sensitivity is normally set

at about 11:00 o'clock, to attain the 2

and sometimes 3

LED setting, but it is

suddenly necessary to turn down the sensitivity to achieve the same display

when at a new location or the same location with new equipment around, there is

probably equipment in the vicinity causing strong magnetic fields. This will

generate a moving magnetic field, similar to that of a tag. Depending on the

severity, it may be necessary to move either the detection equipment or the

offending electrical equipment or reroute electrical cables. Someone working
