Weak wireless connection or repeated drop-outs (expected range 3-5 metres within line of sight)
Move closer to the Transceiver Dongle
Obtain a USB male - USB female extension cable and plug into the PC. Attach the
Transceiver Dongle to the extension cable and position in a prominent location away from
your PC, monitor, wireless router and other sources of radio-frequency interference.
Turn off or disconnect other wireless and Bluetooth devices in the area to isolate possible
causes
Turn off neuroheadset, unplug Transceiver Dongle and repeat the pairing exercise
Sensors do not positively lock in place (sensors should click in place as they are rotated a quarter-
turn clockwise after insertion into the socket)
Sensors are made deliberately tight to start with and the locking tabs are slightly deformed
to the correct shape during the first fitting. Soetimes the sensors are very tight and the user
feels they will not turn further into the socket.
Take each sensor in turn and use an empty socket in the Hydrator Pack. Forcibly rotate the
sensor fully clockwise in the socket until a definite click is felt (use a cloth or tool to hold the
sensor if your fingers are easily damaged). Click and unclick the sensor into the socket a
few times to complete the process.
The sensor can now be fitted to the headset, Make sure ou feel a distinct catch as ou rotate
the sensor into the socket and the finger tabs are aligned along the axis of each arm.
All sensors black except RED references (directly below ears on Contact Quality map)
Start with RUBBER COMFORT PADS in locations directly behind the ears.
The primary reference sensor locations are behind the head, elevated at about 30 degrees
backwards behind the ears (see diagram in main section of this manual)
Ensure reference sensors and at least one forehead sensor are sufficiently wet
Ensure all sensors are properly located in the neuroheadset receptacles. They should not
spin or fall out when gently moved.
