5.6.1 REMOVAL OF THE OLD SENSOR-BATTERY PACK.

The 4 corner screws retaining the clear lid of the ONEO2 must be carefully unscrewed (posi-
drive screwdriver No.2) and the lid removed. On some models these screws may be
underneath covers. Using a fine flat bladed screw-driver the covers can gently lifted out to
reveal the screws. Take care to prevent scratching and damaging the lid.
The 4 screws holding the front plate must be unscrewed (posi-drive screwdriver No.1) and
removed. This will expose the PCB and provide access to the sensor and battery pack.
Do NOT pull on the wires of the lead.
Please note that the ONEO2 battery and sensor pack must not be disposed of in general
waste. They can be disposed of in battery recycling bins. Alternatively they can be returned
to Quantum Cryogenics for safe disposal and recycling (please contact QC for returns
authorisation number).
