3) Circuit Board Removal / Battery Replacement

The circuit board is mounted over two small plastic pillars and may be lifted away from the plastic base. Take extreme care when handling the circuit board as the electronic components may easily be damaged.

4) Re-assembly

Ensure that the battery is fitted correctly and then place the circuit board over the pillars in the bottom half of the case. The battery side of the circuit board must be towards the case.

Assemble both halves of the plastic case together making sure that the lug at the front of the case is located correctly. Push the silver clip back in place and test that the control operates by pressing either of the buttons and checking that the light in the centre illuminates.
