Before any maintenance or cleaning is undertaken, it is important that the mains cable is
removed from the wall socket, isolating the unit from any power.
The equipment can also be isolated from the mains by removing the mains cable from the
instrument.
Inspect the equipment casings and all cables before use.
If any damage is found the equipment should not be used before it has been inspected by a
competent person.
Particular attention should be paid to the mains cable at the back of the instrument and the
cable of the patient response button.
