Operating Instructions
Communicating with the patient
Ensure that the Pure Sound II is turned on (check the red LED on the front panel) Fig 1.
Set the microphone volume dial to the mid-point (the dial cut out pointing vertically) Fig 2.
To test the volume of the microphone output, press the button on the microphone unit, when
the circuit is open to talk, an LED will light on the microphone base (Fig 3).
Talk at a normal volume to the patient and confirm that the level of the transmission is
acceptable. If not, adjust microphone volume up/down accordingly and retest.
Care must be taken to check that the microphone is not ‘open’ (e.g. transmitting to the
patient) when discussing anything that may be worrying, offensive or inappropriate. While the
LED illumination is a guide, it is not recommended that this be taken as a definitive guide and
that discretion is used at all times when a patient is being examined.
