WARNING
• When adjusting alarm volume, ensure that the alarm can be heard above the ambient noise
levels that the patient may experience in a variety of settings, including use in noisy
environments or inside mobility bags.
In the example below, your Clinician has maintained the default alarm volume of three. This means the
'1' and '2' volume options are disabled and you are free to increase and decrease the alarm Volume
levels between '3' and '5'. If however, your Clinician had set the minumum volume level at '1', all
volume options would be available for selection.
