 WARNING 
z  When the alarm sound is switched off, the patient monitor will give no audible 
alarm tones even if a new alarm occurs. Therefore the user should be very careful 
about whether to switch off the alarm sound or not. 
z  Do not rely exclusively on the audible alarm system for patient monitoring. 
Adjustment of alarm volume to a low level may result in a hazard to the patient. 
Always keep the patient under close surveillance.
