NOTE: If a pulse rate alarm occurs while the PI
r
value is displayed, the alarm LED flashes
yellow. An alarm tone sounds unless alarms are silenced. Press the ComWheel to view
the pulse rate display.
Changing the line power filter
For the best low perfusion performance, set the line power filter to match the line power
frequency of your local AC power source. The software line power filter will then
eliminate potential interference when you use AC power or when you use battery power
near an AC power source.
When you power OFF the monitor, the line power filter setting (50 or 60) is displayed in
the high pulse rate alarm area.
1. To change the line power filter setting, power ON the monitor. Press the ComWheel
seven times, holding it in on the seventh press until the new setting is displayed: 50
H(z) or 60 H(z).
