Low Battery Alarm; Critical Battery Alarm; Power-Save Mode - Dräger Infinity M300 Series Instructions For Use Manual

System overview

Low battery alarm

When the battery power level has reached approximately 30 minutes of remaining charge, a Low battery
message is reported visually and acoustically at both the ICS and M300/M300+ to indicate that the battery
is low. The M300/M300+ displays the Low battery status once every three minutes, plus or minus five
seconds.

Critical battery alarm

The M300/M300+ displays a critical battery alarm message, Recharge battery, to indicate a low battery
when the M300/M300+ power level has reached approximately 15 minutes of remaining charge. The
alarm is reported visually and acoustically at both the M300/M300+ and the ICS. After the user
acknowledges the alarm, the message will rotate through any other displayed M300/M300+ messages.
NOTE
In the case of low or critical battery charge status, a message displays on the ICS and the M300/M300+,
as a reminder to recharge the battery. These status messages disappear and the annunciation stops
when the M300 is recharging in a Bedside Charger or Central Charger, or when the M300+ battery has
been replaced with a freshly charged battery.
For information on the indications of the battery status LED and charging the M300 battery, see page 94.

Power-save mode

Power-save mode is on by default. When power-save mode is off, the battery will drain faster. When
power-save mode is off, and the M300 is on the Bedside Charger, it is necessary to closely monitor the
battery charge level.
