Battery Replacement - Welch Allyn 53000 Directions For Use Manual

72 Chapter 7 Reference
Battery failure causes the immediate suspension of all monitoring and print functions. If
the wall charger is not plugged in, then the monitor shuts off 15 minutes after the battery
discharge reaches failure level. If automatic NIBP is selected, and if the wall charger is
plugged in before the monitor shuts down, then automatic measurement cycles resume
as soon as the battery voltage rises above the failure threshold.

Battery Replacement

When the battery has reached end of life, replace it with an identical battery from Welch
Allyn (reorder number 501-0015-XX).
Caution Always recycle batteries according to local regulations. Never dispose
of batteries in waste receptacles.
