Operating Modes 4-17
• Do not store batteries in the MX40 in a reverse polarity position. This
can cause leakage and corrode the battery terminal. This corrosion can
create a short in the battery adapter which can cause the batteries to
overheat.
• If battery leakage should occur, use caution in removing the battery.
The leaked substance may cause eye or skin irritation. Avoid contact
with skin. Wash hands. Replace the battery tray if exposed to battery
leakage. Continued use increases the risk of batteries shorting and
overheating, potentially resulting in burns to the user.
• To eliminate the risk of electrical shock or burn, do not carry loose
batteries on your person, e.g. in clothing pockets.
• Use of AA Lithium batteries or batteries with terminal voltage >1.6V
may cause damage to the device.
Caution
• When monitoring with the WLAN version of the MX40 (Model 865352),
the lithium-ion rechargeable battery is the only approved power source.
Use of AA disposable batteries is not supported.
Lithium-ion Rechargeable Battery Care
Care of the rechargeable battery begins when you receive a new battery for
use and continues throughout the life of the battery. The table below lists
battery care activities and when they should be performed.
Activity When to Perform
Perform a visual inspection. Before inserting a battery in the MX40.
Charge the battery. Upon receipt, after use, or if a low battery
state is indicated. To optimize
performance, a fully (or almost fully)
discharged battery should be charged as
soon as possible.
Clean the battery At each patient discharge, or in cases
when the battery is exposed to
contaminants.
Charge stored batteries to at least 90% of
their capacity every six months.
When not in use for an extended period
of time.
