Removing the Batteries
Batteries should be removed when the MX40 is not in use or is being stored.
To remove the batteries, open the battery compartment door and push from
the opening at the bottom of the compartment to pop the batteries out. To
remove the rechargeable battery, open the battery compartment door and
lift up on the raised tab on the battery to release it from the battery
compartment. Device settings (patient cable type, SpO
2 mode, volume, etc.)
are retained when the batteries are removed.
Important— Do not use AA batteries that have different energy levels
remaining. Fresh AA batteries are recommended for each new
application.
Caution
Do not "store" disposable AA batteries by leaving them in the incorrect
polarity position in the MX40.
Be careful not to short circuit the batteries. Batteries can get hot when
shorted. Short circuits are caused when a piece of metal touches both the
positive and negative terminals simultaneously. More than a momentary
short circuit will generally reduce the battery life. In case of a short circuit,
discard the batteries, or just the shorted one if the batteries are new.
Failure to remove the rechargeable battery from the MX40 when the device
is not in use may result in damage to the battery, including reduced
capacity, inaccurate charge status indicator, failure to charge, and failure to
function in the MX40.
Disposal of Batteries
When disposing of batteries, follow local laws for proper disposal. Dispose
of batteries in approved containers. If local regulations require you to
recycle batteries, recycle batteries in accordance with those regulations.
