9.2.1 Care of batteries
Warning!
An alternative ventilation option (e.g. a replacement device or manual ventilating
bag) must be used during maintenance of the internal battery for patients
dependent on a ventilation device. The internal battery may not be maintained with
patient ventilation in progress.
To prolong the life of your batteries, we recommend the measures below:
• Run down the battery completely every 6 to 12 months by running the device
without a power cable using the red test adapter until the device switches to the
internal battery/switches off and then recharge the battery completely. This
increases the accuracy of the capacity display. You should also observe the
maintenance intervals for the internal battery (see “9.1.3 Internal battery” on
page 96) and the replaceable battery (see “9.1.4 Replaceable battery (if
present)” on page 96).
Note
When the device is being operated with the red test adapter, alarms may occur as
a function of device settings (see “8.2 Alarms” on page 83).
