internal batteries is carried out. Independent of this, the battery test must be carried out every

, as well as after changing the single batteries (art. no. 1600 0015). The test takes max.
4 hours.
For the battery test a tube system or other accessories must not be connected to the device.
Carry out the battery test as follows.
1. Connect the device to the mains power.

8. After the PIN code has been entered, the battery test, which consists of two phases, will start:
a. Phase 1: Battery is charged (max. 3 h depending on the battery’s charge status)
b. Phase 2: Battery is discharged with a constant load (approx. 1 h)
The display indicates the progress of the battery test as a percentage.
After the 2nd phase has ended, the capacity of the battery is displayed. If the capacity is
≥
80 %, the test is considered to be passed. If the capacity is lower or the message “ERROR”
is displayed in the status screen, both batteries or the entire battery pack must be replaced.
