NOTE
Please pay attention to the following when using lithium batteries:
The type-specific discharge behaviour of lithium batteries (considerable
voltage drop at the end of the life time) may cause that a low battery is indicated
at the terminal only for a short period or not at all.
This may cause a short-term malfunction of the terminal.
We recommend changing the batteries before the winter months with the
outdoor version.
