REMARKS!
For a long operating time, the use of commercially branded batteries is recommended.
When all battery symbols (see also section  6.4) on the LCD display are extinguished,
the battery should be changed as soon as possible.
When changing the battery, be sure to observe the polarity. Refer to the markings on the
battery case!
When the battery is changed, all data and parameters are retained (apart from the current
actual value).
The included quality battery enables the HWD15 to operate continuously for up to 12 months. The status of the
battery is shown on the LCD display.
On the front side (below the hollow shaft) there is the battery case, which can be opened without tools by gently
pressing it together and pulling it out. Please pay attention to the polarity mark (+) when inserting the battery.
