12. Firmware update
A firmware update for the main controller of the WS 300 PC-US can be
started with the provided software via the USB interface of the weather
station.
- Start the Update program (Menu "Tools", Menu point "Firmware up-
date") in the "Weather Prof 2007" program and follow the program in-
structions.
If the update procedure is started by accident, it can be
aborted right up until step 5.
If the update mode has also been activated on the device
according to the instructions from the software, the weather
station must be separated from the USB for a few seconds
and the batteries are to be removed from the device.
The function of the device is not affected in this case, it
continues to work with the previous firmware after starting
operation again.
Depending on which batteries or rechargeable bat-
teries you use, the interval for changing them is dif-
ferent. High quality alkaline batteries are longer last-
ing, rechargeable batteries or cheap zinc-carbon
batteries must be changed much more often.

The low-battery symbol appears on the display (
), the batteries are
to be replaced with new ones.
To avoid losing any data in this case, the WS 300 PC-US should be con-
nected with the running PC via the USB cable while changing batteries.
• Always replace the complete set of batteries.
• Do not mix full with "half-full" batteries.
• Always use batteries of the same type and the same manufacturer.
