SEN0657 wind speed values

I am using the SEN0657 Ultrasonic 7-in-1 RS485 weather station.

The documentation states that the value in register 01F4 should be divided by 100 to get the speed in m/s - I have now been using this unit outside for a couple of weeks and the windspeed readings always appear to be around 10 times lower than weather forecast values.

Is there an error in the documentation - should the value be divided by 10?
