11. Instrument upgrade

In general, it is not necessary to perform an upgrade. If software updates are available, they
can be downloaded from our homepage: www.lovibond.com.

12. Returns

All instruments which are sent back to the manufacturer must be free from meas-
urement substance remains and other harmful substances. Measurement substance
remains on the housing or on the sensor can endanger persons or the environment.
Use suitable transport packaging for the return of the instrument, especially if it is still a
functioning instrument. Make sure that the instrument is protected with sufficient insulating
material in the packaging.

13. Disposal

Dispose of depleted batteries at a collection centre designated for this purpose.
The instrument may not be disposed of with the household waste. If the instrument needs
to be disposed of, send it directly to us (with sufficient postage paid). We shall dispose of the
equipment properly and in an environmentally friendly manner.
