Dispose of used batteries according to the local regulations of your
country.
End users within the European Union are obligated to return used bat-
teries (even ecologically compatible ones) to a collection point set up
for recycling purposes.
Batteries are marked with the crossed-out waste container symbol.
Therefore, they may not be disposed with the domestic waste.
5.2 Cleaning
Occasionally wipe the outside of the measuring instrument with a
damp, lint-free cloth. Disinfect the housing with isopropanol as re-
quired.
NOTE
The housing parts are made of plastic (polyurethane, ABS and
PMMA) and are only conditionally resistant against organic solvents.
Thus, avoid contact with acetone and similar detergents that contain
solvents. Remove any splashes immediately.
5.2.1 Cleaning the cell shaft
If liquid is in the cell shaft (e.g. due to a spilled cell), clean the cell shaft
as follows:
CAUTION
Cells can contain poisonous or corrosive substances. If the con-
tent is released follow the danger warnings on the cell. If neces-
sary, take corresponding protective measures (protective
goggles, protective gloves etc.).
2 If necessary, take four old batteries out of the battery
compartment.
3 Connect the cable of the rechargeable battery with the socket
(3) on the bottom of the battery compartment and insert the re-
chargeable battery in the battery compartment.
4 Close the battery compartment and fix it with the screws.
1 Switch the pHotoFlex
