°
C to 40
°
C, 20%

2
20mm button cell type 2032. Exhausted cells must be disposed of carefully in
accordance with local regulations; do not cut open, incinerate, expose to temperatures above 60°C
or attempt to recharge.
Do not wet the instrument when cleaning it and in particular use only a soft dry cloth to clean the
