Battery Handling
Batteries, rechargeable or not, should not be disposed
of into ordinary household waste. Instead, they must be
recycled properly to protect the environment and cut down
the waste of precious resources.
Your local waste management authority can supply details
concerning the proper disposal of batteries.
In compliance with the EU Directive 2006/66/EC, the
button cell battery located on the printed circuit board
inside the product, can be removed at the end of the
product life, by professional personnel only.
Step 8: Changing the Batteries
How do I know when to change
the batteries?
When the batteries start to run low a battery icon will
flash in the display to indicate “low battery”, during
this time the MiStat will function normally. When
the battery icon alone is shown in the display, the
batteries are completely exhausted and the MiStat will
cease to function (see below). Re-activate by replacing
the batteries.
How to replace the batteries
Remove the battery covers as shown. Replace the
batteries with 2 x 1.5V IEC LR6 (AA) Alkaline batteries
ensuring correct orientation. Replace the battery
covers pressing fully home.
