Calibration
To maintain the accuracy of the breathalyzer, ACE Instruments
recommends a calibration after 500 tests or approx. every 12
months (depending which incident happens first). For a calibra-
tion service you can send the device to ACE Instruments (see
www.ace-technik.com). The calibration is not mandatory, but the
accuracy of the breathalyzer will decrease steadily and additio-
nally the warranty for the sensor expires.
We recommend sending it as a parcel, so that in case of
loss an inquiry or proof of delivery is possible.
Due to changes in the product, the procedures stated can
change. This can take place without prior notice or adaptation
of the operating manual and is no cause for complaint, return
or price reduction. The user is responsible for recognizing
discrepancies between the operating manual and the actual
handling of the ACE Instruments a Breathalyzer and must react
accordingly.
Battery Notices
The device associated with this operating manual contains 2
AAA Alkaline batteries (1.5 V). These batteries are non-rechar-
geable. The use of a rechargeable battery is not possible with
this device and can damage it. If the included batteries are
depleted, they must not be thrown away into household waste.
Used batteries may contain harmful substances that can cause
damage to the environment or your health. Please return all
depleted batteries to electrical appliance stores, who collect
them for free.
Battery exchange
To replace the batteries, push the battery cover on the rear of
the unit downwards and replace the discharged batteries with
new ones. Be aware of the polarity when inserting the batteries
(+/- pole). Close the battery compartment cover again. In the EU,
the return of used batteries is mandatory by law. All depleted
and rechargeable batteries will be recycled. This way valuable
resources like iron, zinc and nickel can be retrieved and reused.
Battery recycling is the easiest lesson in environmental protec-
tion – so please support it!
The shown garbage bins mean that batteries or rechargeable
batteries must not be thrown into the household waste.
