When inserting and changing batteries, pay
attention to the correct polarity (+/-).
Do not subject the batteries to extreme
conditions by, for example, storing them on
heaters or under direct sunlight. Increased
risk of leakage!
Clean the battery and device contacts, as
needed, before inserting the battery.
Only insert batteries of the same type; do not
use different types or used and new batteries
with each other.
Do not make any modifications to the item.
Only allow repairs to be carried out at a
specialist workshop. Repairs carried out
incorrectly can considerably endanger the
user.
