qualified personnel and only by following the instructions given in the
service manual.
This warning is stated on the product or in the operating instructions.
When replacing the lithium batteries, follow the note below.
Dispose of the used battery promptly. Keep away from children. Do
not disassemble and do not dispose of in fire.
The battery used in this device may present a fire or chemical hazard
if mistreated. Do not recharge, disassemble, heat above 100 ˚C or
incinerate. Replace only with the same Part Number. Use of another
battery may present a risk of fire or explosion.
Note: The lithium battery installation position is shown in the
exploded views.
ADVARSEL!
Lithiumbatteri − Eksplosionsfare ved
fejlagtig håndtering. Udskiftning må kun
ske med batteri af samme fabrikat og
type. Levér det brugte batteri tilbage til
leverandøren.
Denne advarsel or angivet på produktet eller i brugsvejledningen.
Ved udskiftning af lithium batterierne følges nedenstående
anveisning.
Batterierne må kun udskiftes med batterier af samme type og
mærke.
