PerkinElmer Photovac 2020 User manual

Warning: Limitation of Liability
The ultimate responsibility of the consequences of use of toxic
compounds rests with the user. PerkinElmer’s role is as a supplier of
instrumentation to assist in the early detection of hazardous
conditions involving such compounds.
2020 represents a major advance in this field and, as with all
complex instruments, it is vitally important to ensure that 2020 is
maintained in accordance with PerkinElmer’s instructions and that
proper calibration is regularly performed.
As with any complex device, 2020 is subject to failure and, while
PerkinElmer has taken, and continues to take, all possible
precautions to (a) reduce the possibility of failure, and (b) warn the
user in the event of failure, circumstances may occasionally occur in
which there is a failure despite such precautions on PerkinElmer’s
part. PerkinElmer regrets that it cannot accept liability for damages
of any kind caused as a result of either failure of the user to follow
instructions or of 2020 to perform.

MISE EN
GARDE
Afin de réduire les risques d’incendie et les blessures, lire et suivre
ces instructions:
1. Tout étalonnage, entretien et réparation de cet appareil, y
compris le chargement de la pile, doit être effectué dans
un endroit sûr, à l’écart des zones dangereuses.
2. N’utiliser que la pièce numéro MX350009 lorsqu’il faut
remplacer le bloc-pile.
3. Ne pas jeter la pile dans un feu. La cellule pourrait
exploser. Vérifier les codes locaux, qui peuvent comporter
des instructions de mise au rebut particulières.
4. Ne pas ouvrir et ne pas abîmer le bloc-pile.
5. Manipuler le bloc-pile avec soin, afin de ne pas court-
circuiter les bornes avec des matériels conducteurs tels
qu’une bague, un bracelet ou des clés. La pile ou le
conducteur pourraient surchauffer et causer des
brûlures.
6. Ne pas modifier l’orientation de la polarité appropriée
entre le bloc-pile et le chargeur.
7. Charger le bloc-pile fourni avec ou reconnu pour usage
avec ce produit seulement conformément aux instructions
et restrictions spécifiées dans ce manuel. Pour le
chargeur, n’utiliser que la pièce numéro MX350002 (115
