Important safety instructions
When using your telephone equipment, basic safety precautions should always be followed to reduce the risk of re, electric shock
and injury, including the following:
1. This product should be installed by a qualied technician.
2. This product should only be connected to the host equipment and never directly to the network such as Public Switch Telephone
Network (PSTN) or Plain Old Telephone Services (POTS).
3. Read and understand all instructions.
4. Follow all warnings and instructions marked on the product.
5. Unplug this product from the wall outlet before cleaning. Do not use liquid or aerosol cleaners. Use a damp cloth for cleaning.
6. Do not use this product near water such as near a bath tub, wash bowl, kitchen sink, laundry tub or swimming pool, or in a wet
basement or shower.
7. Do not place this product on an unstable table, shelf, stand or other unstable surfaces.
8. Slots and openings in the back or bottom of the telephone base and handset are provided for ventilation. To protect them from
overheating, these openings must not be blocked by placing the product on a soft surface such as a bed, sofa or rug. This
product should never be placed near or over a radiator or heat register. This product should not be placed in any area where
proper ventilation is not provided.
9. This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the
type of power supply on the premises, consult your dealer or local power company.
10. Do not allow anything to rest on the power cord. Do not install this product where the cord may be walked on.
11. Never push objects of any kind into this product through the slots in the telephone base or handset because they may touch
dangerous voltage points or create a short circuit. Never spill liquid of any kind on the product.
12. To reduce the risk of electric shock, do not disassemble this product, but take it to an authorized service facility. Opening or
removing parts of the telephone base or handset other than specied access doors may expose you to dangerous voltages or
other risks. Incorrect reassembling can cause electric shock when the product is subsequently used.
13. Do not overload wall outlets and extension cords.
14. Unplug this product from the wall outlet and refer servicing to an authorized service facility under the following conditions:
• When the power supply cord or plug is damaged or frayed.
• If liquid has been spilled onto the product.
• If the product has been exposed to rain or water.
• If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by
the operation instructions. Improper adjustment of other controls may result in damage and often requires extensive work by
an authorized technician to restore the product to normal operation.
• If the product has been dropped and the telephone base and/or handset has been damaged.
• If the product exhibits a distinct change in performance.
15. Avoid using a telephone (other than cordless) during an electrical storm. There is a remote risk of electric shock from lightning.
16. Do not use the telephone to report a gas leak in the vicinity of the leak. Under certain circumstances, a spark may be created
when the adapter is plugged into the power outlet, or when the handset is replaced in its cradle. This is a common event
associated with the closing of any electrical circuit. The user should not plug the phone into a power outlet, and should not put
a charged handset into the cradle, if the phone is located in an environment containing concentrations of ammable or ame-
supporting gases, unless there is adequate ventilation. A spark in such an environment could create a re or explosion. Such
environments might include: medical use of oxygen without adequate ventilation; industrial gases (cleaning solvents; gasoline
vapors; etc.); a leak of natural gas; etc.
17. Only put the handset of your telephone next to your ear when it is in normal talk mode.
18. The power adapters are intended to be correctly oriented in a vertical or oor mount position. The prongs are not designed to
hold the plug in place if it is plugged into a ceiling, under-the-table or cabinet outlet.
19. For pluggable equipment, the socket-outlet (power adapter) shall be installed near the equipment and shall be easily accessible.
20. Use only the power cord and batteries indicated in this manual. Do not dispose of batteries in a re. They may explode. Check
with local codes for possible special disposal instructions.
21. In wall mounting position, make sure to mount the telephone base on the wall by aligning the eyelets with the mounting studs of
the wall plate. Then slide the telephone base down on both mounting studs until it locks into place. Refer to the full instructions
in Installation in the user’s manual.
22. CAUTION: Keep small metallic objects such as pins and staples away from the handset receiver.
23. CAUTION: There may be a risk of explosion if a wrong type of handset battery is used (A2410, A2420, C4100, C4200,
CTM-A241HS, CTM-A241SD, CTM-A242HS, CTM-A242SD, CTM-A2411, CTM-A2411-BATT, CTM-A2421, CTM-A2421-
BATT, CTM-A2510, CTM-A2510-USB, CTM-C4101 and CTM-C4201). Use only the supplied rechargeable battery (BT264392/
BT266342) or replacement battery (BT266342). Dispose of used batteries according to the information in The RBRC®seal in
the user’s manual.
SAVE THESE INSTRUCTIONS

Mesures de sécurité importantes
Afin de réduire les risques d’incendie, de blessures corporelles ou d’électrocution, suivez toujours ces mesures préventives de base
lorsque vous utilisez votre téléphone:
1. Cet appareil doit être installé par un technicien qualifié.
2. Cet appareil doit être branché à un équipement hôte et jamais branché à un réseau, tel qu’un réseau PSTN publique ou un réseau
téléphonique standard (POTS).
3. Lisez et comprenez bien toutes les instructions.
4. Observez toutes les instructions et mises en garde inscrites sur l’appareil.
5. Débranchez ce téléphone de la prise murale avant de le nettoyer. N’utilisez pas de nettoyeurs liquides ni en aérosol. N’utilisez
qu’un chiffon doux et légèrement humecté.
6. N’utilisez pas ce produit près de l’eau, tel que près d’un bain, d’un lavabo, d’un évier de cuisine, d’un bac de lavage ou d’une
piscine, ou dans un sous-sol humide ou sous la douche.
7. Ne déposez pas ce téléphone sur un chariot, support ou table chancelants. L’appareil pourrait tomber et être sérieusement
endommagé.
8. Le boîtier de l’appareil est doté de fentes et d’ouvertures d’aération situées à l’arrière ou en dessous. Afin d’empêcher la
surchauffe, ces ouvertures ne doivent pas être obstruées en plaçant l’appareil sur un lit, divan, tapis ou autre surface similaires.
Ne placez pas cet appareil à proximité d’un élément de chauffage ni d’une plinthe électrique. De plus, ne l’installez pas dans une
unité murale ou un cabinet fermé qui ne possède pas d’aération adéquate.
9. Ne faites fonctionner cet appareil qu’avec le type d’alimentation indiqué sur les étiquettes de l’appareil. Si vous ne connaissez pas
le voltage de votre maison, consultez votre marchand ou votre fournisseur d’électricité.
10. Ne déposez rien sur le cordon d’alimentation. Installez cet appareil dans un endroit sécuritaire, là où personne ne pourra trébucher
sur la ligne d’alimentation ni le cordon téléphonique modulaire.
11. N’insérez jamais d’objets à travers les fentes et ouvertures de cet appareil, car ils pourraient toucher à des points de tension
dangereux ou court-circuiter des pièces, ce qui constituerait un risque d’incendie ou d’électrocution. N’échappez pas de liquides
dans l’appareil.
12. Afin de réduire les risques d’électrocution, ne démontez pas l’appareil, mais apportez-le plutôt à un centre de service qualifié
s’il doit être réparé. En enlevant le couvercle, vous vous exposez à des tensions dangereuses ou autres dangers similaires. Un
remontage inadéquat peut être à l’origine d’une électrocution lors d’une utilisation ultérieure de l’appareil.
13. Ne surchargez pas les prises de courant ni les rallonges électriques, car ceci peut constituer un risque d’incendie ou
d’électrocution.
14. Unplug this product from the wall outlet and refer servicing to an authorized service facility under the following conditions:
• Lorsque le cordon d’alimentation est endommagé ou écorché.
• Si du liquide a été échappé dans l’appareil.
• Si l’appareil a été exposé à une source d’humidité telle que la pluie ou l’eau.
• Si l’appareil ne fonctionne pas normalement en suivant les directives du guide. N’ajustez que les commandes couvertes dans le
guide d’utilisation, car un mauvais réglage de celles-ci peut être à l’origine de dommages, ce qui nécessiterait des réparations
considérables pour remettre l’appareil à son état de fonctionnement normal.
• Si l’appareil a été échappé ou son boîtier, endommagé.
• Si le produit affiche une nette diminution de sa performance.
15. Évitez d’utiliser un téléphone (autre qu’un sans fil) pendant un orage. Les éclairs peuvent être à l’origine d’une électrocution.
16. N’utilisez pas le téléphone pour rapporter une fuite de gaz à proximité de celle-ci. Sous certaines circonstances, une inteincelle
pourrait survenir lorsque l’adaptateur est branché à une prise de courant, ou lorsque le combiné est déposé sur le combiné.
Ceci est un événement commun associé avec la fermeture d’un circuit électrique. L’utilisateur ne devrait pas brancher le
téléphone dans une prise de courant, et ne devrait pas déposer le combiné chargé sur le socle, si le téléphone se trouve dans
un environnement ou la concentration de gaz inflammables, sans ventilation adéquate. Une étincelle dans ces endroits pourrait
provoquer un incendie ou une explosion. Ces environnements pourraient être l’utilisation médicale de l’oxygène sans ventilation
adéquate; le gaz industriel (dissolvants, vapeurs d’essence, etc.); une fuite de gaz naturel, etc.
17. Placez uniquement le combiné de votre appareil près de votre oreille lorsqu’il est en mode de conversation normal.
18. Les adaptateurs sont conçus pour être orientés en position verticale ou en position horizontale sur le plancher. Les fiches ne sont
pas conçues pour maintenir la prise en place si celle-ci est branchée au plafond, sous la table ou les armoires.
19. Pour les PRODUITS À BRANCHER À UNE PRISE DE COURANT, la prise de courant doit être installée près du produit, afin
d’assurer une accessibilité sécuritaire à la prise de courant.
20. N’utilisez que cordon d’alimentation et les piles indiquées dans ce guide d’utilisation. Ne jetez pas les piles au feu. Celles-ci
risqueraient d’exploser. Vérifiez avec les règlements locaux afin de vous assurer de respecter les instructions spéciales de mise
aux rebus de teilles pièces.
21. En position de montage mural, assurez-vous de monter le socle du téléphone sur le mur en alignant les oeillets avec les goujons
de fixation de la plaque murale. Ensuite, faites glisser le socle vers le bas sur les deux goujons de fixation jusqu’à ce qu’il se
verrouille en place. Reportez-vous aux instructions complètes dans la section Installation dans ce guide d’utilisation.
22. MISE EN GARDE : Éloignez les petits objets métalliques tels que les broches de l’écouteur du combiné.
23. MISE EN GARDE : Il pourrait y avoir un risque d’explosion si un mauvais type de pile est utilisé pour le combiné
(A2410,A2420, C4100, C4200, CTM-A241HS, CTM-A241SD, CTM-A242HS, CTM-A242SD, CTM-A2411, CTM-A2411-BATT,
CTM-A2421,CTM-A2421-BATT, CTM-A2510, CTM-A2510-USB, CTM-C4101 and CTM-C4201) . N’utilisez que la pile
rechargeable (BT264392/BT266342) incluse, ou une pile de rechange (BT266342). Veuillez jeter les piles mortes en respectant
les instructions de la section RBRCMD du guide d’utilisation.
