M500 Multi-cell SIP DECT Base Station Quick Installation Guide illustration scale 100% Taihoon Kim | 09. Apr. 2021 | Revision 3.2AW / M500 Cordless base 2 Important Safety Information This symbol is to alert you to important operating or servicing instructions that may appear on the product or in this user’s manual. Always follow basic safety precautions when using this product to reduce the risk of injury, fire, or electric shock. Important Safety Instructions When using your telephone equipment, basic safety precautions should always be followed to reduce the risk of fire, electric shock and injury, including the following: 1. This product should be installed by a qualified 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 base station 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 supplied at 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 base station or handset because they may touch dangerous voltage points or create a short circuit. Never spill liquid of any kind on the product. 3 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 base station or handset other than specified 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: A. When the power supply cord or plug is damaged or frayed. B. If liquid has been spilled onto the product. C. If the product has been exposed to rain or water. D. 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. E. If the product has been dropped and the telephone base and/or handset has been damaged. F. 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 flammable or flame-supporting gases, unless there is adequate ventilation. A spark in such an environment could create a fire 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 floor 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. 4 19. Use only the power cord indicated in this manual. 20. For pluggable equipment, the socket-outlet shall be installed near the equipment and shall be easily accessible. 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 installation instructions in the User Manual. 22. CAUTION: Keep small metallic objects such as pins and staples away from the handset receiver. 23. WARNING: The product included (ITE) in this manual is to be connected only to PoE networks without routing to the outside plant.
