Potentially explosive environments
Switch off your device when in any area with a potentially explosive atmosphere and obey all signs and instructions.
Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Switch off the device at
refuelling points such as near gas pumps at service stations. Observe restrictions on the use of radio equipment in fuel
depots, storage, and distribution areas; chemical plants; or where blasting operations are in progress. Areas with a
potentially explosive atmosphere are often but not always clearly marked. They include below deck on boats, chemical
transfer or storage facilities, vehicles using liquefied petroleum gas, and areas where the air contains chemicals or
particles such as grain dust or metal powders.
Sensitive Electronic Equipment
The current state of research concludes that operational DECT phones normally do not adversely affect electronic
equipment. Nevertheless, you should take some precautions if you want to operate DECT phones in the immediate
vicinity of such equipment like sensitive laboratory equipment. Always keep a minimum distance of 10 cm (3.94“) to the
equipment even when the phone is in standby.
Electrical Surges
We recommend the installment of an AC surge arrester in the AC outlet to which this device is connected to avoid damage
to the equipmen t caused by local strikes of lightening or other electrical surges.
Important Battery Information
The handset uses a rechargeable battery pack,
Model name
Supplier
Ni-MHAAA550mAh 2.4V (NI-MHAAA550*2)
Yiyang Corun Battery Co., Ltd.
Only use the batteries that came with the handset or suitable replacement batteries recommended by Snom. Do not use
any other type of battery since this may lead to leakage, fire, explosion, or other dangerous situations. Never disassemble,
alter, or short-circuit batteries or use them for purposes other than the intended one. Charge battery only within the
handset placed in the charger that came with the product.
Charging and Discharging, Storage
• CAUTION
: Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the
instructions.
• The full performance of a new battery is achieved only after two or three complete charge and discharge cycles.
• The battery can be charged and discharged hundreds of times, but it will eventually wear out. Use only Snom
Technology GmbH approved batteries.
• If left unused, a fully charged battery will lose its charge over time. If the batteries are completely discharged, it may
take a few minutes before the charging indicator appears on the display.
• Use the batteries only for their intended purpose. Do not short-circuit the batteries. Short-circuiting the terminals may
damage the batteries or the connecting object. Do not use a damaged charger or battery. Using a damaged battery
may cause it to explode.
• Do not place or store the batteries, inside or outside the handset, in the immediate vicinity of open fire or other heat
sources.
• Leaving the batteries in hot or cold places will reduce their capacity and lifetime. Charge batteries within an ambient
temperature range of 5° C to 40° C (41° F to 104° F). A device with hot or cold batteries may not work temporarily, even
when the batteries are fully charged.
• Avoid overcharging. Repeated overcharging can lead to deterioration in battery performance. Never attempt charging
the batteries with reversed polarity as this may cause the gas pressure inside the batteries to rise and lead to leakages.
• Remove batteries if storing phone for more than 1 month.
• Store batteries in a cool, dry place without corrosive gases. Storage up to 6 months: Charge battery to 30% to 70% of
its capacity and store at -10° C and +40° C (14° F to 104° F). Relative humidity approx. 50%.
Battery Disposal
Defective or exhausted batteries should never be disposed of as municipal waste. Return old batteries to the battery
supplier, a licensed battery dealer or a designated collection facility. Do not incinerate batteries.
