Safety Instructions
Note: When using your telephone or connected
equipment, the following basic safety precautions
should always be followed to reduce risk of fire,
electrical shock and other personal injury.
Recommendations
• Always keep and handle your products with care
and keep them in a clean and dust-free place.
Proper use and care will prolong the products
life. Use a soft absorbent tissue or cloth to

• Always ensure that the phone, battery and
charger are used and operated in the
environment for which they are designed.
• Operate the phone in temperatures between
0°C to +40°C (32°F to 104°F).
• Do not expose your products to
liquid, moisture, humidity, solvents,
strong sunlight, harsh environments
or extreme temperatures, never
above +60°C (+140°F), unless the
product has been specifically
designed and officially approved for such
environments.
• Exposure to heat may cause
batteries to leak, overheat or
explode, resulting in fire, burns or
other injuries.
• Do not put the product in the micro-
wave oven: This may cause damage to either
the oven or the product.
• Do not attempt to disassemble or
alter any part of the phone, the
charger(s) or the battery-pack.
Disassembly or alteration may result
in electrical shock or irreversible
damage to the equipment. Only a
qualified service personnel or an authorized Mitel
partner should conduct internal inspections,
alterations and repairs.
• Do not expose your product to open flames or lit
tobacco products.
