Important Information
Proprietary Telephones
When using the KX-T7700 series, keep the following conditions in mind.
• If there is any problem, unplug the extension line and connect a known working phone. If
the known working phone operates properly, have the defective phone repaired by a
specified Panasonic Factory Service Centre. If the known working phone does not
operate properly, check the PABX System and the internal extension wiring.
• Keep the unit away from heating appliances and electrical noise generating devices such
as fluorescent lamps and motors.
• The unit should be kept free of dust, moisture and vibration, and should not be exposed to
direct sunlight.
• Do not use benzine, thinner, or any abrasive powder to clean the cabinet. Wipe it with a
soft cloth.
• Do not disassemble this unit. Dangerous electrical shock could result. The unit must only
be disassembled and repaired by qualified service technicians.
• When a failure occurs which exposes any internal parts, disconnect the telephone line
cord immediately and return the unit to a service centre.
• This unit is designed to be installed under controlled conditions of ambient temperature
and a relative humidity not greater than 60%.
• Avoid installing the unit in damp or humid environments, such as bathrooms or swimming
pools.
• Do not push the PAUSE button more than twice following the initial access digit (or digits).
Failure to comply with this requirement may result in unsatisfactory operation.
• 999 or 112 can be dialled on the product after accessing the CO line for the purpose of
making outgoing calls to the BT emergency (999) and (112) services.
