1.9 Temperature and ambient conditions
The telephone is designed for use in protected rooms with a temperature
range from 10 °C to 30 °C. The base station should not be used in rooms
exposed to moisture, such as bathrooms or laundries. Do not locate the
device in the vicinity of sources of heat such as radiators, and never
expose it to direct sunlight.
Do not use the handset in potentially explosive areas.
Prevent excessive exposure to smoke, dust, vibration, chemicals,
moisture, heat and direct sunlight.
1.10 Cleaning and upkeep
Clean the housing surfaces with a soft, dry, fluff−free cloth. Never use
cleaning agents or aggressive solvents. Apart from occasionally cleaning
the housing, no other upkeep is necessary. The rubber footpads on the
base station are not resistant to all cleaning agents. Therefore, the
manufacturer is not liable for any damage caused to furniture etc.
