Location Of The Telephone; Software Update - Siemens HiPath 4000 Operation Manual

Location of the telephone

• The telephone should be operated in a controlled environment with an
ambient temperature between 5°C and 40°C.
• To ensure good speakerphone quality, the area in front of the micro-
phone (front right) should be kept clear. The optimum speakerphone
distance is 50 cm.
• Do not install the telephone in a room where large quantities of dust
accumulate; this can considerably reduce the service life of the tele-
phone.
• Do not expose the telephone to direct sunlight or any other source of
heat, as this is liable to damage the electronic components and the
plastic casing.
• Do not operate the telephone in damp environments such as
bathrooms.

Software update

During a software update, the phone must not be disconnected
from the power supply unit, the LAN line or the phone line.
An update action is indicated by messages on the display and/or by
flashing LEDs.
