Trademarks
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 microphone (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 telephone.
• 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.

Function keys
Depending on how they are programmed by service personnel, you can use the keys as:
• Function keys
• Repdial keys
• Trunk key
The function keys (except for the "Shift" key) can be programmed on two levels. The "Shift"
key must be configured for this and extended key functionality must be active (consult your
service personnel). 
Only external phone numbers and internal phone numbers without LED display can be
saved on the second level.
Your service personnel can customise the default assignment – consultation, release, last
number redial – in line with your needs and requirements once the order has been placed.
The status of a function is shown by the LED display for the corresponding function key.

Answering calls
Your OpenStage rings with the tone signal set when an incoming call is received.
• When you receive an internal call, your telephone rings once every four seconds (single-tone sequence).
• When you receive an external call, your telephone rings twice in rapid succession every four seconds (dual-tone sequence).
• When you receive a call from the entrance telephone, your telephone rings
three times in rapid succession every four seconds (triple-tone sequence).
• If a call is waiting, you hear a short tone (beep) every six seconds.
Your service personnel can adjust the ring cadence for external and internal calls for you. In other words, different ring cadences can be set for different internal callers.
