Care and maintenance
The ISDN system telephone has been manufactured for normal, everyday use. When required, clean the
ISDN system telephone with a slightly moistened cloth, or with an anti-static cloth. Never use a solvent to
clean the phone! Never use a dry cloth; electrostatic charges could damage the electronics in the system. It is
essential that no liquids penetrate into the inside of the ISDN system telephone, as this could destroy the
phone.
Installing the telephone
Before installing the telephone you must mount the rear feet for the telephone at the positions (6) shown in
figure 4. Depending on the height of these two feet you can adjust the display angle of your phone to your
personal angle of vision. Ensure that the two feet have the same height.
To adjust the height, pull the feet off of the bottom of the telephone, rotate them around 60° and place them
back in the enclosure. By turning the feet by around 60° (around the longitudinal axis) each time you can set
three different heights for the phone.
Please note that the plastic feet of your telephone may leave marks on sensitive surfaces, such as furniture.
The manufacturer of the telephone is not liable for any such damage. Therefore, use appropriate non-skid-
ding pads under the phone.
