Care
The TEP 3800 does not require any special care. You may remove
fingerprints from the chrome faceplate using a glass cleaner and
polish with a soft, flat cloth. Rub off the side flanges, also using a
glass cleaner and soft cloth.
Do not use benzene, alcohol or other lightly volatile substances
for cleaning ,and be careful not to allow cleaning liquids to
enter the unit!
HIGH VOLTAGE. DO NOT OPEN THE CABINET.
DANGER TO LIFE!
Replacing tubes
Due to the notably gentle and automatically controlled mode of
operation in the TEP 3800, you may under normal conditions
anticipate a lifespan of the tubes of more than 20 years. At the same
time there are replacement tubes available in case of a defect or
malfunctioning. Like the tubes in the appliance, those tubes are also
measured with special testing devices and selected in pairs. Please
read the service and warranty conditions for more information.
You may not replace the tubes in the TEM 3800 by similar or
supposedly pin-compatible types, as the appliance might be
destroyed thereby!
Unauthorized opening of the cabinet as well
as repairs and modifications by unauthorized
personnel may result in the loss of all warranty
claims.
