DTS821 Cleaning
You may clean your DTS821 Digital Telephone Set if it is necessary only. Disconnect
the line cord from the body of your set before cleaning. Clean only the surface of your
DTS821 with a slightly wet dust-cloth . Never use any chemical cleaners (liquid or
spray). Leave it to be dried and then connect the line cord again.
DTS821 Periodic Maintenance
Your DTS821 Digital Telephone Set does not contain any parts for periodic
maintenance. Consequently, periodic maintenance is not a condition at all. However,
you may prefer (or need) some maintenance of your DTS821 for some reason. Please
contact your local Telesis Dealer for his assistance then. In any case, never do this by
yourself. Do not open any covers of your digital telephone set. Do not untighten any
screws on your DTS821.
