Service Information
The Quartet contains no user-serviceable components; refer to qualified service personnel for repair or 
upgrade. Your warranty will be voided if you tamper with the internal components. If you have any 
questions with regard to the above, please contact Apogee. 
In the event your Quartet needs to be upgraded or repaired, it is necessary to contact Apogee prior to 
shipping, and a Return Materials Authorization (RMA) number will be assigned. This number will serve 
as a reference for you and helps facilitate and expedite the return process. Apogee requires that 
shipments be pre-paid and insured — unless otherwise authorized in advance.
IMPORTANT: ANY SHIPMENT THAT IS NOT PRE-PAID OR IS SENT WITHOUT AN RMA NUMBER WILL NOT 
BE ACCEPTED.
