Denon AVR-750 User Manual

LAST FUNCTION MEMORY
* This unt is equipped with a last function memory which stores the input and output setting conditions as they were immediately before the
power is switched off.
This function eliminates the need to perform complicated resettings when the power Is switched on.
* This unit is also equipped with 2 back-up memory. This function provides approximately one week of memory storage with the power cord
disconnected.
TROUBLESHOOTING
if a problem should arise, first check the following:
1. Are the connections correct?
2. Have you followed all operational instructions correctly?
3. Are the speakers, turntable, and other components operating properly?
if the receiver is not operating property, chack the items listed In the table below. Should the problem persist, there may be a malfunction.
Disconnect the power immediately and contact your store of purchase.
