Yamaha CLP-811 Owner's Manual - Page 11

Memory Backup The Clavinova includes a memory-backup feature than can retain settings while power is off and restore them when you resume play. Although all backup is set to OFF at time of shipping, you can use the FUNCTION mode's Backup setting (F15 on the CLP-811, F14 on the CLP-611) to selectivety set backup on or off for different groups of settings. If backup for a group is set OFF, all settings within that group return to their factory defaults each time power comes on. (A listing of factory defaults appears on page 47.) Note that the Clavinova unconditionally backs up and restores the Backup settings themselves, as well as any keyboard input that you have recorded. Memory backup remains effective for about a week, after which all settings will return to their factory defaults. If you wish to retain your settings for a long period of time, please be sure to switch the Clavinova on for at least a few minutes each week. CLP-811/611 function groups CLP-811/611 functions can be broadly divided into three groups, as follows. Voice and performance functions (p.13-p.19) Recording and playback functions (p.20-p.23) FUNCTION-mode settings (p.24-p.37) FUNCTION mode... You can use FUNCTION mode to set a wide variety of system and utility parameters. All parameters are originally set to standard default values (factory defaults), but you are free to change them to suit your particular needs. Memory... The Clavinova stores the various settings you have made within its internal memory. Backup... Use the memory backup feature to retain memory settings while power is off, so that they will be restored when you switch the power back on. CLP-811/611 Basic Controls and Functions 7
