9.4 The „Lock- function“
To lock your VL 750 / VL 760 (with or without password) please do the following
instructions:
Set all required parameters (also the volume controls) and press, like shown in the
graphics, the OK-button for 2 seconds and your system is locked (now your unit is ready
for a rental, for example). After pressing the OK-button you have to disconnect the mains
plug to switch off the unit. When you connect the mains plug again the “lock-function” is
re-activated. That means you can not change any settings (depending on settings before)
while the “lock-function” is activated. To deactivate the “lock-function” you have to press
the OK button again for 2 seconds and, if entered before, enter your password by using
the arrow keys and confirm with OK.
Attention!
If you have changed the position of the volume control during the VL 750 /
VL 760 was locked you will be informed on the LCD display. Now you have two
possibilities to unlock the unit: after entering your password (if entered before) you can
press the OK button for two times and the VL 750 / VL 760 is playing in the current
adjustment of the volume control or you press the OK button only once after entering your
password (if entered before) and turn the volume control to the previous position.
