5.4 Switching off
Please use one of the following recommended methods for shutting down the LX90xx
system:
Method 1
Press the button with the OFF label which is displayed in navigational modes. See Chapter
6.5 for more details. A message to confirm shutdown will be shown.
Method 2
Press the button with the OFF symbol for approximately 4 seconds. The OFF message will
be displayed and the instrument will shut down. When the message appears you must
release the power button.
Method 3
When the button with the OFF symbol is pressed for more than 8 seconds the system will
perform an unconditional shutdown. This method is recommended only in case that the
program hangs and it is not possible to shutdown with methods 1 or 2.
If you are using method 2 to switch off the system it is necessary to release the
button when you see the shutting down message. If you continue to press the off
button the main display unit may shut down by method 3.
