If you have disabled the "Restore Factory Defaults" function for the "SELECT/SET" button
in the configuration, this does not apply during the startup phase, see section "Restoring
the factory settings (Page 66)".
If the function has been disabled in the configuration, it is only disabled on completion of
the startup phase.
Procedure
To reset the device to the factory defaults during operation, follow the steps below:
1.
Switch to display mode A.
Display mode A is active if the LEDS "DM1" and "DM2" are unlit.
If the "DM1" and "DM2" LEDs are lit or flashing, you will need to press the "SET/SELECT"
repeatedly until the "DM1" and "DM2" LEDs go off.
If you do not press the "SELECT/SET" button for longer than 1 minute, the device
automatically changes to display mode A.
2.
Hold down the "SELECT/SET" button for 12 seconds.
After 9 seconds,the "DM1" and "DM2" LEDs start to flash for 3 seconds. At the same
time, the port LEDs go on one after the other.
After you have held down the button for 12 seconds, the factory defaults are restored.
If you release the button before the 12 seconds have elapsed, the reset is canceled.
Enabling and disabling the button
In the configuration, you can enable or disable the button function.
