The UP/DOWN keys change the value for the start address. The ULD-340 uses 
the changed value immediately and permanently saves it after 10 seconds or if 
the Enter or Menu key is pressed. 

 

After power on, the ULD-340 remains in the Address Menu in its simple interface 
mode. To go to any other menu requires the user to hold the MENU key for about 
5 seconds.

entered.  Press the ENTER key saves the change, and advance to the next 
channel. 

 

The LD-340 returns to the Address Menu automatically after 4 seconds if no 
keys are pressed in the Mode Menu.
