Press the 

POWER

 button and the instrument name appears.  Allow the 

instrument to scroll through its start-up sequence before pressing any other 

button, this will take approximately 3 seconds. 

 

 

When the instrument has completed its start-up sequence the display will 

change to LP (or Lex on GA256) in PAUSED mode using the settings that were 

last selected.  

 
To switch off, press and release the 

POWER

 button once and the display goes 

blank.

 

 

 

Castle instruments operate with an intuitive menu and status system.  The 

menu is selected by using the dedicated buttons on the keypad.  A scrolling 

menu exists within this function, repeated pressing of the buttons will allow you 

to scroll through the menu. 

 

The example below shows the status of the instrument. The displayed 

messages may vary due to different instrument functions and configurations.
