NOTE 1: After switching from manual mode (LED switch position ON or OFF) to TTL mode
(LED switch position TTL), TTL control of the lamp’s on/off state will resume with the next
change of logic state at TTL IN.
NOTE 2: While using the LED switch to switch from ON to TTL, the lamp turns off while
transitioning through the OFF position (the OFF position is located in between ON and
TTL).
NOTE 3: Switch 4 must be OFF for proper operation of the Lambda HPX (liquid-cooled
lamp).
