Select the respective memory slot “P1, P2 or P3” on the rear slider. The respective output voltage is indi-
cated on the display (2).
Now you can connect and switch on the consumer.
For deactivating the fixed voltage function, slide the “MODE” (13) slider back to the “Normal” position. The
LED display “REAR CONTROL” (6) goes out. The device switches back to normal power unit operation
(always remove DC consumers before!)

Assigning memory slots with “Set”
All three memory slots can be assigned user-specific values for output voltage and current limitation. 



For this purpose, proceed as follows:
Activate the “Set” function through the “MODE” (13) slider on the 
rear. Put the switch in the “Set” position. The front LED display
“REAR CONTROL” (6) lights up. 

Select the respective memory slot “P1, P2 or P3” on the rear “RECALL” (15) slider. The respective
values for current and voltage are indicated on the display (2/3).
The front rotary controls (7 and 8) can be used to set the desired output voltage and current limitation.
If required, repeat these steps with the other memory slots. 
When all parameters are set, slide the “MODE” (13) slider back to the “Preset” position for fixed voltage
operation or to the “Normal” position for standard operation. 

Reset to memory slots to default settings
Switch off the power unit.
Press the two rotary controls on the front at the same time and keep them pressed.
Switch on the power unit. When the displays light up, let go of both rotary controls. The default settings
for the parameters are active again.
