PK1 Wireless brightness dimmer is used with single or many L4-M receivers, connected to DLC-D series LED drivers to power up ELS-L series LED lights. To launch LED lights brightness control:

1. connect L4-M receiver's output with DLC-D driver's 0-10V input
2. connect L4-M to power source ~230V AC or 12-24V DC
3. remove protective film from PK1 battery
   
4. match PK1 dimmer and L4-M

Then all four steps are complete, simply rotate knob clockwise to increase brightness, and anticlockwise to decrease. Push knob to turn LED light ON or OFF.

Each PK1 wireless dimmer can match with one or many receivers. To simultaneously control all available DLC-D drivers just match PK1 with every L4-M receiver.
