Note:  
1. Overload is indicated by the ring indicator flashing once every 3 seconds.
2. The Electronic Dimmer will resume normal operation once the overload is  
    removed, by switching off and on.

Soft start operation

When the Electronic Dimmer is switched on, light levels gradually reach the 
desired level over a period of 1 to 3 seconds, greatly extending life expectancy of 
lamps by avoiding initial power surge.

Overload protection

If the Electronic Dimmer is overloaded input to lamp(s) will be reduced (or 
switched off if overload is severe) to protect the device and the installation.

Maintenance

Cleaning

Please clean the device with a dry and soft lint free cloth. 
Do not use water or any abrasive solvent based or aerosol cleaners as this may 
damage, discolor or affect the finish and safety of the appliance.

Features

Power failure recovery

In case of power failure, the dimmer will restore to its previous state upon 
power restoration.

Minimum brightness adjustment 

The User can adjust the minimum brightness level to suit their environment 
and ensure optimum lamp performance. See User Guide for programming 
details.

Troubleshooting

Unable to fit frontplates to module

Please check if you are fitting the correct frontplate to the correct module. The 
frontplate must match the module exactly, e.g. 1 Gang Electronic Dimmer Frontplate 
will only fit a 1 Gang Electronic Dimmer Module. Please refer to the instructions for 
fitting and removing frontplates on page-3.

Connected Lamp does not turn ON or DIM

Firstly check the lamps have not expired.
Check connections and wiring to the device to ensure it has been 
installed correctly.
Check the circuit, by inspecting other devices on the same circuit, to 
ensure there is power input to the device.

Ring indicator flashes once every 3 seconds

This is indication of an overload. The Electronic Dimmer will resume normal 
operation once the overload is removed, by switching off and on.
If you are facing a problem not listed here, please contact the MK technical team. 
(Contact details are listed on the last page)

Notes:

1. Do not use loads of different types on the same circuit.

2. Not suitable for use with any other load type.

3. *Neutral connection is required. It is recommended to connect neutral whenever possible to  

     extend the load handling capability of the dimmer.
