Problem

Possible cause

Solution

The adapter/

appliance becomes 

warm during 

charging.

This is normal.

No action required.

I have switched on 

the appliance but I 

cannot increase or 

decrease the light 

intensity.

The appliance 

has to be reset.

To reset the appliance, switch off the appliance and 

then switch it on again. If you still cannot adjust the light 

intensity, contact the Consumer Care Centre in your country, 

your Philips dealer or a Philips service centre.

 The ‘ready to flash’ 

light does not 

work when I place 

the appliance on 

the skin.

You have not 

properly placed 

the appliance on 

the skin.

Place the appliance at a 90° angle onto the skin in such a way 

that all 4 sides of the integrated safety system touch the skin. 

Then check if the ‘ready to flash’ light lights up continuously 

and press the flash button.

If this does not work, place the appliance on a part of 

your body where it is easy to establish full skin contact, for 

example on your lower arm.Then check if the ‘ready to 

flash’ light works. If the ‘ready to flash’ light still does not start 

flashing when you place the appliance on the skin, contact the 

Consumer Care Centre in your country, your Philips dealer 

or a Philips service centre.

The ‘ready to 

flash’ light does 

not work when 

I place the body 

attachment on 

my skin, but the 

cooling fan works.

The overheat 

protection has 

been activated.

When the overheat protection has been activated, the fan 

still works. Do not switch off the appliance and let it cool 

down for approx. 15 minutes before you continue to use it. 

After 5 minutes the appliance switches off automatically. Then 

let it cool down for 10 more minutes. If the ‘ready to flash’ 

light still does not work when you place the appliance on 

the skin, contact the Consumer Care Centre in your country, 

your Philips dealer or a Philips service centre.
