Philips TRESemme HP4668/27 User Manual Download Page 2

Keep the straightening plates clean and free of dust and dirt. Dust and 

dirt may cause damage to the straightening plates.

If you use styling products, always clean the straightening plates after 

they have cooled down to avoid damage to the straightening plates.

The plates have a ceramic coating. This coating slowly wears away over 

time. This does not affect the performance of the appliance.

Do not use the appliance for any other purpose than described in this 

user manual.

If you use the appliance on colour-treated hair, the straightening plates 

may stain.

The maximum temperature occurs just after heating up. The actual 

temperature during use may be lower.

Electromagnetic fields (EMF)

This Philips appliance complies with all standards regarding electromagnetic 

fields (EMF). If handled properly and according to the instructions in this 

user manual, the appliance is safe to use based on scientific evidence 

available today.

Using the appliance

Straighteners are powerful styling tools and must always be used with care. 

As with all straighteners that reach salon-high temperatures, do not use the 

appliance frequently to avoid damage to the hair. If you use the straightener 

incorrectly, you could overheat your hair or even burn it. Always make sure 

you select a temperature that is suitable for your hair type.

Straightening

The display shows the selected temperature setting and the remaining 

time of the straightening session.

The bars on the display show the remaining usage time of the 

straightener. The total usage time is 60 minutes. Every ten minutes one 

of the six bars disappears. After 60 minutes the appliance switches off.

 1 

 Put the plug into the wall socket. 

 2 

 Press the on/off button. 

The default temperature setting of 120 appears on the display. As 

soon as the appliance has heated up to this setting, the word ‘READY’ 

appears on the display (Fig. 2).

Never leave the appliance unattended when it is plugged in. Always put 

the appliance on a heat-resistant surface when it is heating up and when 

it is hot.

Tip: The straightener heats up more quickly if you lock the plates with 

the closing lock.

 3 

 Select a temperature setting that is suitable for your hair. 

Always select a low temperature setting when you use the straightener 

for the first time. 

For coarse, curly or hard-to-straighten hair, select a medium to high 

setting (180 and up).

For fine, medium-textured or softly waved hair, select a medium to low 

setting (170 and down).

Take extra care with pale, blonde, bleached or colour-treated hair, since it 

is susceptible to damage at high temperatures.

 4 

 To set the temperature setting, press the + button to increase 

the temperature setting or press the - button to decrease the 

temperature setting. 

The display shows the selected temperature setting.

When the appliance has heated up to the selected setting, the word 

‘READY’ appears on the display.

Danger 

Keep the appliance away from water. Do not use it near or over water 

contained in baths, washbasins, sinks etc. When you use the appliance in 

a bathroom, unplug it after use. The proximity of water presents a risk, 

even when the appliance is switched off.

Warning

Check if the voltage indicated on the appliance corresponds to the local 

mains voltage before you connect the appliance.

Check the condition of the mains cord regularly. Do not use the 

appliance if the plug, the mains cord or the appliance itself is damaged.

If the mains cord is damaged, you must have it replaced by Philips, a 

service centre authorised by Philips or similarly qualified persons in 

order to avoid a hazard.

This appliance is not intended for use by persons (including children) 

with reduced physical, sensory or mental capabilities, or lack of

Never leave the appliance unattended when it is plugged in.

Always return the appliance to a service centre authorised by Philips 

for examination or repair. Repair by unqualified people could cause an 

extremely hazardous situation for the user.

Caution

For additional protection, we advise you to install a residual current 

device (RCD) in the electrical circuit that supplies the bathroom. This 

RCD must have a rated residual operating current not higher than 

30mA. Ask your installer for advice.

The straightening plates and the plastic parts near the plates reach a 

high temperature quickly. Prevent the hot surfaces of the appliance from 

coming into contact with your skin.

Do not use the appliance on artificial hair.

Only use the appliance on dry or damp hair.

Do not leave the plates in your hair for more than a few seconds at a 

time as this may cause damage to your hair.

For safety reasons, the straightener automatically switches off after 

having been on for 1 hour.

Always switch off the appliance before you put it down, even if it is only 

for a moment. 

Do not wind the mains cord round the appliance.

Wait until the appliance has cooled down before you store it.
