Electromagnetic compatibility (EMC)

Portable and mobile radio frequency communication equipment, such as mobile phones, cordless

telephones and their base stations, walkie-talkies, and wireless home network devices (routers), can

affect the Philips EnergyUp. They must therefore not be used in close proximity to the EnergyUp. If

this cannot be avoided, the EnergyUp must be observed to verify normal operation. If abnormal

performance (e.g. loss of functionality, light inconsistency, flicker) is observed, additional measures

may be necessary, such as re-orientation of the radio frequency communication equipment or the

EnergyUp (see section 'EMC information' in chapter 'Specifications' for more details).

General

The adapter is equipped with an automatic voltage selector and is suitable for mains voltages ranging

from 100 to 240 Vac, 50/60 Hz.

Using the appliance

When to use

Knowing at what time to use the Philips EnergyUp is essential. It may mean the difference between

feeling better in a few days instead of weeks and between experiencing benefits or experiencing

none. Follow these guidelines to understand how light affects us and when to use the Philips

EnergyUp for the best results.

Duration

Most people experience benefits if they use the appliance 20 to 30 minutes each day. It is safe to use

the Philips EnergyUp longer, provided you do so at the correct time of day. You may notice some

energizing effects of light immediately. Other effects become noticeable after several days of regular

use.

Indoor life and energy dips

If you spend a lot of time indoors with little daylight and artificial light, you can experience the

energizing effects of the Philips EnergyUp very quickly after you switch it on.

Many people experience a natural dip in the afternoon. The Philips EnergyUp can help you counteract

this dip.

Winter blues

If you experience lower energy levels, an increased need for sleep, and a lower mood in the dark

season compared to spring and summer, use the energy light for 20-30 minutes a day. Preferably use

it in the morning to help you start the day. You may also use it later during the day, but do not use it in

the last few hours before bedtime. If you do, the light could delay your sleep and make you even less

energetic the next day.

Winter depression

If your seasonal mood swings are more severe and you suffer from depression, consult a therapist and

only use light therapy under supervision. Your therapist may prescribe 30 minutes of treatment per

day at level 1 or 2 over several weeks.
