Read this user manual carefully before using this Philips appliance.

Intended use

This Philips appliance EnergyUp Natural White is intended to make people feel more energetic, to adjust circadian rhythms and to provide relief from the winter blues. Medical intended use of this appliance is to treat winter depression or SAD (seasonal affective disorder). Treatment of SAD must always take place under medical supervision.

Light - a natural energizer

Today's busy modern lifestyles demand peak performance all day long. Even the fittest person suffers energy dips, particularly when deprived of natural daylight, such as in an office in winter. Daylight is essential to well-being, keeping fit and feeling energized throughout the day – just like healthy nutrition and regular exercise. Philips EnergyUp Natural White mimics the natural energizing power of daylight on a bright sunny day. It stimulates special receptors in the eye to trigger the body’s natural response to sunlight. This helps you to fight energy dips, to feel more energetic, active and alert, and to improve your mood.

Circadian rhythms and sleep patterns

The human body uses light cues, such as those provided by the sun, to time certain internal functions. Properly timed rhythms regulate energy, mood, sleep, appetite and digestion. These daily internal cycles, called circadian rhythms, sometimes fall out of sync with nature, which can have impact on our well-being. Nature’s cues no longer govern our modern lifestyle. Our day no longer starts at sunrise and ends at sunset, working days are getting longer, and many people work in shifts. Moreover, our activities often extend well into the night. Many people tend to get too little sleep during the week, which diminishes their energy levels during the day. Using Philips EnergyUp Natural White at the right time of day can help you establish and reinforce regular sleep patterns.

Light via eyes

Research shows that bright light via the eyes influences the regulation of our energy level, mood and sleep/wake cycle. Indoor spaces generally do not provide enough light intensity. This appliance helps you to be at your best by delivering high quality intense light whenever and wherever you need it.

Winter blues

Lack of light during the darker winter months causes many people to experience a noticeable drop in energy level and low spirits as autumn sets in. These symptoms, known as 'winter blues', may cause you to feel low, listless and fatigued for weeks or even months. This affects both personal performance and mood. Bright light therapy is a successful method to fight these winter blues symptoms. It provides your body with summer vitality throughout the dark winter months.

English

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.

Sleep patterns

Morning persons tend to wake up early in the morning and usually find it difficult to stay awake in the evening. If you want to get more out of your evening, avoid bright light directly after waking up and use the Philips EnergyUp in the evening.

English

Evening persons find it difficult to get up in the morning and are full of energy in the evening. If this applies to you, you need morning light. Use the Philips EnergyUp within the first 1-2 hours after you get out of bed. Avoid bright light in the last 4 hours before bedtime. Daily use of the Philips EnergyUp in the morning may help you establish a regular sleep pattern that allows you to function better in the morning.

Note: If your desired wake-up time is less than six hours after your normal bedtime, do not use the Philips EnergyUp immediately after you wake up. This could give your body a signal that is opposite to the one intended.

Jet lag

Rapidly traveling across several time zones puts your internal body clock out of sync with the new external time. This not only causes sleeping problems, but also influences your mood and energy level. If you stay for more than a few days in the other time zone, you may want to shift your body clock to the new time zone. This will help you sleep better and be more alert and energetic when you need to. One of the best strategies to deal with jet lag is to start shifting your body clock and sleep times several days before you leave.

Traveling east

When you travel east, you have to advance your sleep time by a number of hours that equals the time zones you cross. You can shift your body clock forwards in steps of one hour a day. The number of time zones you cross determines how many days before departure you have to start using the Philips EnergyUp. Use the appliance for 30 minutes after you wake up. Avoid bright light in the evening and go to bed early. When you arrive at your destination, avoid bright light during your normal sleep period. Expose yourself to bright light at the end of this period to advance your body clock further to the local time.

Before your return flight, use the Philips EnergyUp late in the evening for a couple of days. On the last night of the trip, try to stay up and use the appliance as late as possible after midnight. On the day of the flight, avoid any bright light in the morning.

English

Traveling west

Since most people’s body clocks adjust more easily to later time zones, you only have to use the Philips EnergyUp for one day before you travel across four time zones. Add an additional preparation day for each three additional time zones. You do not have to use the Philips EnergyUp for more than three days, even on longer westbound trips. Use the appliance for 30–40 minutes late in the evening. Start two or three days before you leave. Use the appliance two hours later the following nights.

When you arrive at your destination, try to stay awake until bedtime and avoid bright evening light (wear sunglasses) for the first few days. Before you travel home, avoid any bright afternoon and evening light. Use the Philips EnergyUp in the morning for a few days.

Light intensity

Use the Philips EnergyUp in addition to the normal room lighting. The Philips EnergyUp is more comfortable to use in a well-lit room. Adjust the brightness to a comfortable level. Allow a few minutes for your eyes to get used to the bright light. If the highest setting is too bright for you, start using the appliance at a lower setting. Increase the light intensity if you feel no effect after a week.

How to use the appliance

1 Insert the small plug in the socket on the back of the appliance (Fig. 2). 2 Fold out the stand. To ensure the light reaches your eyes, this appliance has a stand that can be

set to a variable angle.

If you are sitting higher or standing and the top edge of the appliance is below eye level, place the appliance in a tilted position so that its light points further upwards and reaches your eyes (Fig. 3).

If you are sitting at a table or desk and the top edge of the appliance is above eye level, you can place the appliance in a more upright position (Fig. 4).

You can also use the stand to hang the appliance on the wall (Fig. 5).

Note: To hang the appliance on a wall, drill two holes 100-120mm apart and insert two hooks with a diameter of 4mm (Fig. 6).

3 Insert the adapter in a wall socket (Fig. 7). 4 Place the appliance at arm’s length (at approximately 50-75cm from your eyes) within your field of

vision. The light must bathe your face (Fig. 8).

You can read, eat, work at the computer, watch TV or exercise while you use the appliance.

For the best results, place the appliance at the same level as your midriff (stomach area), e.g. place it on the table at which you are sitting.

Make sure that the surroundings of the appliance are well-lit for more visual comfort.

Note: Do not stare into the light of the appliance. It is sufficient that the bright light reaches your eyes indirectly.

5 Press the on/off button briefly to switch on the appliance (Fig. 9).

The first time you switch on the appliance, the light comes on at the default intensity setting (setting 4) of 6 intensity settings.

The next time you switch on the appliance, the light comes on at the last used intensity setting.

6 You can choose six intensity settings.

To choose a lower setting, touch the - button briefly (Fig. 10).

To choose a higher setting, touch the + button briefly (Fig. 11).

Note: For the best results, use the highest light setting that is comfortable to your eyes.

English

Time and intensity level indicator bar

The appliance has an indicator bar with 6 segments that can show either the selected intensity level (1 to 6) or the time elapsed (0 to 60 minutes) since you switched on the appliance.

When you press the on/off button to switch on the appliance, the indicator briefly shows the set light intensity level, followed by a transition to the time elapsed since the appliance was switched on.

Each time you press the + or - button to change the light intensity, the indicator bar briefly shows the newly selected light intensity, followed by a transition to the time elapsed mode.

Intensity level indicator mode The indicator bar has 6 segments. Each segment represents a light intensity level. The segment on

the left-hand side shows the lowest intensity level (1), while the one on the right-hand side shows the highest level (6).

The segment that shows the selected light intensity level lights up solid, while the others are at a lower light level. For example: when you switch to light intensity level 4, segment 4 will light up solid while the others are at a lower level (Fig. 12).

Time elapsed mode The indicator bar indicates the time elapsed since you switched on the appliance. It has 6

segments. Each segment represents 10 minutes. All segments together represent one hour.

After you switch on the light, the first segment on the left-hand side of the indicator bar flashes slowly (Fig. 13).

After 10 minutes, the first segment lights up solid and the second segment starts flashing slowly (Fig. 14).

This process continues, until all segments of the time indicator bar light up solid after 1 hour (Fig.

15).

Note: If you want to switch off the appliance, press the on/off button briefly.

Cleaning and storage

Do not immerse the appliance in water or any other liquid and do not rinse it under the tap.

Never use scouring pads, abrasive cleaning agents or aggressive liquids such as petrol or acetone to clean the appliance.

1 Clean the appliance with a dry or moist cloth. Do not use a wet cloth (Fig. 16). 2 Store the appliance in a safe and dry place.
