Introduction

Read this user manual carefully before using this Philips appliance.

Intended use

This Philips appliance EnergyUp Intense Blue is intended to make people feel more energetic, to adjust circadian rhythms and to provide relief from the winter blues.

Light - a natural energiser

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 energised throughout the day – just like healthy nutrition and regular exercise. This Philips appliance EnergyUp Intense Blue mimics the natural energising 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 this Philips appliance EnergyUp Intense Blue at the right time of day can help you establish and reinforce regular sleep patterns.

Light via eyes

Research shows that a special photoreceptor in our eyes is responsible for regulating our energy, mood and sleep/wake cycles. This receptor responds mostly to the blue light of the summer sky. We do not get much of this light in autumn and winter. Most indoor light does not provide enough of this essential colour. This appliance helps you to be at your best by delivering the wavelength, colour and intensity of light to which our body responds most efficiently.

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. Blue light therapy is a successful method to fight these winter blues symptoms. It provides your body with summer vitality throughout the dark winter months.

• This is not a general illumination product.

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.

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.

Charging

To operate the appliance corded, connect it to a wall socket. For more flexibility, charge the rechargeable battery. Charging takes approximately 3 to 4 hours

Note: You can use the appliance while it is charging. The charging time is longer when you use the appliance while it is charging.

1 Fold out the stand and place the appliance on a table (Fig. 2).
2 Insert the small plug into socket on the appliance (Fig. 3).
3 Put the adapter in the wall socket.

The charge indicator pulsates green during charging. When the battery is fully charged, the charge indicator turns solid green. It continues to light up solid green for 1 hour and then goes off (Fig. 4).

Note: When the battery is fully charged, it contains enough energy for about 1 hour of use at full intensity.

Using the EnergyUp

When to use

Knowing at what time to use the appliance 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 appliance 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 appliance longer, provided you do so at the correct time of day. You may notice some energising 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 energising effects of the appliance very quickly after you switch it on.

Many people experience a natural dip in the afternoon. This Philips appliance 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.

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 appliance in the evening.
• 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 appliance within the first 1-2 hours after you get out of bed. Avoid bright light or blue-rich light in the last 4 hours before bedtime. Daily use of the appliance 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 appliance immediately after you wake up. This could give your body a signal that is opposite to the one intended.

Jet lag

Rapidly travelling 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.

Travelling 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 appliance. 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 appliance 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.

ENGLISH14

Travelling west

Since most people's body clocks adjust more easily to later time zones, you only have to use the appliance 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 appliance 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 appliance in the morning for a few days.

Light intensity

Use the appliance in addition to the normal room lighting. This Philips appliance 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 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. 5).

• 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.
• Use the appliance in a well-lit room to minimise eyestrain.

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

2 Press the on/off button briefly to switch on the appliance (Fig. 6). The first time you switch on the appliance, the light comes on at the default middle intensity setting (setting 3) of 5 intensity settings

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

3 You can choose five intensity settings.

To choose a lower setting, touch the - button briefly (Fig. 7).
To choose a higher setting, touch the + button briefly (Fig. 8).

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

4 The timer indicator shows the time that elapsed since you switched on the appliance.

The timer indicator has 6 segments. Each segment represents 10 minutes. All segments together represent one hour.
When you switch on the appliance, the first segment of the time indicator starts flashing (Fig. 9).

5 If you use the appliance on its rechargeable battery, the charge indicator lights up solid orange after about 1 hour to let you know that the rechargeable battery is low. Connect the appliance to the mains to charge the rechargeable battery (Fig. 10).

Note: You can use the appliance while it is charging.

6 If the battery runs low and the appliance is not connected to the mains, the light will switch off after some time.
7 After the light has switched off, the charge indicator starts flashing orange to indicate that the battery is empty and the appliance will switch off (Fig. 11).
