Preparation

Charging the shaver

Turn the shaver off.
Wipe off any water droplets on the appliance socket.

Insert the appliance plug into the shaver.
Plug the adaptor into a household outlet.
- Check that the charge status lamp ( ) is glowing.
- Charging is completed after approx. 1 hour
Disconnect the adaptor after charging is completed and the charge status lamp ( ) turns off

Note: You cannot operate the shaver while charging.

Quick charge
Even though the battery runs out, you can shave once after 3-minute charge.
(This will differ depending on usage.)

After charging is completed, turning the power switch ON with the shaver plugged in will cause the charge status lamp ( ) to light up and then turn off after 5 seconds.
This shows that the shaver is fully charged.
When charging the shaver for the first time or when it has not been in use for more than 6 months, thecharging time may change or the charge status lamp ( ) may not glow for a few minutes. It will eventually glow if kept connected ambient temperature for charging is 10 °C – 35 °C. It may take longer to charge or thebattery may fail to charge properly in extremely high or low temperatures. The charge status lamp ( ) will blink twice every second when there is a problem with charging. Charge the shaver within the recommended ambient temperature range.
The shaver can be used for approximately 2 weeks with a full charge. (Based on one 3-minute dry-shave usages per day in an ambient temperature range of 20 °C – 30 °C.)
The number of usable days varies depending on the following conditions.
- Beard thickness
- Pressure applied to the skin
- Usage of wet shaving
- Usage in shaving foam mode
If there is noise from the radio or other sources while using or charging the appliance, move to a different location to use the appliance.

**How to use

**

Usable facial cleansers, etc.

Do not use anything other than above listed shaving agent/facial cleanser/body soap etc. as these may cause the blades to clog, or be unable to make foam.

Making foam in shaving foam mode It is easier to make foam this way than by hand.

Take an appropriate amount of facial cleanser etc. in the palm of your hand.
Add an appropriate amount of water or hot water.
Check that the cleaning shutter is closed and hold the power switch for 2 seconds or more to switch to shaving foam mode The switch lock lamp ( ) and charge status lamp ( ) blink alternately.
- The shaving foam mode ends after 15 seconds. The shaver can then be used to shave.
- To stop using the shaving foam mode and start shaving, press the power switch once.
- When the switch lock lamp ( ) blinks after the power switch is pressed, the shaver will not operate as it is locked. Hold the power switch for more than 2 seconds to unlock. (See page 14.)
Press the blades gently in the palm of your hand, mix the facial cleanser etc. around and move the blades up and down to make foam.
- If there is insufficient foam, add slightly more water, hot water or facial cleanser etc. to make it easier to create foam.

Notes

Do not use shaving agent (excluding foam), facial cleansing foam (with scrubbing compounds) or soap as these may cause the blades to clog, or be unable to make foam.

Shaving beard

Before shaving, check that the cleaning shutter is closed.

Press and shave.
- The “shaving sensor”, which automatically adjusts the power depending on the beard thickness, will operate.
  It will shave with high power on areas where the beard is heavy, and reduce the power on areas where the beard is thin, to reduce burden on the skin.
- Tips for better shaving
  Apply the whole system’s outer foil perpendicularly against the skinand shave by slowly gliding the shaver over the face against the grain of the beard.
- The beard under the chin and around the throat can be shaved better by stretching the skin so the beard will stand. 90°
- To prevent damaging the system outer foil, do not shave with only a part of the system outer foil.
Press when finished.
- When the battery capacity is low The charge status lamp ( ) blinks once every second when operating the shaver. The appliance beeps twice after being switched off.
- You can shave 2 to 3 times after the charge status lamp ( ) blinks. (This will differ depending on usage.)
- Using the trimmer
- Slide the trimmer handle up. Place at a right angle to your skin and move downwards to trim your sideburns.
- Tips for better usage
  Apply the trimmer edge perpendicular to skin gently and move downward slowly.
- - ```
        * Trimming sideburns
```
  - Pre-shave of long beards

Notes

After wet shaving, wash the main body with water and apply oil to the system outer foil.
Depending on the beard thickness or the amount of beard trimmings in the shaver head, the shaving sensor may not react and the driving sound may not change. This is not abnormal.
The shaving sensor may not respond depending on the type and quantity of the shaving gel or the quantity of the foam. This is not abnormal.

FAQ

Question

Will the battery deteriorate if not used for an extended period of time?
Can I charge the shaver after every use?
Why should the adaptor be disconnected after charge?
What is the constituent of the dedicated oil?
Why does the appliance beep twice after switched off?
Answer

The battery will deteriorate if not used for over 6 months, so make sure to perform a full charge at least once every 6 months.
The battery used is a lithium‑ion, so charging after every use will have no effect on battery life.
Charging the battery for more than 1 hour will not affect battery performance, but disconnect the adaptor for safety and to save energy.
Constituent of the oil is

liquid paraffin.

The sound indicates that the battery capacity is running low. Please charge the appliance.
