The shaver automatically adapts to all international direct and alternating current voltages (12 – 240 V 
/ 50 or 60 Hz) and all frequencies. The shaver can also be recharged on voltages below international standards in cars and boats, etc. However, a minimum 12 V outlet (direct or alternating current) is required. Recharging this way takes approximately 20 hours, and requires a special charging cord.
The surrounding temperature should not be higher than + 25 °C when recharging at 12 V, to ensure the proper functioning of the shaver.
A full charge will give you approxi- mately 35 minutes of cordless shav- ing.
Preserving the cell unit
In order to preserve the life of the cell unit, it should be fully discharged approximately once every 6 months by normal shaving and then fully recharged from the mains until the charging pilot light 1 goes off.
This procedure will condition the rechargeable cell unit, giving you the best possible shaving performance and prolonging the life of the re- chargeable cell unit.
The shaver should not be left in per- manent charge for several weeks.
Shaving with the mains lead
If your shaver’s rechargeable cell unit is flat (i.e. when you first use the shaver or the shaver runs out of power) you can connect the shaver directly to an outlet in order to shave immediately.
If the shaver should, however, not run immediately, leave it plugged in with switch 3 set to «off», for approxi- mately 1 minute. Thereafter, you can shave with the mains lead plugged into the outlet.
Shaving directly via the special charging cord while connected to outlets below international standard voltages (e.g. cars, boats, etc.) is not possible.
Shaving
Remove the foil protection cap 8 (a). Push switch 3 up to «on». Hold the shaver at right angles to your skin. Stretch your skin with your free hand
(b). Guide the shaver smoothly against the direction of beard growth, applying only gentle pressure.
Longhair trimming
To use
The longhair trimmer allows easy and exact trimming of the side burns (c). The longhair trimmer can be switched on and off during shaving.
Switching the shaver off
Push the on/off switch 3 back all the way to setting «off».
Important: After every shave replace the foil protection cap 8 on the foil frame 7.
Switch lock
To avoid accidentally switching on the shaver and discharging the cell unit, the switch lock should be turned on when travelling. Push switch 4 all the way down to the setting «lock».
