Explanation of symbols
Symbols on the adapter and the device
- This symbol indicates that the adapter is double insulated (Class II),
according to IEC 60601-1 (Fig. 2).
- This symbol means: Do not throw away with the normal household
waste. For further instructions, see chapter ‘Recycling’ (Fig. 3).
Symbols on the device
- This is the symbol for serial number. This symbol is followed by the
manufacturer’s serial number (Fig. 4).
- This is the symbol for reference number. This symbol is followed by
the manufacturer’s reference number, which is the type number of
the device (Fig. 5).
- This symbol on the device means: protected against access to hazardous
parts with a finger and against vertically falling water drops when tilted
up to 15 degrees (Fig. 6).
- This symbol means that the part of the device that comes into physical
contact with the user (also known as the applied part) is of type BF
(Body Floating) according to IEC 60601-1. The applied parts are the
electrodes (Fig. 7).
- This symbol means that this device emits non-ionising radiation.
All devices and systems that include RF transmitters or that intentionally
apply RF electromagnetic energy must have a label with this symbol (Fig. 8).
- This symbol means: caution TENS output. You find this symbol near all
electrode connections (Fig. 9).
- This symbol means ‘Manufactured by’ and appears next to the address
of the legal manufacturer (Fig. 10).
- This symbol means: Conforms to EC Directives. CE stands for ‘Conformité
Européenne’. 0344 is the number of the notified body (Fig. 11).
- This symbol means: read the user manual before you start using
the device (Fig. 12).
- This symbol is the mark that identifies the standby button (Fig. 13).
- This is the pulse symbol. It appears next to the status indicator (Fig. 14).
- This is the battery symbol. It appears next to the battery indicator (Fig. 15).
Symbols on the adapter
- This symbol means: alternating current (Fig. 16).
- This symbol means: direct current (Fig. 17).
- This symbol means: Conforms to EC Directives. CE stands for
‘Conformité Européenne’ (Fig. 18).
- This symbol means: may only be used indoors (Fig. 19).
- This symbol means: USB connector (Fig. 20).
- This symbol means: micro-USB connector (Fig. 21).
- This symbol is the certification logo that includes identification of the
accredited compliance test house. (Fig. 22)
- This symbol is the certification mark for technical equipment.
The GS mark is based on the German Equipment and Product Safety
Act (Fig. 23).
- This symbol shows that the no-load power CEC (California Energy
Commission) Efficiency Level is V (five) in order to meet EU
requirements (Fig. 24).
Symbols on electrode bag
- This symbol means: Do not use while driving, operating machines or
performing other activities that may present a risk of injury (Fig. 25).
- This symbol means: Do not use damaged or worn electrodes or
electrodes that have lost their adhesive power (Fig. 26).
- This symbol means: The electrodes should be used by one person and
not shared with others (Fig. 27).
- This symbol means: Do not place the electrodes on top of each other
or so close to each other that they touch each other (Fig. 28).
- This symbol means: Do not place electrodes on your head or on
your neck (Fig. 29).
- This symbol means: Do not place the electrodes on your chest (Fig. 30).
- This symbol means: Do not put the electrodes on open wounds,
cancerous lesions, rashes and infected or inflamed skin (Fig. 31).

Replacement
Electrodes
Replace the electrodes if:
- they are damaged or torn.
- they are past the use-by date indicated on the resealable bag.
- they have lost their adhesive power. Never use plaster or tape to attach
them to your skin.
- stimulation feels less strong.
- when stimulation is uncomfortable, i.e. when you experience an
unpleasant stinging or biting sensation.
Note: Always replace the electrodes with electrodes recommended for this device
by the manufacturer. You can order new electrodes at www.philips.com/
