Electrical Safety after repairs
General Part
According to the Product Liability Laws, the Manufacturer is responsible for ensuring that the product presents no
danger to the user when used correctly. This risk is especially important with products which are operated from the
mains voltage supply. To ensure that safety parameters are maintained especially after repairs have been carried
out, it is imperative that the product is tested as specified in a recognised Test Procedure.
1. Products conforming to Safety Class I (earthed, Symbol )
Earth lead Test.
Check that the earth lead performs its function by using a Continuity Tester. For this integrity of the connection
(conduction of current) from the protection lead contact in the plug to all metal parts that can be touched, with the
product switched on and with it switched off, must be proved. A maximum of 0.3Ω is permitted for the resistance of
a connecting lead with a length of up to 5 metres.
2. Products conforming to Safety Class II (insulated, Symbol)
Insulating resistance measurements as specified in VDE 0701/Part 200.

LASER Safety
The MOS safety requirements must be met because many components, particularly the laser diode, are very
sensitive to static electricity.
The pick-up unit incorporates many precision components and should therefore be protected against high
temperatures, high humidity, strong magnetic fields, mechanical shocks and dust.
– The CD Player belongs to the category of products with a low-power LASER.
– According to DIN VDE 0837 or IEC 825 it is a Class 1 LASER meaning that the output power limits are determined
by the design. The LASER DIODE must not be operated outside the pick-up since the output power increases
by many times (Class 3B) and will cause injuries to the eye. In this case the use of LASER protective goggles
is strictly recommended.
– Due to the lens system of the LASER pick-up the focal point of the LASER light is about 1.5mm above the focus
lens. The focal point is located low enough to allow the LASER to be looked at with unprotected eyes.
– Avoid looking at the LASER using external optical means such as, for example, a magnifying glass because the
focal point will be projected onto the retina and may cause injuries to the eye.
– The LASER light appears on the focus lens of the pick-up as a dark-red spot when looking at the optical system
at an angle, preferably at low ambient brightness.
– By placing a sheet of transparent paper onto the focus lens the LASER spot is projected onto the back of the sheet
and is well perceivable.
In general, built-in safety locks ensure that the LASER does not operate with an open disc compartment
cover. In consideration of the above instructions, the special safety locks can be made ineffective and
the LASER will be visible as a small red spot.
Safety Standard Classes for the LASER (according to DIN IEC 825 / VDE 0837)
Class 1
Not dangerous for the human eye. Maximum output power eg: at 700nm…69µW.
General Part
CLASS 1
LASER PRODUCT
Class 3 B
Dangerous for the human eye and, in special cases, for
the skin. Maximum radiation power up to 0.5W.
FALLS ERFORDERLICH
IF APPLICABLE
HVIS NØDVENDIG

The output of laser light from a CD pick-up unit
corresponds to Class 1. If the laser diode is
operated outside pick-up unit, this corresponds to
operation under Class 3 B.

Handling of MOS Chip Components
Circuits containing MOS devices require special and careful handling to protect them from damage by static charges.
Static charges can build up on all highly insulated plastics, can be transferred to persons wearing clothes and shoes
made from synthetic materials and from them to the MOS devices.
Protection circuits in the inputs and outputs of MOS devices provide only a limited degree of protection and this is
due to their reaction time.
Please observe the following instructions to protect these components from damage by static charges:
1. Retain MOS components in their conductive packages until they are required for use. MOS components must
never be stored or transported in Styroper materials or in plastic magazines.
2. Personnel handling MOS components must first discharge any electrostatic charge on their body or clothing by
touching a grounded object.
3. Handle the MOS device by the body and do not touch the terminals / pins.
4. Use earthed instruments only for testing and processing purposes.
5. Removal of, or making contact with, MOS ICs fitted into sockets must only be carried out with the operating voltage
disconnected.
6. Circuits containing p-channel MOS components must not be connected to positive voltages (with reference to
the substrate connection VSS).
MOS Soldering Instructions
• Use mains-isolated low-voltage soldering irons only.
• Maximum soldering period is 5 sec with a soldering iron temperature of 300°C to 400°C.

CHIP Technology
Soldering and unsoldering of CHIP components
– Use only low-voltage soldering irons with temperature control.
– Permissible soldering temperatures are approx. 240°C up to max. 300°C.
– Keep the soldering period as short as possible.
– Keep the CHIP components in their original packages until they are used to avoid oxidation of the end contacts.
– Do not touch CHIP components with bare hands.
Unsoldering of CHIP components
1. step: Clean the CHIP soldering point with a solder wick (Fig. 1).
2. step: Warm up the ends of the CHIP or the whole CHIP component and remove the CHIP from the adhesive by
turning it without application of force so that the tracks beneath the CHIP do not break (Fig. 2).
Attention! Never use unsoldered CHIPS again!
Soldering of CHIP components
3. step: Remove any remaining residues from the soldering point. Then apply a bead of solder (Fig. 3).
4. step: Place the CHIP onto the soldering point, then center and fix it (Fig. 4).
5. step: Solder the free end of the CHIP and resolder the first soldering point after it has cooled (Fig. 5).
The conductive layer may be broken.
