6. HANDLING INSTRUCTIONS

 Usage and storage in dusty, hig h temperature and high humidity environments should be avoided.  To avoid damage to the LDGU by electrostatic discharges, measuring equipment and operators

must be grounded during handling (see fig. 18). The user of this unit must take all necessary precautions to avoid ESD (Electro-Static Discharge) failures duri ng handling and assembly of this unit into the end product.

 Contamination of the objective lens will influence the performance. Avoid fingerprints on the lens,

handle the mechanism in a clean environment.

 The actuator with lightpath has been adjusted carefully during manufacturing. High forces on this

part may damage the unit and have to be avoided.

Avoid touching this part!! Do not disasse m ble or r e adjust !!

 Safety: The (invisible) laser beam may damage the human eye. Avoid that people can look

directly or indirectly into the objective lens when the power is switched on.

 Fast heating up (e.g. by bringing the mechanism from a cold place into a warm and hum id room)

can result in moisture condensing on the lens, thus influencing the playability for a certain time. Before checking the performance the mechanism should stabilise for at least 4 hours. See also the recovery times mentioned in UAN-D 1590.

 Please keep the short circuit clip on the flex foil mounted as long as possible. Remove just before

installing the CD mechanism in the final application to avoid the risk of damage by electrostatic discharges.
