Notes On Handling Optical Block Assembly - Sony PDW-HD1500 Maintenance Manual

1-14. Notes on Handling Optical Block
Assembly
To prevent the damage due to the electrostatic charge, be
sure to put the following grounding while handling the
optical block assembly (KES-330A).
Grounding for the human body
Be sure to put on an antistatic band for grounding (with
Z) whose other end is grounded.
impedance lower than 10
8
n
Because static electricity charged on clothes is not drained
away, be careful not to touch your clothes to the optical
block assembly.
Grounding for the work table
Be sure to place the optical block assembly on an antistatic
mat (with impedance lower than 10
copper sheet for grounding.

Precautions
. The optical block assembly is a precise unit. Be careful
not to subject it to shocks by dropping or rough han-
dling.
. Do not touch the objective lens.
. Hold the slide base (die casting part) and the connector
on the board when handling the optical block assembly.
Do not touch the circuit on the print board with your
hand or a substance directly; otherwise, the circuit may
be damaged.
. The performance of the actuator may be affected if a
magnetic material is located nearby, since the actuator
has a powerful magnet.
Keep magnetic substance away from the actuator. if the
magnetic force makes a metallic material such as a
screwdriver and so on hit the actuator, the objective lens
will be damaged.
. Do not allow foreign materials to enter through gap in
the cover of the actuator.
