PRECAUTIONS

1. Handling precautions of CMOS IC

1. All MOS devices should be stored or transported in
materials that are somewhat conductive. MOS deivces
must not be inserted into conventional plastic snow"
or plastic trays:

2. All MOS devices should be placed on a grounded
bench surface and operators should ground them-
selves prior to handling devices, since a worker can
be statically charged with respect to the bench
surface.

3. Nylon clothing should not be worn while handling
MOS circuits.

4. When lead straightening or hand solderng is necessary.
provide ground straps for the apparatus used.

5. Double check test equipment setup for proper
polarity of voltage before conducting parametric or
functional testing.

6. All unused device inputs should be connected to VDD
or VSS'

2. De-Emphasis Switch (bottom panel)
W models are equipped with a 50 usec 7 75 usec selector
switch. This is set to 50 psec at the factory, but may
have to be reset to 75 usec depending on the area where
the unit is used,
Europe:
U,S.A.:

50 usec
75 sec

3: FM Tuning Step Frequency Switch (back panel)
W models are equipped with a switch to change the FM
tuning step frequency from 50 kHz to 200 kHz. These
units are set to 50 kHz at the facotry; change to 200 kHz
if this gives better results in your locality.
