PRODUCT SAFETY NOTICE
Each
precaution
in
this
manual
should
be
followed
during
servicing.
Components
identified
with
the
IEC
symbol
A\
in
the
parts
list
and
the
schematic
diagram designate
components
in
which
safety
can be
of
special significance.
When
replacing
a
component
identified
with
A,
use
only
the
replacement
parts designated,
or
parts
with
the
same
ratings
o/
resistance,
wattage
or
voltage
that
are
designated
in
the
parts
list
in
this
manual.
Leakage-current
or
resistance
measurements
must
be
made
to
determine
that
exposed
parts
are
acceptably
insulated
from
the
supply
circuit
before returning
the
product to the
customer.
NOTES:
1. Aliresistors values are indicated in “ohm? (K=107, M=104).
2. Alicapacitors values are indicated in “uF” (P=107'?).
3. Allvoltages indicated an the schematics are measured under the
following conditions. :
b. Ali voltages +10 % with respect to chassis ground
c. No signals at input terminals
d. AC input at 220 volts 50 Hz
4. This is a basic schematic diagram.
a. Use aV.T.V.M.
Because
Fisher
products
are
subject
to
continuous
improvement,
Fisher
Corporation
