MDR-IF540R
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
for schematic diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1
specified.
• C : panel designation.
• A : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 2.4 V and fed with regulated dc power
supply from battery terminal.
• Voltage is dc with respect to ground under no-signal
(detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F
: ANALOG
J
: RF
for printed wiring boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
: Through hole.
a
• : Pattern from the side which enables seeing.
(The other layer's patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from the
(Side B) pattern face are indicated.
Parts face side: Parts on the parts face side seen from the
(Side A) parts face are indicated.
