4-3. SCHEMATIC DIAGRAM — BASE MAIN SECTION (1/2) —

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 diagrams

•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 1/4 W or less unless otherwise specified.

•C : panel designation.

•U : B+ Line.

•Power voltage is dc 9 V and fed with regulated dc power supply from external power voltage jack. (BASE PHONE)

•Power voltage is dc 12 V and fed with regulated dc power supply from J1008 with 100 Ω in series. (BASE PHONE)

•Power voltage is dc 3 V and fed with regulated dc power supply from battery terminal. (HANDSET)

•Voltage is dc with respect to ground under no-signal condition.

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

•Signal path.

N : TX (To Tel Line)

O : RX (From Tel Line)

P : bell

For printed wiring boards

•X : parts extracted from the component side.

• : Carbon pattern.

•z : Through hole.

•b: 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.
