1. NEW/FORMER DISCRIMINATION
Three kinds of following distinguish methods exist.
• Distinguish method by serial number printed on the model
number label (Refer to right side for the serial number).
– Main unit (Bottom side) –
Model number label
Displayed characters/values
• Distinguish method by part No. printed on the KEY board
– KEY Board (Side A) –
Former type : 1-884-821-11
New type
• Distinguish method by LCD driver IC (IC901) on the KEY
board
– KEY Board (Side B) –
2. DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• X : Parts extracted from the component side.
• Y : Parts extracted from the conductor side.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen
(SIDE B) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(SIDE A) the parts face are indicated.
• Indication of transistor.

Note:
• All capacitors are in μF unless otherwise noted. (p: pF) 50

tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specifi ed.
• C : Panel designation.

• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : FM
• Voltages are taken with a VOM (Input impedance 10 M).
Voltage variations may be noted due to normal production
tolerances.
