Voltage variations may be noted due to normal production
tolerances.

*CXS-GT4016F (US model) is Former type only.
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).
Model number label
Displayed characters/values
are example.
– Main unit (Bottom side) –
• Distinguish method by part No. printed on the KEY board
– KEY Board (Side A) –
Former type : 1-884-821-11
New type
: 1-884-821-21
or
1-884-821-22
• Distinguish method by LCD driver IC (IC901) on the KEY
board
