4. Memory Preservation

This unit does not require memory preservation batteries. A
built-in memory po wer back-up system preserves the contents
of the memory during power failures and even when the unit is
unplugged. The unit must be plugged in order to charge the
back-up system.
The memory preservation period after the unit has been
unplugged varies depending on climate and placement of the
unit. On the average, memory contents are protected over a
period of a few weeks after the last time the unit has been
unplugged. This period is shorter when the unit is e

xposed to a

highly humid climate.

5.Setting the voltage selector
(Worldwide models only)

Worldwide models are equipped with a voltage selector so
that you

NOTE

.
.

THE COMPONENTS IDENTIFIED BY MARK ! ARE CRITICAL FOR SAFETY.
REPLACE ON LY WITH PART NUMBER SPECIFIED.

.

VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE (NO INPUT SIGNAL)
ELECTROLYTIC CAPACITORS ( ) ARE IN uF/WV.

.

ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED.

.

EX) 030-3pF 330-33pF 331-330pF 333pF-0.033uF
ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED.

.

THE THICK LINE ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
