Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of soldering iron around 270˚C
during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

Setting the Clock
The display will flash “0:00”when the batteries are
installed or the AC power adaptor is plugged in for
the first time.
The clock can be adjusted when the radio is off.
1To stop flashing of the display, press
CLOCK (mb/CLOCK for ICF-M410S).
2While holding down CLOCK, turn
TUNE/TIME SET to set the clock to the
current time.
When you turn the control knob a little to or
, the clock digits move forward or back one
by one, and when you turn the control knob
further to or , the clock digits move
rapidly.
When you release CLOCK, the clock starts
operating, and “:”starts flashing.
24-hour system : “0:00”= midnight, “12:00”=

• All capacitors are in µF unless otherwise noted. p: pF.
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ωand 1/4W or less unless otherwise
specified.
•f: internal component.
•C: panel designation.
•A: B+ Line.
•H: adjustment for repair.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : FM
∗: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
