RadioFans.CN 2 TABLE OF CONTENTS ICF-M410S 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 270C 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. 1. GENERAL 3 2. DISASSEMBLY 4 3. ELECTRICAL ADJUSTMENTS 5 4.

SECTION 1 GENERAL * Telescopic Antenna TUNE/TIME SET VOL DC IN 4.5V v jack 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” = noon RadioFans.CN 4 ICF-M410S SECTION 2 DISASSEMBLY Note :Follow the disassembly procedure in the numerical order given. 9Screw (+PTPWH 2 8) 1Screw (+B 3 6) 3Five screws (+BTP 3 14) q;Two screws (+P 2 8) qfTwo screws (+P 2 8) 6Screw (+PTPWH 2.6 8) 7Side panel (L) qsSide panel (R) qdArm (jog) 8JACK board qgKEY board qjMAIN board qhKnob 2Antenna, telescopic Cabinet rear 4Claws qaClaws Remove the Claws Remove the Claws Knob (jog) 5Plate, contact Cabinet (front) sub assy RadioFans.CN 5 ICF-M410S SECTION 3 ELECTRICAL ADJUSTMENTS BAND : MW/SW Repeat the procedures in each adjustment several times for the maximum level meter indication.
