1.1. Location of control
1. Speaker
2. Telescopicantenna
FM :Pull out the telescopicantenna and adjust its length and
anglefor optimum reception.
MW :The sensitive ferrite core antenna inside the unitwill provide
excellent MW reception inmost areas. For optimum reception,
turn the unitinthe direction which gives the best results, since
the ferrite core antenna isdirectional.
SW :Extend the telescopicantenna fullyand keep itvertical.
3. Tuning control
4. Earphone jack
-Avoidlistening for prolonged periods of time to prevent
hearing damage.
-The speaker isautomaticallycut off when an earphone is
connected.
5. On-off/volume control switch
Turn clockwise to switch the radioon, and adjust the volume level.

1. Thissection describes procedures for checking the operation of
the major printed circuitboards and replacing the main
components.
2. For reassemblyafter operation checks or replacement, reverse
the respective procedures. / Special reassemblyprocedures are
described onlywhen required.
3. Select items from the following index when checks or
replacement are required.

-The voltage value and waveforms are the reference voltage of this
unitmeasured byDC electronicvoltmeter (high impedance) and
oscilloscope on the basisof chassis. Accordingly, there mayarise
some error involtage values and waveforms depending upon the
internal impedance of the tester or the measuring unit.

-Importance safetynotice :
4

Components identified bymark have special characteristics
important for safety. Furthermore, special parts which have
purposes of fire-retardant (resistors), high-qualitysound
(capacitors), low-noise (resistors), etc. are used. When replacing
anyof components, be sure to use onlymanufacturer's specified
parts showninthe parts list.
Caution !
IC, LSI and VLSI are sensitive tostatic electricity.
Secondarytrouble canbe preventedbytaking care during repair.
-Cover the parts boxes made of plastics with aluminium foil.
-Put aconductive mat on the work table.
-Ground the soldering iron.
-Donot touch the pins of IC, LSI or VLSI with fingers directly.

-The parenthesized indications inthe Remarks columns specifythe
areas or colour. (Refer to the cover page for area or colour)
Parts without these indications can be used for all areas.
-Capacitor values are inmicrofarads ( F) unless specified
otherwise, P= Pico-farads (pF), F= Farads.
-Resistance values are inohms, unless specified otherwise, 1K=
1,000 (OHM).
-The marking (RTL) indicates that the Retention Time islimited for
thisitems. After the discontinuation of thisassemblyin
production, the item will continue to be availablefor aspecific
period of time. The retention period of aavailabilityisdependent
on the type of assembly, and inaccordance with the laws
governing part and product retention. After the end of thisperiod,
the assemblywill no longer be available.
