HOWTO CHANGETHE CERAMIC FILTERS
This model is used two ceramic filters of CF2, CF3 and CF4.
You must use same type of color marked ceramic filters in order to
meet same specifications.
Therefore, the ceramic filter must change two pieces together since
it’s supply two pieces in one package as a spare parts.

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.

Choosing Power
Sources
Batteries (See Fig. A)
1 Open the lid of the battery case.
Slide fully in the direction of the arrow (B) on
the lid and lift it. Do not force to open it.
Doing so may damage the unit.
2 Insert four R6 (sizeAA) batteries (not
supplied) with correct polarity.
3Close the lid.
Battery life
Using Sony LR6(size AA) alkaline batteries:
Approx. 100 hours
Using Sony R6 (size AA) batteries:
Approx. 35 hours
Replacing batteries
When the sound becomes weak or distorted,
replace all the batteries with new ones.
Notes on batteries
•Insert the batteries with correct polarity.
•Do not charge the dry batteries.
•Do not use different types of batteries at the
same time.
•When you replace the batteries, replace all with
new ones.
•When the unit is not being used for a long
period of time, remove the batteries to avoid
damage from battery leakage and corrosion.
•If a battery leakage occurs, wipe the battery
compartment with a soft cloth before inserting
new ones.
HouseCurrent (SeeFig. B)
1Connect the AC power cord supplied to
the AC IN jack of the radio.
2Plug into a wall outlet.
Operating the Radio
1Press OPERATION ($) to turn on the
radio.
2Select a desired band, and tune in a
station using TUNING.
TUNE (tuning) indicator lights up
when a station is tuned in.
3Adjust the volume using VOL.
4Adjust the tone to your preference
using TONE.
To obtain clear treble, turn to “HIGH”.
To reinforce bass, set to “LOW”.
•To turn off the radio, press OPERATION (4).
•To listen with an earphone connect the
earphone to the v(earphone) jack.
The spearker is deactivated when an earphone
is connected.
•To improve Receiving condition(See Fig.C)
FM: Extend the telescopic antenna and adjust
the length and angle for the best reception.
SW: Extend the telescopic antenna vertically.
AM(MW)/LW : Since the reception is affected
by the direction of the radio, rotate the unit
horizontally for optimum reception.

•Due to standardization, replacements in
the parts list may be different from the
parts specified in the diagrams or the
components used on the set.
•RESISTORS
All resistors are in ohms.
METAL:Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F:nonflammable
•Abbreviation
IT : Italian model
•Items marked “*”are not stocked since
they are seldom required for routine service.
Some delay should be anticipated
when ordering these items.
•SEMICONDUCTORS
In each case, u : µ, for example:
