Flexible Circuit Board Repairing
@® Keep the temperature of the soldering iron around
270°C during repairing.
@ Do not touch the soldering iron on the same conduc-
tor of the circuit board (within 3 times).
®@ Be careful not to apply force on the conductor when
soldering or unsoldering.
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.

Two R6 (size AA) batteries with
correct polarity
Installing Batteries EJ
insert two R6 (size AA) batteries with correct polarity. When you insert the
batteries for the first time, 0:00 flashes in the display window. To stop flashing,
press ENTER/CLOCK.
Knowing when to replace the batteries
When the batteries become weak, the radio is turned off, the time indicator
appears and “cq” flashes in the display window. (The sound may become weak
or distorted before “‘csa” starts flashing.) Replace both batteries with new ones.
Even after you replace the batteries, “cosa” remains flashing. To turn off “cs”,
slide AUTO OFF/POWER.
Replace the batteries within about 60 seconds after turning off the power.
If more than 60 seconds has passed, the preset stations are canceled and the
time indicator shows 0:00.
In this case, perform the clock setting and preset tuning again.
Notes on the battery
¢ Insert the batteries with correct polarity.
* Do not mix new and used batteries.
e The batteries cannot be charged.
* To avoid damage from possible battery leakage, remove the batteries when the
unit will not be used for a long time.
* Concerning the battery life, see “Specifications”.

If this happens, try again from step 3.
Tuning in a Preset Station jj
1 Turn on the power.
2 Select the band, FM or AM.
3 Select the desired preset number by pressing
the PRESET + or — button.
4 Adjust VOLUME.
To change the preset station
Tune in the desired station to be newly preset.
Preset the tuned station to the desired button.
The station previously preset to that button is

To Improve Radio Reception
FM: Extend the telescopic antenna and adjust
the angle of the antenna so that the FM
sensitivity will be increased.
AM: A ferrite bar antenna is built in for AM
reception. Rotate the unit horizontally for
optimum reception.
If the FM stereo program is noisy
Usually set STEREO/MONO to STEREO. You
can receive the FM stereo program in stereo,
using the earphones. When the signal is
weak and noisy, set it to MONO. There will
be no stereo effect, but the sound will
improve.
