BASIC RADIO OPERATION
TUNING MODE FAST TUNING SLOW
TUNING
The TUNING-FAST/SLOW button (8)
allows selection of fast or slow tuning
when using the tuning knob or the UP
and DOWN controls. FAST or SLOW
appear in the display. When tuning with
the tuning knob (28), fast tuning is usually
appropriate. When tuning with the UP and
DOWN buttons, use slow tuning to tune in
stations and fast tuning to move up or
down frequency at a rapid rate. Then use
slow to actually tune in stations.
Experiment with this control to see which
tuning mode that you prefer.
USING THE BANDWIDTH BUTTON
The BANDWIDTH button (14) is used
when listening to WM and SW stations.
Its purpose is to help minimize
interference. The preferred setting is
WIDE, which provides best audio fidelity.
Use NARROW when there is
interference. W or N will appear in the
display.
USING THE PL600'S SSB (SINGLE
SIDE BAND) FEATURE
SSB enables listening to shortwave
signals using the single-sideband mode.
This mode is used for a variety of signals
including amateur radio and other two-
way communications, Morse code,
weather-fax transmissions and other
encoded signals often referred to as
'utility' signals. To use SSB, turn on the
SSB circuit by pressing the SSB button
(13 ) . Note that SSB appears in the
display (42). Tune to the shortwave
frequency of your choice. Use the tuning
knob to coarse-tune the SSB signal, then
fine-tune with the SSB BFO+ knob (30).
This SSB circuit allows tuning of both
upper and lower sideband signals. For
best SSB signal clarity, placing the
DX/LOCAL switch in the LOCAL position
may be desirable.

INTRODUCTION TO SINGLE SIDE
BAND (SSB)
Many higher-end shortwave radios have
special circuitry enabling SSB, a highly
efficient way of electronically processing
transmitted and received signals for two-
way communication. Examples of this are
amateur radio (hams), maritime and
aeronautical communication. Either upper
side band (USB) or lower side band
(LSB) can be used. Non-voice methods of
communication can also be heard,
including CW (Morse code) and RTTY
(radio teletype). Receiving SSB signals is
not always easy. Since this is two-way
communications, transmissions are often
very short and sporadic. Also, most two-
way communication uses relatively low
power, 50 to 1000 watts. The amateur
radio operators are easiest to find, best
results are experienced when using an
outdoor shortwave antenna such as a
dipole.
Follow your radio's instructions on how to
engage its SSB feature. Shown next are
some selected frequency ranges on
which SSB communications can be
found. All frequencies are shown in
kilohertz.

5 CLOCK AND TIMER FEATURES

SETTING THE CLOCK

The factory has set the clock to function
as a 24-hour format clock.
There are three methods for setting the
clock.
CLOCK SET METHOD 1 UP AND
DOWN BUTTONS:
1. Turn the radio off. The clock digits
appear in the center of the display (34).
2. Press/release the button labeled 'Time'
(2). The clock's HOUR digits flash in
the display, within 5 seconds, set the
hour using the UP/DOWN buttons
(9, 10).
3. Press/release the 'Time' (2) button
again, the MINUTE digits flash in the
display, within 5 seconds, set the
minute using the UP/DOWN buttons
(9, 10).
4. Within 5 seconds of finishing,
press/release the 'Time' (2) button or
wait until the clock digits stop flashing.
CLOCK SET METHOD 2 –
NUMERIC KEYPAD:
1. Turn the radio off. The clock digits
appear in the center of the display (34).
2. Press/release the button labeled 'Time'
(2). The clock's digits flash in the
display.
3. Use the numeric keypad to key-in the
time in 24 hour format. Within 5
seconds of finishing, press/release the
'TIME' (2) button or wait until the clock
digits stop flashing.
CLOCK SET METHOD 3 TUNING
KNOB
1. Turn the radio off. The clock digits
appear in the center of the display (34).
2. Press/release the button labeled 'Time'
(2). The clock HOUR digits flash in the
display.
PL-600 OWNER'S MANUAL
3. Within 5 seconds, use the tuning knob
to set the hour.
4. Within 5 seconds, press/release the
'Time' (2) button, then use the tuning
knob to set the minute.
5. Within 5 seconds of finishing,
press/release the 'Time' (2) button or
wait until the clock digits stop flashing.
You can also set the clock when you turn
on the radio. When the radio is on, the
clock digits appear in the upper right
corner of the display. Set the clock
referring to the 3 methods above.
SETTING THE TIMERS (USE AS
WAKE-UP ALARM)
The PL-600 has two, independently
programmable timers, timer A and B,
enabling the PL-600 to turn on and play
the radio for an alterable period of time
and then turn off. The playtime can be
selected from 1~90 minutes. The timers
can be used as wake-up alarms. After
setting a timer and a playtime, store a
radio station into timer memory and
activate the timer. See the next sections
titled STORING A RADIO STATION INTO
TIMER MEMORY and ACTIVATING /
DEACTIVATING THE TIMER.
NOTE: A radio station must be stored into
timer memory. If this is not done, there
will only be static once the timer is
activated.
