PL-365 

Functional Block Diagram

PL-365 is equipped with DSP si4735 microchips (from Silicon 
Labs in the USA) for digital demodulation of analog AM/FM 
broadcasting signals, which greatly enhances the radio's 
sensitivity, selectivity, S/N ratio and anti-interference.

IMPORTANT MATTERS FOR USING BATTERIES

1. When the device is not powered by batteries or the 
    adaptor for a long time, the clock setting is lost, but the 
    stored radio stations are saved. 
2. When battery power is low, the "      " symbol starts 
    flashing to alert you to charge the batteries or change to 
    new ones. The device turns off automatically when all 
    power is gone.
3. Do not mix new and used batteries, this may damage 
    the radio and display an incorrect power capacity.
4. If not using the radio for an extended period of time, 
    remove the batteries to prevent liquid leakage and 
    damage to the device.

USING THE INTELLIGENT CHARGING FUNCTION

 

Connect USB 5V to external 
power sources  

In power off mode, install 3 x UM3 (AA size) rechargeable 
(Ni-MH) batteries. Press & hold the [        ] button until
“               " and the  "Ni-MH Battery" symbol appear on the 
display. 

1. Use any 5V external adaptor with USB plug to connect 
    this radio, the symbol "     " will advance from  the bottom
    to top during power charging.  It stops when batteries are
    fully charged.
2. You can also use any USB cable 
    to connect the radio with your PC 
    for charging.

                                                                                        

Notes for charging power:

Do not mix new and used batteries, or batteries of different 
charging capacity.

Caution:

  Do not attempt to charge non-rechargeable 

batteries, this will damage both the device and the batteries.

TURN ON / OFF THE RADIO

1. Installing batteries    
    The battery compartment is located on the back of the 
    PL-365. To remove the battery compartment cover, apply 
    thumb pressure and slide it towards the bottom of the 
    radio. Install 3 AA size batteries into the battery 
    compartment, observing the battery polarity diagram on 
    the back of the radio.  Display screen would show battery 
    capacity, time, etc.

Note:  

If the radio is not able to be turned on.  Please check if the 
batteries were installed correctly, battery capacity is 
sufficient or the lock function had been applied with symbol
"       " displayed on screen.

TUNE INTO STATIONS

6

Short press [POWER] button to turn on your radio, then 
select your desired band by short pressing the [FM], [MW], 
SW [     ] or [     ] button.  In case of receiving FM/SW 
broadcasting, fully extend the telescopic antenna for a 
better reception.  
Now, you can tune into your favorite station with any of the 
below tuning methods:

Method 1: 

ETM (Easy Tuning Mode) 

The ETM function allows you to tune into stations easily 
and temporally store them into the ETM storage; 100 
stations for FM/MW & 250 stations for SW.

Note: 

 Scanned stations will not be stored in the regular 

450 memories, but will remain in the ETM temporary storage 
until next ETM scanning within each band.

HOW TO USE ETM

1. Turn on the radio and select 
    your desired band by pressing 
    either the FM, MW or SW 
    [    ] or [    ] button.
2. Short press the [ETM] button to 
    enter Easy Tuning Mode.
3. Long press the [ETM] button to 
    automatically scan all available 
    stations within the selected band.
4. When the scanning procedure is
    completed, turn the [TUNING] 
    knob to browse through the found 
    stations.
5. Short press the [VF/VM] button to
    exit the ETM mode.

Notes: 

FM station:  When you are in a different city or country, you 
should perform the ETM function again, because this will 
not delete any of the stations already within the memory.

SYSTEM SETTING

Frequency range setting for FM

Press & hold the [FM] button until 76-108MHz, 87-108MHz
or 87.5-108MHz appears on the display. Press the [FM]
button to select a suitable frequency range for FM.

MW(AM) step setting

Turn off the radio, then long press the [9/10k] button until
 "9 kHz" or "10 kHz" is displayed. 
The temperature unit display is associated with the MW 
tuning step. The temperature is shown in Celsius (C) when 
the MW tuning is in 9 kHz steps. Tuning steps of 10 kHz 
are associated with Fahrenheit (F). 

Turn On/Off LW

LW is only available in 9 kHz tuning steps. Therefore, 
before turning on LW, first assure the device is set to 9 kHz 
tuning steps. 
Then, long press the [MW] button and "MW 150 - 1620" is 
displayed to confirm that LW has been turned on.

    stations for about 5 seconds. 
3. To stop auto browse function, 
    simply press the [VF/VM] button.

MW station:  It is recommended to perform the ETM 
function during day time as well as night time, because 
there usually are more stations that start broadcasting at 
night

SW station:  It is recommended to perform the ETM 
function in the morning, afternoon as well as night time, 
because the transmitting signal of SW is very unstable and 
there usually are more stations that start broadcasting in 
the late afternoon.

Method 2: 

MANUAL TUNING

Turn on the radio, short press the [VF/VM] button to switch 
into frequency mode.  Rotate the [TUNING] knob to select 
your station.

WORKING WITH MEMORIES  

The PL-365 has 550 station memories: FM (100), MW (100), 
SSB (100) and SW (250).

Method 1:  

ATS - Auto Tuning Storage

To automatically store all available 
stations, first select the frequency 
band in which to perform ATS. 
Then press & hold the band button 
(e.g. [FM] or [MW]); "PRESET" will 
flash in the top right corner of the 
display while the frequency starts 
running. The frequency stops 
running once the ATS operation 
has completed. Rotate the [TUNING] 
knob to browse all stored stations.

There are two modes for SW ATS function:
Mode A: In SW band, long press the [A /     ] button to ATS 
              the stations within all meter bands.
Mode B: In SW band, long press the [B /    ] button to ATS
              the stations within present meter band only.

Note: 

When performing ATS in FM, MW or SW (mode A), all 
previously stored stations will be replaced.

When performing ATS in SW (mode B), previously stored 
stations are not replaced; newly found stations are stored in 
blank SW memory positions.
