Powering Your Device
This device is powered by a BL-5C 3.7V rechargeable lithium (Li-ion) battery.
Open the battery compartment and install the battery following the directions
as indicated on the battery door. The device can also be powered by
connecting a DC 5V/0.5A power adapter to the USB-C socket.
Note: Connecting an external power supply causes interference when listening
to radio frequencies. If experiencing reception difficulties, disconnect the
external power supply and use a battery instead.
Attention! If you use a power adapter, assure that is appropriately certified
and meets the standard requirements for an adapter in your region.
Charging the Battery
When the battery icon is displayed as “ ”, this indicates that battery power
is about to run out. Please charge it in time. To charge the BL-5C rechargeable
lithium (Li-ion) battery, connect a DC 5V/0.5A charger to the USB socket on
the left side of the radio using a USB-C charging cable. When charging, the
charging time is displayed at the top right corner of the display while the
“Charge” indicator flashes. When charging is complete, the battery symbol is
displayed as “ ” and the charging indicator "Charge " stops flashing.
Notes:
Assure that the charger is appropriately certified and meets the standard
requirements in your region.
To avoid electrical noise interference, it is recommended not to charge the
battery and listen to radio broadcasts at the same time.
If the device is not used for a prolonged period of time, it is advisable to
charge the battery once every 3 months for about 4 hours. This may
extend battery life.

Setting the Clock (24-hour format)
1) Press and hold [ TIME ] until the clock time starts flashing.
2) Use the numeric keys to enter the current time (hours + minutes is four
digits), or rotate the [ TUNING ] and [ VOLUME ] knobs to adjust the time,
and then press [ TIME ] to confirm the setting.
Setting the FM Frequency Range
With the device off, set the frequency range to correspond with the country
in which you are using the radio. Press and hold [ 1 ]. The display will show
“ ”, “ ”, “ ” or “ ” to indicate the corresponding range:
64 ~ 108MHz, 76 ~ 108MHz, 87 ~ 108MHz or 88 ~ 108MHz. Quick press
[ 1 ] repeatedly to select your preference.
Setting the MW (AM) Frequency Range and Tuning Step
With the device off, set the frequency range of MW (AM) to correspond with
the country in which you are using the radio. Press and hold [ 3 ].
Display indicates “ ”: MW frequency steps are set at 9 kHz, and the
frequency range is 522~1620 kHz (suitable for Asia, Europe, Africa,
Oceania).
Display indicates “ ”: MW frequency steps are set at 10kHz, and the
frequency range is 520~1710 kHz (suitable for North America and South
America).
Enabling/Disabling Longwave (LW)
With the device off, press and hold [ 2 ], the display shows “ ” (enabled)
or “ ” (disabled). To select the LW frequency band, power on the device
and then quick press the [ MW/LW ] button twice.

USING THE DEVICE
6
Turning the device on/off: Quick press the [ POWER ] button.
Using headphones (caution!): Connect headphones with the volume set low
and increase if required. To prevent possible hearing damage, do not listen at
high volume levels for long periods.
Volume control: Rotate the [ VOLUME ] knob upwards to increase or
downwards to decrease the volume level.
VF (View Frequency) and VM (View Memory)
Press the [ VF ] button to enter the frequency mode. VF is used when
searching for new radio signals.
Using the Radio's Antennas
FM / Shortwave (SW): When listening to FM or shortwave radio, extend the
antenna and adjust its length and direction in order to get the optimum
reception. You may also choose to connect an external antenna by
connecting it to the [ FM & SW ANTENNA ] socket (3.5mm).
Caution! Waterproof and lightning protection measures must be taken when
using outdoor antennas.
Medium Wave (MW) / Long Wave (LW):
This radio uses an internal ferrite bar antenna to receive medium wave and
long wave broadcasts, the quality of which can be enhanced by changing
the position and direction of the device.
Press the [ VM ] button to enter the memory mode. VM is used for recalling
previously stored stations. The radio indicates how many stations of
the selected frequency are already stored into the memory. If no stations
have been stored, the display indicates “ “.
