Power Source

Charge

Plug in the USB socket on the back board with specialized charging cable (or other suitable cable), and
connect with charger of 5V, current is greater than or equal to 500 mA. (See in picture 2, position 7 ),
charging indicator is red, and will turn green when finished.

On/Off

(See in picture 1, position 3 ), power switch and function selection share the same knob, twist the knob to
OFF means turn off, and turn to FM/BT/AUX start corresponding function. The knob can be twisted either
clockwise or counter-clockwise.

Volume Adjustment

(Picture 1, position 4 ) Volume increase by twisting the knob clockwise and twisting
counter-clockwise to turn down.

Receive FM Broadcast

(Picture 1, position 3 ) Twist the function select knob to FM, and rotate the knob for radio station
selection to look for your favorite station.

Indicator emits green light when receive the radio station successfully, (picture 1, position 5 )
but never lights while the signal is weak.

Bluetooth Usage

(Picture 1, position 3 ) Twist the knob to BT (Bluetooth) function, then you will hear sounds “Di Di” for
matching preparation, while indicators (picture 1, position 5 ) flashes white light. Take out blue device
such as your cellphone, search the MUZEN OTR Metal Bluetooth, and click to connect.

The light keeps white after connected when you can open the player for music.

Usage for AUX INPUT

The radio is allowed to connect external signal (cellphone MP3, iPad, PC, etc.) with the standard
charging cable and signal line with 3.5mm socket. When using, twist the knob to AUX (picture 1,
position 3 ), indicator emits orange light (picture 1, position 5 ), which indicates broadcast signal.

Charging of OTR

OTR products are generally full charged within three hours, so please turn off the charger or pull out
the charging line after charging for three hours. There’s an indicator on the left side of the charging
port: red light means charging, green light means fully charged. OTR products have no standard
charging adaptor, you can use cellphone charger of 5V (500mA-2AI), or plug in a PC USB interface.

Durability of OTR Battery

The inner 1000mAH lithium polymer battery has passed UN 38.3 test, with greater capacity than most
Bluetooth speaker of the same volume, enables longer time for usage. Normal volume for usage:

Bluetooth 8-10 hours and reception 20 hours. Maximum volume for usage: Bluetooth ≥ 4 hours and
reception ≥ 10 hours (fully charged). Please note that, when taking OTR products on board, bring it

with you all the titme instead of by shipment, or it will be detected and confiscated.

Battery Replacement

Battery replacement is considered designing OTR products. The structure of inner battery installation
is available for replacement by manufacturer only. We will provide paid service for potential user. Do
contact us if necessary.

Charging and Using Simultaneously

OTR products is available for charging while using, however, the sound quality will be affected by
adaptor performance under Bluetooth status, and charging adapter is the switch power supply under
reception status, it will interfere the radio to receive signal, affecting reception performance. Thus, we
suggest do not charge while using OTR products.

Indicator Lights of OTR Products

MW-2 (radio function): reception——green (received successfully); blue, white, aux——orange;
charging——red; green——fully charged.

Band Switch of OTR Product

OTR band switch is tailored developed; please note that it’s 90 degree per gear, which is different from
the usual 30 degree per gear. No direction demand, either twist clockwise or counter-clockwise will do.

Radio Antenna

OTR products are designed to receive without using outside antenna.

Human Induction of OTR Radio

When the station signal is weak, it may be clearer by holding in hand, and becomes weak again
leaving hand. It’s called human induction, and more or less this problem exists in most radios.

6 Multi-functional USB Socket(Charge, AUX IN)

Bluetooth Connection

OTR products adopt CSR chip set, one of the best Bluetooth solution at present, with liable and stable
performance, receiving distance is within 5 meters. Some user complaint that failed to connect Bluetooth,
that's because too many Bluetooth connections exist in your cellphone (or iPad). Delete the existing
connections, reboot the cellphone, and re-connect OTR Bluetooth. However, if the devices are notebook,
PC or else that produced in early years when Bluetooth Protocol is imperfect, they may fail to re-connect.
And if the sound is not smooth in short distance, mostly because of the shared frequency interference
under the 2.4G OTR environment. Please swift to another environment or change Wi-Fi to the 5.8G
channel under this circumstance.

Low Volume under Bluetooth Status

Some feedback show that the volume is low after connecting with OTR products, while using network
signal like Spotify or Pandora. It’s common that the volume of player maybe closed or limited, just turn
up the volume. If the volume is still too low, delete the existing Bluetooth match and re-matched for
connection.

Waterproof

Because OTR products are not waterproof, so please pay attention to waterproof for use and moisture
proof in storage.

we will never be responsible for the result from using inferior charger. After usage, please turn off
the power.

Keep me well!

1. Use after fully charged, then I can sing for you.

2. Reception performance requires good using circumstance. When receiving radio
station, please be patient and twist the knob slowly, or you will miss other wonderful
shows.

Note: Keep away from interference source, be closer to the window when using indoor.
(Only for MW-2AI)

3. Each functional switch should be set on the right place when I use the radio, and be
aware of the volume in case making troubles to others.
