Voice Call
If Bluetooth voice calling is supported by your phone, turn the Voice recognition feature on, and your speaker as a
speakerphone.
1. Press and release the multifunction button once. You will hear a tone to indicate the voice function is
activated.
2. Say the name of person you wish to call clearly and slowly.
(Note: Speaker’s voice call function is determined by your mobile phone. Your phone must support this
function)
Battery charging and low-voltage alert
When the alert tone sounds every once 30 seconds and the red LED flashes, the battery of the Bluetooth speaker
is running low. It will automatically shut down if not charging it after 5-10 minutes. Charge the speaker immediately
with your smartphone charger adaptor through the USB to Micro-USB cable provided.
When the speaker is charging, the red LED will switch ON. The red LED will switch off when it is fully charged
after 2-3 hours.
Remarks
1. Pairing mode will last for 5 minutes. Other mobile phones cannot connect to the Bluetooth speaker during this
time.
2. Re-connecting automatically (includes two cases)
a. If the Bluetooth speaker is turned off, it will connect to the pre-set Bluetooth speaker automatically
when it is switched on.
B. When the MXSP-BT03 disconnects to mobile phone because it exceeds the effective range (typically
10 meters), the Bluetooth speaker will re-connect to mobile phone once it is back to the effective range
within 10 minutes. Longer than this, and it will need to be re-connected manually.
CHARGING INSTRUCTIONS
This unit operates on a built-in Li-ion battery that can be recharged either using the USB port on your computer or
from a USB power adaptor (not included) with a rated output of DC5V, 500mA and up.
Note: The micro USB CHARGING JACK located on this unit is only designed for charging the built- in Li-ion
battery.
CHARGING THE BATTERY FOR FIRST TIME
1.) Charge the built-in Li-ion battery a minimum of 2 hours prior to first use. Plug the unit into the USB port on
your computer or into a USB power adaptor (not included) using the included USB cable.
2.) The LED indicator will turn red while charging and turn blue when the unit is fully charged. Unplug the USB
cable from the power source once the battery is fully charged.
RECHARGING THE INTERNAL BATTERY
After prolonged use, the internal battery will become weak and the operation may become intermittent. When the
internal battery charge is very low, the Indicator LED will flash red and a melody will play alerting you to recharge
the internal battery as soon as possible.
Plug the speaker into a USB port on your computer or into a DC5V, 500mA and up USB power adaptor (not
included) using the included USB cable. Disconnect the USB cable from the speaker as soon as it is fully charged.
Charging in Power ON mode
The Indicator LED is RED while charging.
The Indicator LED will change from RED to BLUE when the battery is fully charged.
Note: 1. Charging time will vary if you are listening to music while charging the internal battery. We
recommend you switch off the speaker power during the charging process.
2. To prolong the life of a rechargeable battery, it is recommended to completely discharge it before
fully charging it again.
3. Rechargeable batteries need to be cycled for maximum performance and longer battery life. If
you don’t use the player that often, be sure to recharge the battery at least once a month in order
