Check if the volume level is set on both the source device and
the speaker.
Check if the speaker is running out of power.
CHARGING
One full battery charge provides up to 12 hours of playtime at maximum volume
and up to 25 hours at 50% volume. When the battery is running low, you will
hear a voice signal.
TREBLAB HD7 may be used while charging in both Wireless Mode and 3.5 mm
audio cable mode.
To charge the speaker, plug one end of the cable into the Micro-USB charging
port under the rubber cover at the side of the speaker. Plug the other end
of the charging cable into a standard USB port. Regarding the adaptor power,
it takes from 2 up to 4 hours to fully charge the speaker’s battery.
If the speaker is turned OFF, the LED light will turn RED. If the speaker is turned
ON, it will start flashing RED and BLUE. The RED light will go OFF when the
speaker is charged.
Be sure to use a 5V DC, 0.5-1.5 A adaptor or charger. Using the power source
with lower power will increase the overall charging time.
