TREBLAB HD-Force - Page 18

Once plugged in, the battery level indicators will start flashing slowly showing
the current battery level (for more details, please check the BATTERY LEVEL
INDICATION section). This means that the speaker is charging. When the speaker
is fully charged, all tree battery level indicators will stop flashing and become
steady.
Be sure to use a 5V DC, 0.5-2A adaptor or charger. Using the power source with
lower power will increase the overall charging time.
Unplug HD-Force from the charging cable and the cable itself from the power
source when not in use.
If the speaker is left unused, even the fully charged battery will lose its charge
over time. We recommend fully charging the HD-Force speaker at least twice a
month to maintain sufficient battery life.
