Speaker Operation
The speaker can be powered as follows:
By the AC adaptor (contained in the box). (This is always
required for the first time charge).
By the Solar Panel (approximately 30,000 lux required).
Make sure you turn on the transmitter on channel 1, 2 or 3
before turning on the speaker and adjust the channel on the
speaker as on the transmitter.
If the signal turns weak or interference happens, change the
channel or tune into a different channel on both speaker and
transmitter.
For maximum volume, operate your music source on high
then adjust the volume up/down on the speaker/remote
control.
