Important – Charging of batteries
If you are using rechargeable batteries, the batteries will
charge when the speakers are powered with the AC power
adaptors. The AC adaptors will charge rechargeable NiMH
or NiCd batteries. DO NOT attempt to charge any other
batteries except those specified above.
Remember to charge the batteries overnight (or over 10
hours) for fully charge. Battery life for operation is about 8
hours.
1. After powering up the speaker, the
power/RSSI indicator will start blinking in
green and orange color and searching for
transmitter.
2. If transmitter is found and connected, the
power/RSSI indicator will turn green.

3. Turn volume up on each speaker and you
should hear sound coming from the
speakers. Adjust the volume as desired.
4. For stereo operation, set the left/mono/right
switch to “left” on the speaker located to
the left of the listener, and set the other
speaker to “right” position. Set each
speaker to “mono” for mono operation.
IV. Audio Muting
When audio source is cut off for 3 minutes, the speaker will
be muted. But if audio signal resumes, the muting will be
disabled and speaker will be ON again.

V. Active/Passive Speakers
The 2.4GHz system can support infinite no. of
receivers(speakers or headphones). However, the no of
receivers increase, the performance will be downgraded,
i.e. transmission range will be reduced.
The first two receivers paired with the transmitter are called
“Active” speaker. The receivers paired later than the
Active Speakers are called “Passive Speaker”. For multi-
speakers system, the Active Speakers can maintain its
performance and is independent with the no of receivers in
the system.
If one Active Speaker is powered off, the other Passive
Speakers cannot be jumped into Active Mode
automatically. It has to be powered off first and then power
up again to make it “Active”.
