Can't pair when four transmitters need to be paired with a
receiver
① Make sure that the transmitters are paired with the receiver
one by one, not at the same time. Only when a transmitter is
paired with the receiver, can the second transmitter be paired
with it.
② If a transmitter fails to be paired with a receiver, turn the
transmitter off and press and hold its power button for 5
seconds to pair again.
Charging case can’t charge the transmitter(s) or receiver
① If the remaining charge of the charging case is too low, please
recharge the case. Try again.
② Wipe the charging contacts on the transmitter(s), receiver,
and charging pins in the case with a clean cloth. Make sure
there is no dirt covering them.
③ If the touch points are not firmly connected due to a lack of
magnetic force, please contact BOYA after-sales support.
The indicator doesn't display charge status
Only if the transmitter and receiver are turned off, do their
indicators display the charge status while charging.
