User Precautions
1.1 This product has AC110V/AC240V transfer switch.
Please conrm the supply voltage of the power grid before
using, pull the switch out to match the supply voltage of the
power grid. This product uses power plug and device appliance
coupler as disconnecting device of power supply in
power grid. When broken, it is fully disconnected power
supply and product electrodes. Convenient operation
should be maintained when using power plugs or device
appliance couplers.
1.2 In order to eectively protect this product, please use it
safely, and pay attention to the following:
1.2.1 Do not place bare ame sources, such as lighted candles,

User Precautions
1.2.2 Before use of equipment,
1) Please check that the power cord should not be
damaged, Matching use of power plug and power socket
connecting power grid, If it does not match, please replace
the appropriate power socket in time. No man-made destruction, modication and use shall be allowed.
2) The power supply of this product should be the
same as the voltage of the transfer switch, and the grounding
wire is independent and reliable.
3) The most suitable working environment for this
product is temperature: 5-28°, relative humidity is less than
90%. If the working time is long and the ambient temperature
is too high, eective cooling measures are recommended.
4) The power supply specications required by this
product are AC110V/60Hz or AC240/50Hz. If the voltage of
the power grid varies from high to low, and the uctuation is
relatively large, it is recommended to install the AC regulated
power supply device.
5) Before turning on the power supply, the volume
switch must be set to a minimum. After turning on, the volume switch should be slowly increased to prevent the instantaneous signal voltage shock from damaging the loudspeaker.
6) Before turning o the power supply, the volume
switch should be set to a minimum.
