FCC Statement

FCC INFORMATION

The equipment has been tested and found to comply with the limits for a Class B
Digital Device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction, may cause harmful interference to radio
communication. However, there is no grantee that interference will not occur in a particular
installation. If this equipment dose cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on , the user is
encouraged to try to correct the interference by one or more of the following measures:

--Reorient or relocate the receiving antenna.

--Increase the separation between the equipment and receiver.

--Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.

--Consult the dealer or an experienced radio/TV technician for help.

Notice:
The changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.

IMPORTANT NOTE:
To comply with the FCC RF exposure compliance requirements, no change to the antenna or
the device is permitted. Any change to the antenna or the device could result in the device
exceeding the RF exposure requirements and void user’s authority to operate the device.

1. Be sure to put the warranty label indicating purchase date on the boom of equipment to ensure your
interest in maintenance and service.

2. Product warranty, starting on the purchase date indicated on “warranty label”, will last for one year; if
the equipment does not have “warranty label”, the warranty period is 15 months from the manufac­turing date. If a microphone is broken but not sent back with the equipment, the warranty period is

15 months from the manufacturing date of the microphone.

3. Within the warranty period, if the equipment is broken under normal use as instructed in manual,
please contact the original selling store for repair.

4. When the product is returned for repair, to facilitate proper determination of cause of malfunction
and of whether repair fee is needed, please ship back the equipment and microphone together.

5. Within the warranty period, our company provides repair service at no cost except for the following
conditions that parts and repair may be charged:
a.Damages due to natural disaster or irresistible outside forces.
b.Damages due to drop, water, moisture, corrosion, foreign objects, missing components.
c.e warranty does not cover consumable parts. (such as microphone capsule, ball grille etc.)
d.ose without “warranty label” on equipment or with “warranty label” being damaged and failing to

identify warranty period.

6. Please keep the warranty properly. No replacement will be made if the warranty is missing.

Be sure to put store stamp and ll in purchase date for the warranty to be
