1. This system is a wireless communication product. The installation
location should have no blockage to avoid interfering with
transmission and reception. The distance between sender and
receiver should be greater than 30 metres to have every sender
transmit its best signal strength.
2. Check if the LED of transmitter & receiver module are lightening,
if DC-plug is inserted well and if there is power supply from
adapter, as the MP3 sounds are not to be received through horns
or earphones.
3. The AC adapter, which comes with this system, should not be
plugged into the same outlet with other appliances to reduce
interference probability.
4. Please send back to service dept, if problems are not able to be
solved.
NOTES FOR INSTALLING THIS SYSTEM
Federal Communication Commission
Interference Statement
This 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 instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does 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 of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
4. Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate
this 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.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth fo
r an uncontrolled environment. This equipment should be installed and
operated with minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter
