FCC FREQUENCY: 480.100~529.850 MHz
UHF Frequencies Available for Use for Home Electronics in
North America
The radio frequencies used in the transmission of wireless
information are closely regulated in most countries including
North America. A lot of countries strictly enforce their
regulations stating which frequencies are available for use for
certain device, so it can help limit the amount of radio
frequency interference in all wireless communications.
Please refer to the following table for MIC 1 and MIC 2
frequencies. If the frequencies indicated in the following table
are in conflicts with the local wireless information law, please
switch to a different product model.
FCC Information to User for Reference
This equipment is designed in compliance with the limits for a
Class A digital device pursuant to part 15 of the FCC Rules
from the United States of America. These limits are designed to
provide protection against harmful interference when the
equipment is operated in public environment. This equipment
generates, uses, and can radiates radio frequency energy
and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential
area may cause harmful interference, and users will have to
correct the interference at their own expense.
Appendix
15. NOISE COMING FROM MICROPHONE
CAUSE:
There is interference in the area.
REMEDY:
•
Change the frequency on the microphone and receiver.
•
Stand further away from speakers.
• Check the amplifier status and adjust microphone and music
volumes.
16. THE MICROPHONE SUDDENLY HAS NO SOUND AND
THE AMP/RECEIVER LCD IS OFF.
REMEDY:
Make sure the power cable is properly connected
to the amp/receiver and securely plugged into the electrical
outlet. Make sure the AC electrical outlet works and supplies
the proper voltage.
17. THE MICROPHONE SUDDENLY HAS NO SOUND BUT
THE RECEIVER SHOWS RF SIGNAL.
CAUSE:
The microphone wire is damaged or disconnected.
REMEDY:
Open the microphone head cover to check the wire
and reconnect the wire. If it does not work, replace the
microphone head.
18. THE MICROPHONE DISTORTION LEVEL IS INCREASING
GRADUALLY.
CAUSE:
The microphone batteries are running out.
REMEDY:
Replace the microphone batteries.
19. POOR SIGNAL
When the amp/receiver and microphone are placed in
different rooms seperated by a wall, this would cause poor
signal. Your audio equipment is close to the police, fire or
radio stations. In this case, a different frequency MUST be
selected.
20. AUDIO FEEDBACK
REMEDY:
• Turn down the dB on the equalizer especially 1K, 2.5K,
5K, and 10K Hz.
• Turn off the Mix Excite.
21. AMPLIFIER SHUT DOWN/INTERFERENCE NOISE
CAUSE:
The amplifier powered on but there is no music
output.
REMEDY:
Make sure that the AC-power supply is connected
to the correct voltage level.
22. NOISE AND DISTORTION
When humming noise or displeasing sound appears, you can
replace the supplied power cord with an AC power
cord with a magnetic device.
