Caution and tips on how to obtain the best results.
1. Before inserting the batteries, please make sure that they are inserted according to the correct
polarity.
2. The audio cable of VHF transmitters also serves as antenna. The length of the cable is cut according
to the specific frequency range. Do not alter the length or mix around the cable of different
transmitters. The use of wrong audio cable will affect the antenna efficiency of the transmitter!
3. Use only brand new Alkaline batteries. Do not use " general purpose " batteries, When batteries are
weak, replace all the batteries at the same time. Do not mix and use new and old batteries together.
4. Position the receiver such that it has the least possible obstructions between it and the transmitter.
Line of sight is best !
5. The transmitter and the receiver should be as close as possible but not less than 1m.
6. A receiver cannot receive signals from two or more transmitters simultaneously.
7. Turn the transmitter off when it is not in use. Remove the batteries if it is not to be used for a
period of time.
8. Antennas form an integral part of the receiver and must be installed when in Operation.
Simple DIY Trouble-shooting :
No sound when one speaks to the wireless microphone
Please verify the followings:
No sound when " CD / Digital Player with USB-Interface " is used
1. Main power switch should be ON. When no light appears, it means that the battery is weak. Please plug in
the AC cable to charge the battery.
2. CD volume control is turned on but Master volume control is not turned on.
1.Main power switch of the system should be ON. When power on LED not lighting up, it means that the
battery is either weak or not charged. Please plug in the AC cable to Charge the battery. The rechargeable
battery has a life span of about 2 years. If the batteries have reached their life expectancy, please change to
a fresh pair.
2.The power switch of the corresponding receiver module should be put to ON. This is indicated by the lighted
power LED. When two wireless microphones are used, both power switches of the receiver modules must
be ON.
3.Wireless microphone should be switched to ON and verify that the battery is okay. ( please refer to wireless
microphone operating manual ).
4.Please verify that the frequency on the wireless microphone and the corresponding built-in wireless
receiver module are exactly the same frequency group and channel.
5.Master volume control of the system should be turned on.
