Basic Troubleshooting.
SolutionIssue
Please check gain levels.
Please check cable connections.
Audio light glows but
no Sound.
Distortion or unwanted
noise bursts
Remove nearby sources of RF interference (CD players, computers, cell
phones, digital effects, in-ear monitor systems, etc.)
Reduce transmitter gain. Replace transmitter battery.
If using multiple systems, change the channel of one of the active systems.
Avoid using two systems with the same frequency at the same place;
please separate them at least by 200 meters.
1. Grille: It protects the Diaphragm from
damages. Also acts as an effective wind
& pop filter.
2. Power ON/OFF & Mute SWITCH: Put
the switch to ON position, the indicator
shines for a moment. Put the switch to
MUTE, allows muting the microphone audio.
3. Low Battery LED indicator: This LED will glow continuously if the battery voltage is low thereby indicating
the need to replace the 9V battery by a new battery.
4. Battery Cover: Unscrew for access to the 9V battery and gain control.
1. Microphone Head (Lavalier)
2. Low Battery LED indicator: This LED will glow continuously
if the battery voltage is low thereby indicating the need to
replace the 9V batter by a new battery.
3. Power ON/OFF & Mute SWITCH: Put the switch to ON
position, the indicator shines for a moment.
Put the switch to MUTE, allows muting the microphone audio.
4. Input connector: Allows you to connect to the Lavalier.
5. Audio Gain Control: Provides audio level adjustment to
accommodate various input signal strengths.
- Make sure you can always see the receiver antenna from the transmitter position.
- Keep the distance from transmitter to receiver as short as possible
- Avoid placing the receiver antennas near metal surfaces and obstruction.
- Perform a walk through before performance or presentation. If dead spots are found,
adjust location of receiver. If dead spots remain mark spots and avoid.
