Power/Mute Switch: Controls power and mutes the microphone output.
Status LED: Indicates power, battery status, and mute status.
Battery Compartment: Houses two AA batteries.

Setup

1. Receiver Placement

Place the SR100 receiver in a location where it has a clear line of sight to the area where the microphone will be used. Avoid placing it near large metal objects, Wi-Fi routers, or other 2.4 GHz devices that could cause interference.

2. Powering the Receiver

Connect the universal AC power adapter to the DC input on the rear of the SR100 receiver.
Plug the power adapter into a suitable electrical outlet.
Press the power button on the front of the receiver to turn it on. The status indicator will illuminate.

3. Connecting the Receiver to an Audio System

Use an XLR cable (not included) to connect the XLR output on the rear of the SR100 receiver to an input on your mixer, PA system, or audio interface.

4. Installing Batteries in the Microphone

Unscrew the bottom part of the HT100 microphone to reveal the battery compartment.
Insert two AA batteries, ensuring correct polarity (+/-).
Screw the bottom part back onto the microphone securely.

5. Pairing the Microphone and Receiver

The DMS100 system is designed for seamless setup. The microphone and receiver should automatically pair upon power-up if they are within range and on the same channel. If pairing does not occur automatically:

Ensure both the receiver and microphone are powered on.
Check the status indicators on both devices. The receiver's signal indicator should show a stable connection.
If issues persist, refer to the Troubleshooting section or consult the full manual for manual pairing instructions if applicable (though typically not needed for DMS100).

Operating Instructions

Turning On/Off

Receiver: Press the power button on the front panel.
Microphone: Slide the power/mute switch on the HT100 microphone to the "POWER" position.

Muting the Microphone

To temporarily silence the microphone output without turning it off, slide the power/mute switch on the HT100 microphone to the "MUTE" position. The status LED on the microphone will change to indicate mute status.

Adjusting Volume

Adjust the output volume of the receiver using the volume knob on the front panel of the SR100. It is recommended to start with a lower volume and gradually increase it to avoid sudden loud sounds.

Battery Life

The HT100 microphone provides extended battery life. The status LED on the microphone will indicate low battery status, typically by changing color or flashing. Replace batteries promptly when indicated to ensure uninterrupted performance.

Maintenance

Cleaning: Use a soft, dry cloth to clean the surfaces of the receiver and microphone. Do not use liquid cleaners or solvents.
Storage: When not in use, store the system in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries from the microphone if storing for an extended period.
Microphone Grille: Periodically check the microphone grille for debris. Clean gently with a soft brush if necessary.

Troubleshooting

Problem	Possible Cause	Solution
No sound from microphone	Microphone or receiver not powered on. Microphone muted. Low or dead batteries in microphone. Receiver not connected to audio system. Volume on receiver or mixer too low. Microphone and receiver not paired.	Ensure both devices are powered on. Check mute switch on microphone. Replace batteries in microphone. Verify XLR cable connection to audio system. Increase volume on receiver and mixer. Power cycle both devices to re-establish pairing.
Interference or dropouts	Too far from receiver. Obstructions between microphone and receiver. Interference from other 2.4 GHz devices (Wi-Fi, Bluetooth). Multiple DMS100 systems too close.	Reduce distance between microphone and receiver (max 30 meters/100 feet). Ensure clear line of sight. Move receiver away from other wireless devices. Ensure proper channel management if using multiple systems (DMS100 supports up to four simultaneous systems).
Poor audio quality	Low battery. Microphone too far from sound source. Input gain on mixer/PA system incorrect.	Replace batteries. Hold microphone closer to the speaker/singer. Adjust input gain on your audio system.
