5.2 Antenna Installation

Ensure the antenna on the bottom of the receiver is properly installed before use for optimal signal reception.

5.3 Power On/Off

Press and hold the Power Button on both the transmitter and receiver for a few seconds to turn them on or off.

5.4 Pairing the System (Infrared Automatic Pairing)

The system uses infrared automatic pairing for quick setup.

1. Turn on both the transmitter and receiver.
2. Ensure the transmitter and receiver are close to each other (within a few inches).
3. Press the IR Sync Button on both units. The units will automatically pair.
4. The RF indicator on the receiver will light up steadily once paired.

5.5 Channel Adjustment (for multiple systems)

The system offers 16 adjustable channels to prevent interference, supporting up to 4 systems simultaneously.

1. For the first system: Pair the transmitter and receiver as described in Section 5.4. Note the channel displayed on the receiver.
2. For subsequent systems: Before pairing, use the Frequency Plus/Minus buttons on the receiver to select a new channel. It is recommended to choose a channel number that is at least 3 channels apart from any already paired systems to minimize interference.
3. Once a new channel is selected on the receiver, press its IR Sync Button, then press the IR Sync Button on the corresponding transmitter to pair them.
4. Repeat this process for each additional system.

5.6 Connecting to Audio Systems

1. Plug the 6.35mm plug of the receiver into the instrument input of your active PA system, active speaker, amplifier, or audio mixer.
2. If your audio device requires a 3.5mm input, use the included 6.35mm to 3.5mm adapter.

5.7 Microphone Placement

Attach the transmitter's clip to the bell of your instrument (e.g., saxophone, trumpet, tuba). Adjust the flexible gooseneck to position the microphone for optimal sound capture.

• Ensure the microphone angle is approximately 45 degrees or greater relative to the instrument's bell.
• Maintain a distance of at least 10cm (approximately 4 inches) between the microphone and the instrument's sound source for best results.
• The rubber padding on the clip protects your instrument from damage.

6. Operation

6.1 Basic Usage

Once the transmitter and receiver are charged, paired, and connected to your audio system:

1. Turn on your audio system (PA, speaker, amplifier).
2. Adjust the volume on your audio system to a suitable level.
3. Begin playing your instrument. The sound will be transmitted wirelessly to your audio system.

7. Maintenance

7.1 Battery Care

• Recharge the units regularly, especially if they have not been used for an extended period.
• Avoid fully discharging the battery frequently to prolong its lifespan.
• Store the units in a cool, dry place when not in use.

7.2 Cleaning

• Wipe the exterior of the transmitter and receiver with a soft, dry cloth.
• Do not use harsh chemicals or abrasive cleaners.
• Keep the microphone head clean and free from dust or debris.

8. Troubleshooting

8.1 No Sound or Poor Sound Quality

• Check Power: Ensure both the transmitter and receiver are powered on and charged.
• Check Pairing: Verify that the transmitter and receiver are successfully paired (RF indicator on receiver should be steady). Re-pair if necessary.
• Check Connections: Ensure the receiver is securely plugged into your audio system's input.
• Adjust Volume: Increase the volume on your audio system and ensure the microphone is positioned correctly.
• Interference: If experiencing static or dropouts, try changing the channel on the receiver and re-pairing the units (refer to Section 5.5).
• Distance: Ensure the transmitter and receiver are within the effective operating range (up to 130ft/40m in open areas). Obstacles can reduce this range.
• Microphone Placement: Adjust the gooseneck to ensure the microphone is optimally positioned relative to the instrument (refer to Section 5.7).

8.2 Interference from Other Wireless Devices

• The ST-5 system operates on UHF frequencies. Other wireless devices operating on similar frequencies may cause interference.
• Change the operating channel of your ST-5 system (refer to Section 5.5) to find a clear frequency.
• Maintain a reasonable distance from other wireless equipment.

8.3 Short Battery Life

• Ensure the units are fully charged before use (2.5-3 hours).
• Battery performance may degrade over time with extensive use.
• Operating in extremely cold environments can temporarily reduce battery life.
