Before first use, fully charge the AH9 headset transmitter. Connect the supplied USB charging cable to the AH9 and a USB power source (e.g., a computer USB port or a USB wall adapter). The charging indicator on the AH9 will illuminate during charging and turn off when fully charged. Charging typically takes approximately 3 hours.
5.2 Posicionamento e conexões do receptor
- Colocação: Position the AR99m receiver in a location free from obstructions, ideally within line-of-sight of the intended operating area. Ensure the antennas are extended and positioned vertically for optimal reception.
- Poder: Connect the supplied 15V DC power adapter to the AR99m receiver's 'DC IN' port and plug it into an AC power outlet.
- Saída de áudio: Connect the AR99m receiver's audio output to your mixer, amplifier, or powered speaker. Use either the balanced XLR output for long cable runs and professional connections, or the unbalanced 1/4" output for standard instrument inputs.
5.3 Utilizando o fone de ouvido
Place the AH9 headset comfortably on your head. Adjust the microphone boom so that the DE10x microphone is positioned approximately 1-2 inches from the corner of your mouth. Ensure the headset is secure but not uncomfortably tight.

6.2 Channel Selection and Synchronization
The Airline 99M system operates on 100 selectable channels across a 24MHz bandwidth (D Band: 542–566 MHz). To ensure optimal performance and avoid interference, synchronize the transmitter and receiver to the same channel.

- Synchronize Transmitter: Once a channel is selected on the receiver, hold the AH9 transmitter near the AR99m receiver (within 1-2 feet). Press and hold the 'SET' button on the AR99m receiver until the 'IR' indicator flashes. The AH9 transmitter will automatically synchronize to the selected channel. The 'READY' indicator on the receiver will illuminate solid when synchronization is successful.
6.3 Ajuste de volume

- AR99m Receiver: Use the 'VOLUME' knob on the AR99m receiver to adjust the overall output level to your connected audio system.
Always adjust the volume on your connected mixer or amplifier first, then fine-tune with the receiver's volume control.
6.4 Faixa de Operação
The system offers a working range of up to 300 feet (line-of-sight). Environmental factors, such as walls, metal objects, and other wireless devices, can affect this range. Maintain a clear path between the transmitter and receiver for best results.
