4. Setup Guide

4.1 Power Connection

1. Connect the provided USB power cable to the DC IN (Type-C) port on the transmitter.
2. Plug the other end of the USB cable into a 5V USB power adapter (not included) or a USB port on your TV/PC.

4.2 Audio Input Connection

The BT5804 supports Auxiliary (3.5mm), RCA, and Optical audio inputs. The device automatically recognizes the connected cable.

Figure 3: Flexible Audio Connections. This image highlights the various input ports available on the back of the transmitter: DC IN (Type-C), AUX, and OPTICAL.

• For Optical Connection: Connect one end of the optical cable to the OPTICAL port on the transmitter and the other end to the optical audio output port on your TV or other audio source. Ensure your TV's audio output is set to PCM/Stereo format.
• For AUX (3.5mm) Connection: Connect one end of the 3.5mm audio cable to the AUX port on the transmitter and the other end to the 3.5mm audio output (headphone jack) on your device.
• For RCA Connection: Use the provided RCA to 3.5mm cable. Connect the RCA ends to the red and white audio output ports on your device, and the 3.5mm end to the AUX port on the transmitter.

4.3 Initial Pairing

1. Power on the ZIOCOM BT5804 transmitter. It will automatically enter pairing mode, indicated by a flashing Bluetooth icon on its display.
2. Put your Bluetooth headphones or speaker into pairing mode (refer to your device's manual for specific instructions).
3. Place the headphones/speaker close to the transmitter. The transmitter will automatically search for and connect to nearby Bluetooth devices.
4. Once connected, the Bluetooth icon on the transmitter's display will become solid, and the name of the connected device may appear.

5. Operating Instructions

5.1 Power On/Off

• To power on, connect the device to a 5V power source. It will automatically turn on.
• To power off, disconnect the power cable.

5.2 Connecting Two Headphones Simultaneously

The BT5804 can transmit audio to two Bluetooth headphones at the same time.

1. First, connect one pair of Bluetooth headphones as described in Section 4.3.
2. Once the first pair is connected, put the second pair of Bluetooth headphones into pairing mode.
3. The transmitter will automatically search for and connect to the second device.
4. Both headphones will now receive audio from the transmitter.

5.3 Reconnecting

After initial pairing, the transmitter will automatically attempt to reconnect to the last paired devices when powered on.

6. Maintenance

To ensure the longevity and optimal performance of your ZIOCOM BT5804 Bluetooth Transmitter, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the device. Avoid using liquid cleaners or solvents, as they may damage the surface or internal components.
• Storage: Store the device in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
• Handling: Handle the device with care. Avoid dropping it or subjecting it to strong impacts.
• Environment: Do not expose the device to water or other liquids. Keep it away from heat sources and open flames.

7. Troubleshooting

If you encounter issues with your ZIOCOM BT5804, please refer to the following common problems and solutions:

• No Audio After Successful Pairing:
          If connecting via optical cable, ensure your TV's audio output format is set to PCM/Stereo. Different TVs may have varying settings for this. Check your TV's audio settings menu.
• Audio Delay/Lag (Even with aptX Low Latency):
          For aptX Low Latency (aptX-LL) to function correctly and eliminate audio delays, both the ZIOCOM BT5804 transmitter and your Bluetooth headphones/speaker must support aptX-LL. If your receiving device does not support aptX-LL, you may still experience some audio-video synchronization delay.
• Connection Issues or Short Range:
          The 30-meter range is an optimal value. Physical obstructions (walls, furniture) and wireless interference (Wi-Fi routers, other Bluetooth devices) can reduce the effective transmission distance. Try moving the transmitter and receiving device closer or away from potential interference sources.
• Device Not Powering On:
          Ensure the USB power cable is securely connected to both the transmitter and a functional 5V USB power source. The product does not include a power adapter; use a standard 5V USB adapter.
