Introduction
The BYHUBYENG FLYDOG Signal Repeater, Model 160A, is designed to extend the range and amplify the signal of compatible BYHUBYENG call bell systems. This device ensures reliable communication by strengthening signals in environments where obstacles or distance might otherwise cause interference or signal loss. It is compatible with BYHUBYENG call buttons and receivers such as models 200E, 200VT, 200D, 300S-Q, and 400D-JPU.
Important Note: This signal repeater cannot function as a standalone device. It must be used in conjunction with other compatible BYHUBYENG call system components.

Setup
The BYHUBYENG FLYDOG Signal Repeater is designed for ease of use with minimal setup required. It is ready to operate immediately upon connection to a power source.
Installation Steps:
- Unpack the Repeater: Carefully remove the signal repeater and its power adapter from the packaging.
- Connect Power: Plug the DC 5V power adapter into the repeater's DC 5V port. Then, plug the adapter into a standard electrical outlet.
- Positioning: Place the repeater in a central location between your BYHUBYENG call buttons/transmitters and receivers to maximize signal coverage. Ensure the retractable antennas (ANT1 and ANT2) are extended for optimal performance. Avoid placing the repeater near large metal objects or other sources of electromagnetic interference.
- Compatibility Check: Ensure that your existing BYHUBYENG call system components (e.g., call buttons 200E, 200VT, 200D, 300S-Q, 400D-JPU) are compatible with this repeater. The repeater will automatically extend the signal for these devices.

Operating Instructions
The signal repeater operates automatically to extend the range of your BYHUBYENG call system. No manual configuration is typically needed for basic signal amplification.
Basic Operation:
- Once powered on, the repeater will automatically detect and amplify signals from compatible BYHUBYENG call buttons.
- The amplified signal is then transmitted to compatible BYHUBYENG receivers (e.g., wristwatches, display panels).
- The LED display screen on the repeater may show status indicators or numerical values depending on the operational mode.
Key Functions (K1 & K2):
The repeater features two keys, K1 and K2, for advanced settings or adjustments:
- K1 Key:
- Long Press: Confirm or save settings.
- Short Press: Adjust numerical values.
- K2 Key:
- Long Press: Enter or exit setting mode.
- Short Press: Select position or option.
Refer to the detailed Japanese instruction manual included in the package for specific advanced configuration procedures.

This diagram illustrates the signal flow: a user presses a call button (transmitter), the signal is sent to the repeater, which then amplifies and re-transmits it to the receiver (e.g., display panel or wrist receiver), indicating the service request.

This image displays various compatible BYHUBYENG call system components, including different models of wrist receivers (CS-200E), display panels (CS-200D, CS-300S-Q, CS-300L, CS-400D), and call buttons (M1, O1, X1, S1, S3, O3, E6, G3, G6). It emphasizes the repeater's ability to handle one-to-many, many-to-one, and many-to-many signal extensions.
Maintenance
To ensure the longevity and optimal performance of your BYHUBYENG FLYDOG Signal Repeater, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the exterior of the repeater. Do not use liquid cleaners, aerosols, or solvents, as these can damage the device.
- Environment: Keep the repeater in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.
- Antennas: Handle the retractable antennas with care to prevent bending or breaking. Ensure they are fully extended during operation for best signal reception and transmission.
- Power Supply: Only use the original power adapter provided with the device. Using an incompatible power supply may damage the repeater or pose a safety risk.
Troubleshooting
If you encounter issues with your BYHUBYENG FLYDOG Signal Repeater, please refer to the following common troubleshooting steps:
- No Power:
- Ensure the power adapter is securely plugged into both the repeater and a working electrical outlet.
- Check if the power outlet is functional by plugging in another device.
- Poor Signal Extension:
- Verify that the repeater is positioned centrally between the call buttons/transmitters and receivers.
- Ensure the retractable antennas are fully extended and unobstructed.
- Relocate the repeater to avoid potential signal interference from thick walls, metal objects, or other electronic devices.
- Confirm that all BYHUBYENG call system components are compatible with the Model 160A repeater.
- Device Not Responding:
- If the repeater's LED display is off or unresponsive, try power cycling the device (unplug and re-plug the power adapter).
- If issues persist, consult the detailed Japanese instruction manual for advanced troubleshooting or contact customer support.
