Setup Instructions

Follow these steps to set up your Wuloo Wireless Intercom System.

1. Powering the Units

Connect the USB cable to the Power Port (DC 5V) on the back of each intercom unit.
Plug the other end of the USB cable into the provided power adapter.
Plug the power adapter into a standard electrical outlet. The unit will power on.

2. Setting Channels and Codes

For effective communication, all intercom units must be set to the same digital code and a unique channel for each user or location.

Diagram illustrating the three steps to set up an intercom system: 1st Step shows setting channel and code for each station, 2nd Step shows distributing different stations for different users (e.g., Code A Channel 3, Code A Channel 5, Code A Channel 6), and 3rd Step shows using multi-function communication.

Figure 4: Intercom System Setup Steps

Set Digital Code: On the back of each unit, select one of the three digital codes (A, B, or C) using the switch. All units intended to communicate with each other must use the same digital code.
Set Channel:
- To set your unit's channel: Long press the desired channel number key (0-9) until you hear a confirmation tone or see the display change.
- To call another intercom: Short press the channel key of the unit you wish to call. The system will automatically revert to its original channel after approximately one minute. You do not need to reset the code every time you call a different user.
Distribution: After setting a different channel for each user, distribute the intercoms. Ensure units are placed at least 16.5 feet (5 meters) apart to avoid interference during setup.

Recommendation: For optimal performance and to avoid interference, it is recommended to set all units to the same digital code and assign unique channels to each unit. This allows for direct calling between specific units.

Operating Instructions

Basic Communication (Talk)

To speak, press and hold the TALK button. Speak clearly into the microphone.
Release the TALK button to listen for a reply.
Important: There may be a slight delay (1-2 seconds) between pressing the TALK button and the transmission beginning. Wait briefly after pressing TALK before speaking to ensure the beginning of your message is not clipped.

Calling Another Unit

The receiving unit will emit a call alert (beep).
After the call alert, press the TALK button to initiate conversation.

Group Call

The monitored station will hear your voice.
To exit Monitor mode and resume normal communication, press the MONITOR button again.
Caution: While in Monitor mode, two-way communication is not possible.

VOX (Voice Operated Exchange) Mode

Press the VOX button to enable hands-free communication.
When VOX is active, the unit will automatically transmit when it detects sound above a certain threshold.
Another station can reply by pressing their TALK button.
Press the VOX button again to deactivate VOX mode.

Volume Adjustment

Maintenance

Proper care ensures the longevity of your intercom system.

Clean the units with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
Keep the units free from dust and debris.
Store the units in a cool, dry place when not in use for extended periods.
Ensure the antenna is not bent or damaged.

Troubleshooting

If you encounter issues, refer to the following common solutions:

Problem	Possible Cause	Solution
No power	Power adapter not connected or faulty outlet.	Ensure the power adapter is securely plugged into both the unit and a working electrical outlet. Try a different outlet.
Cannot communicate with another unit	Different digital code or channel settings; unit in Monitor mode; out of range.	Verify all units are set to the same digital code (A, B, or C). Ensure you are calling the correct channel number for the desired unit. Check if any unit is in Monitor mode and exit it if necessary. Reduce the distance between units.
Distorted or unclear audio	Interference; incorrect channel setting; low volume.	Try changing the channel number on all units to a different one (e.g., if on Channel 1, try Channel 2). Ensure units are not too close to each other (minimum 16.5 feet / 5 meters). Adjust the volume using VOL+ / VOL-. Avoid placing units near large metal objects or other electronic devices that may cause interference.
Beginning of message is cut off	Speaking too quickly after pressing TALK.	Press the TALK button and wait for approximately 1-2 seconds before speaking to allow the transmission to initiate fully.
