To set up the monitor, plug the base unit into a power outlet and turn it on. Place the receiver unit in the desired location and ensure both units are set to the same channel. Adjust the volume on the receiver to your preference.
Try changing the channel on both the base and receiver units to avoid interference. Ensure there are no large metal objects or electronic devices between the units that could obstruct the signal.
To extend battery life, turn off the receiver when not in use and ensure it is fully charged before use. You can also reduce the volume or use the power-saving mode if available.
The high-pitched noise may be due to feedback. Ensure the base and receiver units are not too close together and adjust the volume settings. Changing the channel may also help reduce feedback.
Check if the receiver's battery is charged. If not, connect it to a power source using the provided adapter. If it still does not turn on, inspect the adapter and charging port for any damage.
To clean the units, use a soft, dry cloth to wipe the surfaces. Avoid using water or cleaning agents. Regularly check the units for dust and debris, especially around the speaker and microphone areas.
Yes, you can use multiple receiver units with one base unit. Ensure all receivers are set to the same channel as the base unit for proper communication.
The monitor has an effective range of up to 900 feet under optimal conditions. However, walls, furniture, and other obstacles can reduce its range.
Check if the microphone on the base unit is unobstructed and ensure the volume on the receiver is turned up. Verify that both units are on the same channel and that the base unit is positioned near the sound source.
