Mains power supply:
The 2 units can be operated with batteries as well as direct power to a power source.
1. Plug the power adapter included in the package into a power source
2. Turn on the unit and check that the power LED is on and green.
Low battery indicator and Out of range alert:
When the batteries are unloaded, the power LEDs of the two units become orange. In this situation, the batteries must
be replaced. If you intend to use the device for a long time, it is recommended to use the included power adapter.
If the receiver is too far from the transmitter, the two units will not work properly. You will hear an alert tone indicating
that you are outside the coverage area. At the same time, all volume LEDs will blink. In this situation, you will need to
position the two units closer together.
If the receiver is too close to the transmitter, you may hear an acoustic feedback. In this case, either move the two units
away or lower the volume.
If the receiver emits a background sound, it means the batteries are low and you have to replace them. Also, if the LED
lights are orange, the batteries will have to be replaced.
Troubleshooting:
Trouble
The presence of an upsetting background sound while
the unit is running on batteries.
The signal from the receiver is suddenly interrupted.
Weak signal

Solution
Check if the batteries are dischalowrged. Replace the
batteries if the LEDs become orange.
If the child unit does not perceive any sound, it will cease
to emit to the parent unit. The parent unit is in VOX mode
(stand by mode). When the transmitter sounds again,
it sends a signal to the receiver unit, putting it back on
again.
Ensure that the two units are not out of range. In extreme
cases, you can try changing the channel, pairing again
the two units.
