Do the intercoms need pairing to work? If I add extra units to the existing system, do they need pairing?

No. They’re pre-configured at the factory—just plug in the power and use them right out of the box. Adding extra intercoms also does not require pairing. It's very user-friendly for first-time intercom users.

Why can only one side be heard while the other side can't hear?

Your environment is too noisy, causing interference. For two-way (hands-free) talk, use a relatively quiet place (e.g., a room, living room, or garage). If you need to use it on a noisy jobsite, press and hold “Talk” while speaking for communication

The call volume seems a bit low?

The other person is likely too far from the microphone. We recommend speaking about 30 cm (12 in) from the mic for better pickup and clearer sound.

Can the intercom use batteries?

No. The intercom has no battery compartment. However, we include a charging cable and adapter with each unit, so you can plug it in and use it right out of the box.

What is the Monitor function? How do I use it?

The monitor feature must be started from the device being monitored, so you can’t listen to someone proactively. This protects privacy. For example, unit 1 must press the Monitor button first, then select channel 2. Only then can 2 start monitoring 1
