Two-way Voice Calls
If EXO has the two-way voice call feature enabled and is in cellular coverage, it can receive two-way voice calls from monitoring personnel as a response to high urgency notifications.
EXO automatically answers every voice call. You cannot initiate or end voice calls from EXO.
Monitoring personnel will initiate a voice call. If EXO is not already in a low urgency or high urgency state, it will inform you of the incoming call with a low urgency notification. You will then hear a chirp indicating the voice call has been connected.
Speak directly to EXO. The microphone is located to the left of the SOS latch (see EXO Pump Hardware Details or EXO Diffusion Hardware Details, depending on your model). If monitoring personnel are having a hard time clearly hearing your responses, you may need to move closer to EXO. When monitoring personnel have confirmed you are safe, they will end the call and you will hear another chirp indicating the voice call has been disconnected.
This feature is different from the push-to-talk (PTT) feature. Voice calls are not available when EXO uses the Iridium satellite network to connect to Blackline Live.
Volume
Two-way calls use EXO's speaker. The speaker's volume cannot be adjusted. See Speaker for more information about the speaker.
