6.2 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 red alerts.
Two-way voice calls only work when EXO is connected to the Blackline
Safety Cloud through a cellular network. G7 EXO automatically answers
every voice call. You cannot initiate or end voice calls from EXO.
How does a two-way voice call work?
Monitoring personnel will initiate the call. If EXO is not already in an alert
state, it will inform you of the incoming call with a yellow warning alarm.
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 section 1.7). If monitoring personnel are having a hard time
clearly hearing your responses, you may need to move closer to EXO.
When monitoring personnel have conrmed you are safe, they will end
the call and you will hear another chirp indicating the voice call has
been disconnected.
NOTE: This feature is dierent from the push-to-talk (PTT) feature. Voice
calls are not available when EXO is connected to the Blackline Safety Cloud
through the Iridium satellite network.
Volume
Two-way calls use EXO’s speaker. The speaker’s volume is set at 85 dB
and cannot be adjusted. See section 3.7 for more information about
the speaker.
