(1).
If you need to stay in intercom connection for a long period of time, it
is suggested that you set both your headset and your target headset to
Level 5 (i.e., Manual Activation Mode). In manual activation mode, the
function to automatically end an intercom connection when detecting
10-second silence will be disabled. In manual activation mode, you must
manually terminate an intercom connection.
(2).
During an intercom connection, any incoming call (cell phone) to one
of the two headsets will automatically end the intercom connection. The
headset without the incoming call will resume the state prior to the
intercom connection, until the headset with the incoming call terminate or
reject the call, and then the intercom connection resumes.
Use Your GPS
If you have paired your OpenRoad headset with GPS, you could hear the
voice instruction from the GPS through the headset. If you are on an intercom
with another headset when the GPS voice instruction comes in, you can hear
<dodo> through your OpenRoad headset to indicate the incoming GPS
instructions. If you want to listen to the voice instruction from GPS, you can
press [MFB] to end the intercom and the GPS voice instruction will
immediately pass to your OpenRoad headset.
During the GPS voice instruction, you cannot activate the intercom. You
must wait until the GPS voice instruction is over before you can activate the
intercom.
