Fallback
Your phone has a fallback function. When there are some troubles
on PTT system, the phone will activate fallback mode.
When the signal icon turns to the twinkling fallback icon, it means
that the phone is in the fallback mode.
In fallback mode, the phone can only execute parts of PTT functions.
The Group Calls such as the Normal Group Call and Emergency
Group Call, Broadcast Call and Pre-emptive Group Call can work
well, but some functions may not work.
