Changing Videophone Call to Voice Call
The caller can change the videophone call to a voice call during a videophone call (communication
speed 64K).
d
If the handset of your party is a FOMA terminal supporting the call change, “Change to voice” can be
selected from the function menu during a videophone call and you can switch between videophone and
voice calls. (This function is available between terminals that support change between voice call and
videophone call.)
d
You can change a videophone call only when you are the caller. When you are a callee, you cannot
change the call mode.
d
To change the call mode, the other party must set his or her terminal to show you “Indicate V.phone”
beforehand.

voltage alarm was given.
