First, make sure that the receiver is not off. If there are many calls with the handset off, the replacement machine will be paralyzed.

In case of emergency, green and gray public telephones are relatively easier to connect than ordinary telephones.
In case of emergency, NTT East has prepared special public telephones at branch offices and sales offices in affected areas and evacuation area.

If you can tell your safety or check the safety of the other person, close the phone immediately. I'd like to talk briefly.
In addition, please obtain information on TV and radio mass media for damage situation.
