• Communication is not possible even inside
the service area in places where the signal
does not reach (e.g. tunnels and basements).
Also, communication may not be possible in
poor reception areas. Communication may be
interrupted if you move into poor reception areas
during communications.
• Since this product uses radio waves, the
possibility of communication intercepts by third
parties cannot be eliminated (though the LTE/
WiMAX 2+/GSM/UMTS system has highly secure
confidential communication features).
• VoLTE (LTE network) by au is used when
connecting with emergency call receiving
agencies within Japan. You cannot connect using
3G (circuit-switched network).
• The product is compatible with au World Service.
Each network service described in this manual
varies depending on the area and service content.
• Since the product is a radio station under the
Radio Law, you may be asked to temporarily
submit the product for inspection in accordance
with the Radio Law.
