6. GDMS/TR-069 function
When the device opens TR-069 or Grandstream’s GDMS function, it will cause the device to establish
connection regularly and report relevant status to the server. Please turn off TR069 function or adjust the
“Periodic Inform Interval” of TR069 to a longer duration.

7. The device has no access to the Internet
When the device cannot access the Internet, it may keep attempting DNS resolution which may lead to
faster power loss. If the device is not setup to send outbound traffic, please set it to use an internal DNS
server.
8. Long storage without charging
When the battery power reaches 0%, it will be completely discharged. Prolonged storage in this state will
damage the battery and lead to poor battery performance over time. Please check the battery level regularly
and maintain the battery so it does not become completely discharged.
