Tip: You can use a fully qualified domain name instead of an IP
address for most configuration options calling for an IP address if your
PinPoint-E is configured to use DNS. Refer to the IP Manager chapter
for how to configure DNS and how to allow your PinPoint-E use a
domain name even with a dynamic IP address account from Verizon.

Tip: AceManager displays the current time (UTC) set in the PinPoint-
E and does not translate it to the local time zone. If the PinPoint-E is
in California and it is 8 a.m., the modem’s time will be shown as 4 p.m,
since UTC is 8 hours “ahead” of Pacific time (UTC-8).
