function of Windows or anti-virus
software.
In this case, the communication
transmitted from G-50 may not partially be
received. Please remove the check mark
on the Firewall function of the necessary
port. (For detail, please refer to Page 57.)
(If the version of G-50 is more than 2.50,
only [IC] can be searched, even if it uses
FIREWALL. However, [OC] reference
cannot be performed. Moreover, since
other functions cannot operate normally,
please be sure to remove a check.)
When a maintenance tool is not ended
normally, G-50 will be in a data resending
state, and LAN communication will

In this case, please perform "Stop mail
communication" of 3.4 (2), and start a
maintenance tool again after waiting
about 15 minutes.
The version of G-50 is old.
