Setting Password
A password can be used for protecting CSE-M53G from TELNET login or changing
environmental parameters by hosts which are not qualified. The maximum length is 8
bytes of Alphabet or number.
When you want to revoke all of these restrictions, operate CSE-M53G as ISP mode.
In the mode, all restrictions are removable and communication with ezManager is
revoked.
