3. Replace the battery
Before replacing the battery, the setting information must be saved and the power supply switch in
the rear panel must be turned off. The DVR uses button battery. The system time must be checked
regularly. If the time is not correct you must replace the battery, we recommend replacing the battery
every year using the same battery type.
Note: The setting information must be saved before replacing the battery otherwise information
will be lost.
3-3 System Login
When the DVR boots up, the user must login and the system provides the corresponding
functions with the user preview. There are three user settings. The names are
admin
,
guest
and
default
and these names have no password. Admin is the super user preview; guest and default’s
permissions are preview and video playback. User admin and guest’s password can be revised,
while their permissions can’t be revised; user default is the default login user whose permission can
be revised but not its password.
