Entering the Setup Mode
Setup of the C-6200 is almost entirely done using a web browser. The first step required during setup
is to assign the Ethernet and Mask addresses to the C-6200. This is done through the front panel. To
enter the front panel setup mode, press and hold MUTE-F16-GRP.
Setting the System Clock
Pressing PROG1 from the top-level setup menu will open the screen to set the internal Real Time
Clock. PROG1 selects the Edit option that allows setting of the actual minutes and hours. PROG2
sets AM or PM., PROG3 selects 12 or 24-hour mode, PROG4 returns to the previous setup screen.
The clock can also be directly setup by pressing MUTE-F16-C1. This key sequence bypasses the
PIN number and the main setup screen.
Setting the PIN number
The Pin number is used to prevent unauthorized modification of operation parameters. When a PIN
number is set, the C-6200 will prompt for it before allowing entry into the setup mode. The web-
based setup for the C-6200 also has provision for a user password; it is the same four-digit value as
the PIN number entered from this menu option. Selecting PROG3 from the main menu will cause
the C-6200 to prompt for the new PIN number twice. If both are entered identically, the new PIN
number will take affect.
