Front Panel
Operation After power is applied and the unit performs a self test, the idle display screen
appears as shown in Figure 3-2. The top display line is text that can be user
programmed (see User Info /Unit ID on page 42). The bottom line displays the unit
serial number and the hardware/ software revision numbers. The unit can be
accessed by pressing any front panel key.
Maintenance
Reset
The PRISM 3030 provides non-volatile memory retention of unit configuration in
the event of power failure. This feature allows the unit to automatically restore
normal service following a power loss. Note, however, that when the unit is stored
without power for an extended period, the battery drains and some parameters
might become corrupted.
Therefore, when the unit is first received for installation or if power has not been
applied for an extended period, a factory default maintenance reset operation
should be performed. This is done by pressing and holding the CLR button and
then applying power to the unit. Hold this key until the RAM CLEARED message
appears. This procedure installs the predefined ROM configuration to eliminate the
possibility of data corruption. The battery is fully charged after power has been
applied for 120 hours.
The maintenance reset operation sets all parameters to the factory default ROM
settings and zeros all performance registers.
Password If no password has been programmed, the password prompt does not appear and
the PRISM 3030 proceeds directly to the menu system. The unit is factory shipped
without a programmed password. The process of setting a password is described in
Edit Password on page 41.
If a password has been programmed, the password screen appears when any key is
pressed. Each character must be entered using the up and down arrow keys until
the desired character is displayed. Using the up arrow, the characters scroll 0
through 9, A through Z, and a through z for a total of 62 distinct characters. When
the correct character is displayed, press the right arrow to move the cursor to the
next position. The preceding character is accepted and disappears.
Continue this pattern until the last character is selected. Press the right arrow once
more and then press Select. If the password is correct, the unit advances into the
menu system. If the password is entered incorrectly, the idle display is returned
and another attempt can be made.
The password is case sensitive. Lower case and upper case characters must be
entered exactly as they were programmed.
