LED Program Board Help Messages
When the power is turned off, programs entered into the LED program board are
stored in memory utilizing a backup battery. The LED program board tests for a
low battery voltage when the COBE 2991 is turned on.
HELP 1
If the battery voltage is low, the HELP 1 message is displayed on the LED program
board (Figure 4-2). The COBE 2991 can be used after a HELP 1 message is
displayed. Press the STOP RESET button to clear the message from the LED
program board and proceed with normal operation. Contact a qualified service
representative to have the battery replaced.
