Interpret the LED Indicators at Startup
The C400, C600 and C1000 terminals have indicators on the back of the unit to isolate operating problems.
• Comm indicator for communications
• Fault indicator for hardware faults
At startup, the Fault indicator is off, except for a few brief flashes, and the Comm indicator is on. If the
indicators remain off, check the power cable. After a successful startup, both indicators are off and controlled
by the application running on the terminal.
The table shows the indicator states if the terminal stops during startup.
Battery Replacement
The C400, C600 and C1000 terminals contain a lithium battery that is intended to be replaced during the
life of the product. The battery provides battery backup for the real-time clock.
It is not used for application backup or retention.
