Troubleshooting with Error Codes (for Service Technicians)
The indicator lamp flashes to signal a specific problem area. Counting the number of short flashes after each long
flash will give the possible causes. Example: “— …. — ….” The LED gives a long flash for 0.6 seconds. Then it
gives 4 short flashes (indicated by the dots in the example). The sequence repeats unit the error is cancelled.
To obtain the internal data and error code for troubleshooting, you need an IR Adapter, proper connectors, and
software. The table below is a reference guide. For further information and assistance, please contact Garland
Technical Service.
