11 INSTRUCTIONS FOR CONTINUED AIRWORTHINESS
The instructions contained in this section are for general reference. The FAA AEG accepted
Instructions for Continued Airworthiness are contained in the STC data package (reference
Sandel document 82046-STC27-05).
Normal maintenance activities performed on the ST3400H should follow standard industry
practices. Re-programming the Configuration Module and updating the Databases, are
addressed in specific sections of this installation manual.
11.1 Periodic Maintenance
The ST3400H is designed to detect internal failures. A thorough self-test is executed
automatically upon application of power to the unit, and Built-In-Test (BIT) is continuously
executed. Detected errors are indicated on the equipment via failure messages and
maintenance is on-condition. Operation of the ST3400H is not permitted unless an inspection
as described in this section has been completed within the preceding 12 calendar months.
Conduct a visual inspection on the ST3400H and its wire harness to insure installation
integrity:
•
Inspect the unit for security of attachment.
•
Inspect buttons for legibility.
•
Inspect condition of wiring, routing and attachment/clamping.
•
Inspect knob operation.
•
Inspect front panel and clean as necessary
11.2 Cleaning the Front Panel
The front bezel, keypad, and display can be cleaned with a soft cotton cloth dampened with
“Edmund Scientific TECH SPEC Lens Cleaner” or equivalent. Care should be taken to avoid
scratching the surface of the display.
11.3 Display Light Source
The display light source is rated by the manufacturer as having a usable life of 80,000 hours.
This life may be more or less than the rated time depending on the operating conditions of the
ST3400H. Over time, the light source may dim and the display may not perform as well in
direct sunlight conditions. The user must determine by observation when the display
brightness is not suitable for its intended use. Contact the Sandel Customer Service if the light
source requires service.
11.4 Trouble Shooting Information
If the ST3400H fails to properly operate, consult a local authorized Sandel dealer for repair.
The ST3400H does not contain any user serviceable components.
