70-STR1700-000 Rev A.1 STR-1700 O&M Manual SECTION 3 OPERATION Operation of the STR-1700 is accomplished by utilizing a special software program to configure the radio for the proper configuration and then connecting the system into the target platform for audio data transmission and reception. The following sections describe the STR-1700 operations from the perspective of configuring the unit for the proper radio channel characteristics prior to final system installation. 3.
70-STR1700-000 Rev A.1 STR-1700 O&M Manual 3.4 Getting Started 3.4.1 Radio Interconnect Before taking any actions from the control program with an STR-1700 radio, the radio must be connected to a primary power source and to the PC via a special programming interface cable and adapter. The following figure depicts the required interconnects. Programming Interface Adaptor 13.
70-STR1700-000 Rev A.1 STR-1700 O&M Manual radio has been inadvertently left in an “OFF” condition, this will toggle the state, which should then illuminate the LED. If this action fails to correct the problem, the user should validate the primary power connection to the radio and then attempt the “ON”/”OFF” toggle switch again. 3.4.3 Reading the Radio Configuration Assuming the above process is successful, the user can proceed to activate the STR1700.exe program.
70-STR1700-000 Rev A.1 STR-1700 O&M Manual 3.5 Altering the Radio Configuration 3.5.1 Changing Individual Channel Settings Once a radio has been read as described above, the channel configuration fields on the right hand side of the screen may be edited. The frequency field may be changed via standard text edit methods, or it may be incremented or decremented via the arrows located at the side of each setting.

At the same time, the display will be updated to reflect the new information for the radio. 3.5.3 Saving/Restoring Channel Parameters In addition to saving default settings for each model type, the control software also supports saving and restoring channel parameters pertaining to frequency, bandwidth, and output power levels to user specified disk files.
70-STR1700-000 Rev A.1 STR-1700 O&M Manual SECTION 4 MAINTENANCE In order to ensure that the STR-1700 system is always ready for operation, it should be checked periodically so that potential defects may be discovered and corrected before they develop into any serious damage or system failure. A minimal preventive maintenance program will significantly increase the systems life span.
70-STR1700-000 Rev A.1 4.2.2 STR-1700 O&M Manual Cleaning Clean the outside surfaces and areas around the connectors periodically. Clean the surfaces with a clean, soft, lint-free cloth. Clean the areas around the connectors with a soft bristle brush. To remove grease, fungus, or corrosion, use a cloth dampened with an appropriate electronics cleaning fluid. Cleaning should be done at least once every month.
