Description
Indicates the SC720/SC820 receiver is detecting radio carrier activity (Carrier
Detect - CD), on the RF channel, when the BUSY LED illuminates GREEN. This
is an indication that the SC720/SC820 is receiving some type of radio carrier
activity, NOT necessarily a SAFECOM transmission.
Microphone - Input receptacle for connecting an external microphone.
The MIC receptacle is NOT used for the data repeater communications. The
SC720/SC820 will NOT pass or transmit voice audio.
However, a microphone may be used as a TEST button to transmit a test data
pattern, high speed alternating tones, when the SC720/SC820 is NOT in the
repeat mode. The test data pattern may be used as a quick check to verify the
following:
•
Modulation Deviation
•
Transmitter Output Frequency
•
Transmitter Output Power
•
Antenna System SWR
•
Functionality of the DK1000 Controller Board
See section 4.3.1 Transmit a Test Data Pattern for the procedure on how to
transmit a Test Data Pattern.
Monitor - The MONI button is NOT used for the data repeater communications.
The position of the MONI button does NOT affect SC720/SC820 Data Repeater
communications.
However, the Monitor function can be used to select audible monitoring, heard
from the internally mounted speaker, of SAFECOM ONLY (see section 4.3.2
Audibly Monitor Only SAFECOM Messages) radio messages or ALL
radio activity on the RF channel (see section 4.3.3
Activity).
