Power-Up SRPT-30/40A
If using AC line, turn on SRPT-30/40A by turning on front panel AC LINE switch. If using 12-15 Volt or 15-30
Volt external DC supply, turn on SRPT-30/40A by turning on external DC supply. Refer to the External DC Supply
Operation procedure above for proper installation and operation.
The SRPT-30/40A will begin a power-up routine. The front panel meter will illuminate immediately. After about
three seconds the AFC LOCK LED will begin flashing green indicating that the synthesizer is searching for the last
frequency it was last locked on to.
If the TRANSMIT/STANDBY switch is in the TRANSMIT position, the TRANSMIT LED will flash red in unison
with the green flashing AFC LOCK LED. Once the synthesizer has found and locked onto the frequency, the AFC
LOCK LED will immediately stay on solid green and the TRANSMIT LED will continue to flash red for three
additional seconds. After the three seconds, the SYNTHESIZER will be ready, will enable the power amplifier to
transmit RF power, and the TRANSMIT LED will stay on solid red.
