Physical Connections
We will now discuss first the front panel and then the back panel connections.
Front Panel
(1) Power Switch
The FLEX-3000 uses a delayed start push-to-latch/push-to-release switch to power up the radio.
To turn on the radio, push the switch in fully to latch it in the on position. After a few seconds
you will hear the power relay click and see the blue LED illuminate to indicate that the radio is
powered up.
To turn off the radio, again push the button fully to unlatch it in the off position.
Note 1:
Make sure the FLEX-3000 is turned on and then wait 10-15 seconds
before starting PowerSDR. Otherwise, PowerSDR will indicate a
communication error and offer the option to run in Demo mode. Click
No
to close PowerSDR, turn on the FLEX-3000 and restart PowerSDR.
Note 2:
Make sure PowerSDR is shut-down before turning off the radio.
Otherwise, close PowerSDR and power cycle the FLEX-3000 (turn on,
off and on again) and restart PowerSDR.
