Garmin Master warning/caution selftest

Hello
I installed master warning/caution leds in my panel.
Before flight, I would like to test them to be working properly.
How can I self test them? is there such an option on the PFD?

Thanks
Oren

If the master is on and the engine is not running, you should get a low oil pressure and low volts alert, which should annunciate. Not sure which caution/warning alerts those will roll up to. But LEDs generally don't have a test anyway, as no bulbs to burn out.

That's my "hey, you left the master on" warning after shutdown in my old-school annunciator panel.
