Probably not. Looked up documentation on this instrument. It's a TCAS/TAS and WX system, the screen we're looking at is the "Stby" mode. Use of the operating mode button will switch it from standby to operating.
You can and since the PT6 uses a starter generator it is impossible to use the generator while starting anyways. GPU is preferred to save the battery and reduce the risk of a hot start due to low Ng with a weak battery. Generator cross starts are usually done with multi engine aircraft.
