This is a great fighter - lightweight, good short field performance, versatile, inexpensive, excellent flight performance and good avionics.
If I could see the HUD symbology, I could make a better guess, but I heard four distinct "beeping" tones...each one an alert. The fast-paced beeping was clearly an AOA warning. Lower speed beeping was a GPWS (ground alerting system). A couple of other beeping alerts were present, and I suspect they were different GPWS modes (bank angle, rate of descent, etc.). I can't tell exactly...
The Swedish AF has long had dispersed basees (highway sections) and LOTS of airplanes per capita - to counter the Russian threat. This airplane is a great fighter for their needs: the short field performance allows for the use of those dispersed bases. It's not long range, but it doesn't need to be. It's fast. It's simple to maintain (single engine). It's got excellent handling and flight performance.
This video was about the Gripen "E" model - a significant upgrade to the original plane. It's got a GE F414 in place of the GE F404 (yeah, it's called a Volvo, but it's a license-built engine), which adds a lot of thrust. It's got more fuel, longer range, increased hardpoints, and, most important, a new AESA radar. The AESA (electronically scanned, AKA phased array) is state of the art. The Russians have one, we have a couple, and there is this one. AESA allows you to reprogram the radar, and change its performance, all via software, to meet evolving threats and support new missiles/weapons. AESA radars can be used to gather ELINT (electronic snooping) and, in many cases, perform electronic warfare (jamming, deception, and degradation and attack of enemy radars and systems). The radar is indigenous. Swedish built.
I've suggested that other nations should be considering this airplane in previous BITOG threads. I stand by that recommendation. This is an excellent fighter.
