This is from the V-1 web site for the serial#:
Status Report on Your Valentine One
Serial Number 4579240529
V1 Description: Radar circuitry known in-house as V1.7 gives high performance on all radar bands. Also,it remembers your “mode” setting when shut off. Has stack of four LEDs on front panel for band identification. Front and rear laser.
Upgrade Recommendation: While this version is not quite up to today’s V1 standard for Ka, it’s almost always good enough, and always better than detectors from other makers. X and K performance is excellent. Upgrading merely to improve radar performance is not cost effective, in my opinion, unless you’re concerned about the POP Mode operating in your area. Upgrading does bring other benefits, including our latest laser warning (front and rear), which outperforms the competitors by a wide margin, and POP Protection. Also, you'll get the new Euro Mode.
