For 2 plus years our 622 has been flawless. This morning our power went off for about 10 seconds. Now this has happened many times over the past 2 years. Every time the 622 has kicked back on and worked perfectly. This time. 622 went into it's reboot mode. And that's where it's stuck. Transponder #s are changing but nothing else. We do have access to recorded material. I tried another soft reset and still the same. Suggestions. Hammer and duct tape???
