DRLC (Different Room Link Control) which lets you setup an optional remote control receiver in another room, and connect it to an input jack (that doesn't exist on my unit).
If the receiver is played at maximum volume, it will go into protect mode. Heat has something to do with it, as does the output capacitors. If both A and B speakers are turned on, the surround sound must be turned off. If protect mode occurs when operating with a DVD, the sampling frequency may be set too high (which probably isn't the issue with our stone-age DVD)
This problem also occurs on my STR-D790. The problem occurred for us in the winter, and the house was 69 degF. The unit is in an enclosure that gets warm, but not hot, and the configuration has been the same for a long time. We don't operate the unit at high volume, and only the A speakers were on.
I'm guessing that the problem is that the unit contains aluminum electrolytic output capacitors, and that they are drying out with age and losing their capacitance. The problem is intermittent now, but likely to get worse. These devices are known to have a limited lifespan.
I have not attempted to repair it yet, but if you wish to give it a shot try the following:
1) Unplug the unit (duh) and take your time getting it apart so the capacitors have a chance to discharge. Remove the internal circuit boards that have large cylindrical aluminum things with markings that include "uFd" (microfarads). If any of those have tops that look like they have ballooned out, they are shorted and definitely bad, but that isn't likely in this case.
2) Short across the terminals of each capacitor for a few seconds to discharge them. They are like little batteries. If it isn't there already, mark the circuit board with which side is the "+" terminal, based on the marking on the side of the capacitor.
3) Unsolder one or both leads, and measure the capacitor with that setting of a DMM if you have one available that does that. If it measures to its rated value, its probably okay...for now. If in doubt or you don't have the equipment to measure them, replace all the big ones.
4) Take the board to Radio Shack or an electronics parts store and get replacement parts. Newark Electronics or Digikey is good too. The voltage rating of the new part can be greater, the uFD rating can be a little greater, but it still has to fit in the location.
This is obviously pretty deep DIY.

What is fast rf?
Fast RF is a type of radio frequency transmission for sending data from a wireless input device (e.g. a cordless mouse) to a computer via attached receiver. Theoretically, Fast RF can be done at different transmission frequencies (i.e. the size of the radio wave, e.g. 2.4 gHz, etc.) but its main aspect is that it transmits data 125 times per second, much faster than wireless technologies prior to the creation of Fast RF standards. A standard USB port cannot read/understand more than 125 transmissions, so fast RF is as fast as it can handle (I presume USB 2.0 can go faster, as it's higher bandwidth, but don't know for sure). Short and sweet, if you want a wireless mouse and are using a USB 1 port or hub, Fast RF is as good as you'll see so far as speed is concerned, because it matches the maximum data rate of the USB port.
Where is the proper location for a main breaker in a panel?
Normally the main is on the top but you can install a service panel with the main on the bottom unless local codes prohibit it.
How do you decide on the rating of a main switch?
The rating of the main switch is decided upon by the current incoming mains. The main switch can't be lower than the incoming. In order to upgrade the main switch, the breaker box will need a complete upgrade.
The main advantage of ECL over TTL?
