KMA-i800 Owner's Reference
Factory Restore
This will restore any internal settings back to their factory default values. Turn on the KMA-i800 from the rear panel. Wait
2 seconds after the green stand-by lights come on then press and hold the power button until the green lights begin to
fade out and in; release the power button. After about 13 seconds the lights will go off and then come back on steady. The
factory restore is done.
If the Web interface is inaccessible and the LAN connection is good, a factory restore may solve the problem.
Software Update
Note: Upon reaching a certain point in the update process power must not be removed from the KMA-i800. If this
happens, the unit may be rendered inoperable. Read through the entire software update process before attempting to
perform a software update.
From time to time Krell may release new versions of software to add features or fix a problem. The KMA-i800 must be
connected to the LAN router with access to the Internet in order to perform the software update. With the KMA-i800 in
stand-by press and hold the power button until the green stand-by lights begin to flash; release the power button.
While the green lights are flashing the unit is checking for newer software. If they stop flashing and stay steady that
means the unit already has the latest software. If the lights change to red that means it was unable to connect to the
server to check for software updates. This can be caused by a lack of connection to the LAN or the router not allowing the
KMA-i800 to connect to the Internet.
If there is new software available, the lights will start to flash blue. The KMA-i800 is downloading the software update. If
the lights change to red that means the download failed. Sometimes this can be caused by slow response over the
Internet. Try the software update again later.
When the unit is done downloading the software the lights will flash blue with two flashes per period. The unit is copying
and verifying the software download. If the lights change to red there was a problem with the downloaded file. Try the
software update again later.
Do not turn the unit off or otherwise remove power beyond this point in the software update process!
The lights will go off at this point and then come back on blue, fading in and out rapidly. The program memory is being
overwritten. The lights will then go off briefly and then come back on steady green. The KMA-i800 is in stand-by and is
ready to use.
