How do i factory reset my Harman Kardon avr 55 receiver

Troubleshooting Guide

Processor Reset
In the rare case where the unit's operation or
the displays seem abnormal, the cause may
involve the erratic operation of the system's
memory or microprocessor.
To correct this problem, first unplug the unit
from the AC wall outlet and wait at least three
minutes. After the pause, reconnect the AC
power cord and check the unit's operation. If
the system still malfunctions, a system reset
may clear the problem.
To clear the AVR 520's entire system memory
including tuner presets, output level settings delay times and speaker configuration data,
first put the unit in Standby by pressing the
System Power Control button 2. Next,
press and hold the Tone Mode 8 and the
FM Mode Selector ^ buttons for three
The unit will turn on automatically and display
the RESET message in the Main
Information Display Y. Note that once you
have cleared the memory in this manner, it is
necessary to reestablish all system configuration
settings and tuner presets.

My Haier dehumidifier has the bucket full light on and won't reset. It's only a month old. I tried unplugging, resetting and i'ts still stuck on bucket full. Any ideas on how

sorry to say but the bucket level sensors on these tend to be a bit tricky , it seems theres two possible holes the piviot point for float can go in , only one is correct for sensor to hit right , but both allow float to swing , and there not marked either

How can i save my settings on jvc kd-r446 ? every time i shut down my settings is reset

if it is resetting oon shut down , you dont have your memory wire connected to a full time power wire . full time power wire is a wire that has power even when car is off.. this is what saves your memory on the head unit.memory wire is usually yellow.

Garmin Nuvi 360 says memory full cant reset

Connect the unit up to a PC and try deleting some of the unused text-to- speech (TTS) voices. Keep only the ones that you need. Delete any unused photos or MP3's...and also any unused vehicle icons on the unit. When the unit is booting, it loads in all of the vehicle icons allowing you to change the selected vehicle, so this too uses up valuable memory.

I have added memory to my inspiron 2200 laptop...and the memory is reading 256mb before adding it was 526(something) is this going the wrong way?????also my computer seems slower....

First try reseating the memory. Sometimes memory dimms not fully seated will not register. If that doesnt work are you sure that you ordered/bought the correct memory for your unit. Some units require PARITY.. meaning that two different memory manufacturers may not be compatible in machine and you need two memory chips from same manufacturer and model and size.So if you have one from one company and one from the other the machine may be only recognizing one of them. If you have done both of the above.. Remove all memory and boot machine. Allow to do a full boot to OS and then shut down the unit via the OS... Start, Shutdown. Then reseat memory chips and reboot. Always do this with battery removed and on AC power.

Memory full is being displayed when i try to go to a new destination and when i try to delete a favourite the unit turns off.

Garmin nuvi 610 T
memory full was being displayed on screen whilst on destination ,sometimes followed by route waypoint memory full .

I found by turning unit off , then holding finger on top left of screen ,and at the same time turning back on again the unit would go into maintenance mode.
Follow prompts on screen to reset waypoint memory.
Mine works as good as gold now,hope this helps!

No power in any way

I charged it for about an hour on the bus connector (wall outlet did not appear to generate any charge). I then opened up the back and removed the battery. Put the battery back in; see if it starts. If so, turn off immiediately and continue to charge it to a full charge (at least 12 hours).

I found other users who experienced the same problem when their battery drained down to a very low level. The unit goes zombie and needs both a charge AND full reset (battery removal) before it can be resurrected.
