Panel lock on dra 397

This may not work, as it appears to be for a different model, but it states:

How do I unlock the panel on my DRA-397?

Power the unit off using the On/Off button. (not the larger On/Standby button) While the unit is powered off, press and hold the "Speaker B" and "Mode" buttons. Without releasing those buttons, power the unit back on. This will unlock the panel.

Let's understand this - you have an external volume control wired in series with each front speaker set?

Can you elaborate on their electrical characteristics?

A + B 8 - 16 ohms

Check for a reset of the receiver. If no mention in manual you might want to check with the manufacturer for a code . If nada then the electronics are fubar and you are SOL.

Hold the "Speaker B" button and the "Mode" buttons. Turn power on.

Hello,

Denon has for some reason removed this function from their user manuals. However The manual does show how to do a manual reset of the unit. This may correct the issue.

With the Amp OFF but plugged in, press and hold the speaker A and B buttons and while still holding them press the POWER button. Continue to hold the speaker buttons for another second or so. The display should all light up and flash at 1-second intervals. If not flashing, try again.

This should reset the unit back to factory state with the front panel lock disabled.

make sure unit is off then hold down spker b and mode buttons and then turn it on

Hi, Press the B and the Mode buttons and then hit the power button.  This should unlock the panel....it worked for me.

This worked for me, but I'm sure tired of constantly searching for ways to fix the problems I encounter with my Denon DRA-397. When it works, it's great, but I don't have a degree in electrical engineering. Why can't they produce a user friendly trouble shooting guide?

press mode and speaker b while turning the receiver on. the reset the processor..
