Firmware Update for the DTR-70.1/80.1 and DHC-80.1
We are pleased to offer this firmware update for the best possible performance of your AV
Receiver.
The firmware update may fail if an external HDMI control signal is input during the update
procedure. Please be sure to turn off the HDMI control function (RIHD) on your A/V receiver
before starting the update.
How to turn off RIHD:
In the Main menu select "7. Hardware Setup", then "7-4. HDMI".
Set "HDMI Control" to OFF.
• Please read the update instructions carefully before beginning.
• The firmware update should take 30 to 40 minutes. Once the update begins, don't turn off the
power supply to the A/V receiver until it is time to restart it.
• Depending on the conditions of the network, a firmware update via a network may take more
than one hour or even fail to finish. If the update is not completed within two hours, turn off
the power supply by pushing the ON/STANDBY button and then try updating again from
the beginning.
• Updating the firmware and adjusting the settings will be done automatically, but may take
some time to complete. Please follow the procedures as instructed when you update. Note
that the update may fail, or cause problems for your A/V receiver, if you do any of the
following:
• Pull out the A/V receiver’s power cord;
• Interrupt the power supply to the A/V receiver (e.g. if the breaker is tripped or if there is an
electrical outage);
• Insert or remove the LAN cable from a device in your network when updating over a
network;
• Insert or remove a USB memory device from the A/V receiver when updating via USB;
• Operate components connected to the A/V receiver via HDMI, such as a TV or a recording
device.
If your A/V receiver is damaged for any of the reasons above, an Integra service center will
repair the unit for a fee.
