Frequently Asked Questions

Cannot Connect
Make sure that any firewall has port 23 (telnet) enabled. Check that the device is powered on and not busy. Check you have specified the correct IP address.

Function Not Working
The AVR603 software has been written for the Marantz CR603 CD receiver and has only been tested on this device. However the protocol used is common to most Denon and Marantz devices so most functions will work on other devices.
