Troubleshooting
Most difficulties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difficulty, check the control settings, determine the cause of the
fault and make the necessary changes. If you are unable to get sound,
refer to the suggestions for the following conditions:
Power Indicator Is Not Lit
The power Indicator should be lit whenever the unit is plugged into the
wall power outlet and is pushed in. If it does not light, test the power
outlet with another electrical device, such as a lamp. Be sure the power
outlet being used is not controlled by a switch that has been turned off.
Network Does Not Work
If you have trouble connecting to your wireless network, check your network
setting carefully, these steps may help to resolve the problem.
1. Confirm that a Wi-Fi network works, ie, PC can access the Internet
using the same network.
2. Check that a DHCP server is available, or that you have configured a
static IP address on the unit. Please refer to Network Config section.
3. Check that your network’s firewall is not blocking any outgoing
ports.
4. Do a hard power off (unplug the AC mains) and let the unit restart the
network scanning cycle.
5. If using Wi-Fi connection, make sure the placement of your unit allows
it to receive the Wi-Fi signal.
No Sound
1. Check the cables between the output and the pre-amplifier inputs, be
sure they are connected properly. Refer to Fig. 2.
2. Music played from Internet Radio stations are affected by the speed
of your internet connection. If you find that music is cutting out regularly,
contact your internet service provider.
3. Make sure the station you selected is operating at the current hour.
The station can be broadcasting from a different time zone.
4. Make sure you select the correct type of internet connection either
wired or wireless.
