Symptoms Causes Remedies
FM/AM TUNER
Crackling noise on both
AM and FM stations.
Noise caused by fluorescent lamp being
turned on and off. Move antenna as far as possible from the fluores-
cent lamp.
Noise from automobile ignition.
Install an FM outdoor antenna as far as possible
from the road (See page 15).
Change the position or direction of the outdoor antenna.
Stereo indicator lights, but
sound is distorted and ste-
reo separation is bad. Station is too strong. Change to FM indoor antenna (See page 14).
Multiple reflection of the radio waves
because of tall buildings or mountains. Use antenna that has better directivity and orient it
so distortion decreases.
Indicators for stereo recep-
tion flicker and hiss is
heard on FM stations. Station is too weak. Install an outdoor FM antenna (See page 15).
Stereo FM broadcasts cover only about
half the distance of an ordinary broadcast. Change the position or direction of the outdoor
antenna (See page 15).
No preset station is
recalled. Memory is lost because power has been
turned off for a long time.
Store all stations again (See page 49).

NET A
UDIO
Fails to activate the Inter-
net radio or music server
feature.
Imperfect network connection.
Check the connection between this unit and the LAN
side port of your router (gateway) (See page 73).
Make sure that the modem and router (gateway)
are correctly connected. Also, make sure that the
power is on (See page 73).
Make sure that the Network Setup is configured
properly (See pages 76 to 79).
The playback sound dis-
continues while using the
Music Server.
Excessive load on the network or server.
Or processor-intensive applications
including word processor and spreadsheet
are running.
Make sure that your system satisfies all the system
requirements listed on page 72.
When you play WAVE files on multiple DTR-7.4,
the playback sound may discontinue because of net-
work overload. In this case, deploying another inde-
pendent LAN dedicated to the Net Audio to separate
it from the general LAN connection, or adding a
switching hub or router to improve network traffic
may resolve the problem.
The unit fails to obtain a
station list from an Inter-
net radio site (via the XiVA
internet Radio Service).
The radio site is now out of service or oth-
erwise inaccessible due to some other rea-
son such as maintenance.
Try to access the site again at a later time.
