Install an FM outdoor antenna as far as possible
from the road (See page 15).
Change the position or direction of the outdoor antenna.
Change to FM indoor antenna (See page 14).
Use antenna that has better directivity and orient it
so distortion decreases.

PONENT VIDEO OUT connectors (See page 20).
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).
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.
Try to access the site again at a later time.
