Service mode
DTV stands for digital television broadcast. In analog broadcast, the worse the reception condition gets, the more noises and
ghosts occur on the screen. In digital broadcast, on the other hand, there is no degraded images up to a certain level. Once the
reception condition drops below a limit, however, both picture and sound are interrupted suddenly. With DTV sets, it is thus very
difficult to know how well the radio wave is received by viewing the screen. To cope with this problem, the service mode provides
for useful information on signal reception condition on the screen.
Note : Service mode screen is update at every 5 seconds, so there are some time lags between actual condition and screen.
1) Service mode screen and switching
There are four screens for the service mode. Press the SELECT key on the set or the R/C unit, and at each push the four
screens get switched alternately.
2) Limitations with the service mode
In the service mode, channels can be selected just directly or with the CH UP/DOWN keys. Any other ways channel selection
