If all the parameters for the incoming signal are good but there are still problems
with the picture or sound quality it is likely that there is a problem with the cable
that connects the TV / VCR to the MyM.
8.2.3.2 Antenna quality
The MyM has an inbuilt spectrum analyser. This
shows the level of the incoming signals on the VHF
and UHF band (47 to 862 MHz). The picture to the
right shows the signal level of the incoming
channels. The two chosen muxes for the installed
channels are green. The recommended level for the
incoming channels is between 35 dBµV and 75 dBµV
(between the 2 red horizontal lines).
Check that the green columns are between the 2 red horizontal lines. If not it may
be necessary to adjust or upgrade the TV aerial.
8.2.5 Channel indicator
The MyM Channel indicator can be switched between
on and off. When the channel indicator is on, a text
box with ”MyM 1” will be shown in the upper right
corner of the picture. After installation the channel
indicator is automatically switched on for 8 hours to
make it easier to do a channel search on the TV.
During normal operation, the channel indicator is off.
