Decoder adaptor priority
The table on the right shows which decoder adaptor
will be selected preferentially when more than one
decoder adaptor which can accept the NTSC or PAL
signal format have been installed in the monitor.
For example, when a BKM-24N and a BKM-27T are
installed and an NTSC signal is selected, the NTSC
signal connected to the BKM-24N's input connectors
and the NTSC signal connected to the BKM-27T's
input connectors are both processed by the decoder on

When installing the input adaptor in an input option
slot on the rear of the monitor, or fitting a cover plate
to an unused slot, always do such operation in order
from the rightmost slot, as shown in Figure 1. If a
BKM-20D/21D is already installed, first of all remove
it and then do the installing operation in order from the
When one of the input option slots on the rear of the
monitor has a BKM-20D/21D (optional) installed, if
the slot to the right has another adaptor or the analog
