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 the BKM-24N.

Note on using the BKM-20D/21D

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

rightmost slot.

When removing a BKM-20D/21D, always loosen all input adaptor screws and then remove in order from the rightmost slot, as shown in Figure 2.

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 input connectors board, or a cover plate fitted, as shown in Figure 3, the radiation shield of the BKM-

20D/21D may be damaged or detached (see Figure 4). Using the BKM-20D/21D with the radiation shield damaged or detached may result in electromagnetic interference. Always use care about the radiation shield.
