Some of these procedures may expose you to hazardous voltages, which
could cause personal injury or death if contacted. Use standard safety pre-
cautions when working with hazardous voltages.
The Remote PreAmp connectors carry hazardous voltage. To prevent risk
of electric shock, connectors must be fully mated or safety covers must be
placed over the open connectors. Proper installation requires that the oper-
ator is protected from exposed voltages by insulation or barriers.
