Notes
• This function can be used only when all the versions of VM-3000VA firmware, VM-3000E firmware, and
VM-3000 Setting Software are 2.00 or later.
• Since broadcast sound volume increases because attenuators are bypassed when the speaker line
surveillance is performed during broadcasts, it is recommended that the time and intervals be set for the
time zone in which no broadcast is scheduled.
