Question about Neonate Bc-8000dv

How can I mute only one of the two baby stations for a short time? The other one should continue to "alarm" loudly in case the baby also cries. For example, if I have to go to one child's room at night, I don't want my voice to be constantly transmitted to the parent. That's why I mute Baby Station 1. Baby station 2 is then always muted at the same time. (I have one parent station and 2 baby stations).
