VOKKERO® Guardian - Standard terminals (References VO8150AA / VO8152AA), have 4
groups from 1 to 4 (Gr1 to Gr4).
VOKKERO® Guardian - Plus terminals (References VO8154AA / VO8156AA), have 3 groups
from 1 to 3 (Gr1 to Gr3).
Group 0 links all available groups.
Thus, the terminals in groups 1 to 4 can only hear and speak with the members of their group.
Group 0 terminals (Gr0) can hear and speak with all groups.
When you change groups, a beep in the accessory's loudspeaker signals that the terminal has
taken the change of group into account.
A double beep signals that you have reached the upper or lower limit.
Check the number of the selected group on the terminal's LCD.
