Help: Requesting
The Help Requesting feature allows you to alert a preselected station, while
you are in conversation. This is of value, for example, if you happen to find
yourself in a situation where you need help. The Help feature is operated while
your current call is in progress, without disrupting the call. Once you have
agreed upon a partner for the help procedure, a predetermined action can take
place between you and your partner when Help is activated.
Activating Help (while in conversation):

the destination number. The destination must be another
keyset equipped with a display.

destination.
