H. The LINE light for the line on
hold flashes slowly in green, and a double-beep sounds
every 30 seconds to remind you the call is on hold.
(To turn off the reminder beep, see “Turn Hold Reminder

on hold longer than 20 minutes, release Hold before

place the line on hold and activate the intercom.
