Note:
• Plan your requirements as the ring assignment is the most important operation of your telephone
system.
• Try to keep the number of ring modes to a minimum, three per day is sufficient (normal day working,
lunch times and evenings for example). You may want to add an additional mode to cover the
weekend.
• Do not have too many phones in a ring group. Remember that calls can be answered by pressing
the Function Keys at the SL2100 phones. See also Call Pickup in the Features & Specifications
Manual.
