Additional feature keys
Message Waiting lamp key
Each telephone has a red message waiting LED just above the hold and Rls
keys that lights to indicate a message is waiting. This LED is the primary
message waiting indicator and lets you know that a message is waiting,
regardless of whether the telephone has a message waiting key/lamp pair.
You must have Message Waiting allowed Class of Service. See LD 11,
Software Input/Output: Administration (553-3001-311) and Software Input/
Output: Maintenance (553-3001-511).
If you do assign a message waiting key/lamp pair, there will be two
indications of a message waiting:
— the red Message Waiting LED lights
— the LCD associated with the Message Waiting key blinks
Autodial key
You can assign an Autodial Key that dials the message center (or voice mail
system) to avoid the double indication or have no key/lamp pair assigned to
the message center.

LCD indicators that can be assigned to any combination of directory numbers
and features. The M3820 has 13 fully programmable feature keys; the M3310
has seven, and the M3110 has eight. The lower right-hand key (key 0) is
reserved for the Primary DN.
