ringing
When the telephone is disconnected, has maintenance performed on the
loop, or a restart occurs, both speaker and alerting tone levels return to their
default values upon reconnecting.
When the set is operating on loop power alone, the highest (eighth) step in
volume cannot be reached (as seen when using Display in Program mode).
For those hearing-impaired applications where an amplifier is appropriate,
the MSL-100 NT TONE (NT8UX06-03) is available.

Hold key

The Meridian modular telephones provide a dedicated key for placing calls
on hold:
To place a call on hold, press the Hold key. The line indicator for the
line being placed on hold flashes.
To take a call off hold, press the line key on which the call resides as
identified by the flashing indicator.

Release key

The Release key (Rls key) is the orange key that is located above the set's
Hold key and to the right. The purpose of the key is to release a call from
the telephone set. Use the Release (Rls) key as an alternative to placing the
handset on-hook. Whenever you dial on-hook and get a busy signal or no
answer, simply press the Rls key, and the telephone set disconnects the call.
Also use the Rls key to terminate a handsfree call.

Handsfree (M2616, M2616CT and M2008HF)

The handsfree feature on the M2616 set is software-assigned. It allows the
user to talk to another party without lifting the handset. To activate
handsfree, press the handsfree/mute key (Key 16, top left) or select a DN
without lifting the handset. When the handsfree feature is activated, the
LCD remains lit. To deactivate the handsfree feature, pick up the handset, or
end the call by pressing the Rls key. If the calling party disconnects before
the handsfree user disconnects, the handsfree feature remains enabled unless
the user presses the Rls key.
Note: If handsfree is not software-assigned, you can assign any other
feature to Key 16. The M2616CT handsfree feature is automatically
assigned and cannot be removed.
During a handsfree mute call, the microphone is deactivated but the speaker
remains active, preventing the other party from overhearing local
conversations. The handsfree LCD indicator flashes while the microphone
