Telephones and Consoles Description, Installation, and Operation
Volume control
One key with two toggle positions controls volume. Pressing the right
“volume up” or left “volume down” side of the key incrementally increases
or decreases the volume for the tone or sound which is currently active. The
volume settings are retained for subsequent calls until new volume
adjustments are made. If the telephone is equipped with a Display Module,
volume can be adjusted at any time with the setting displayed on the screen
(in Program mode).
Note: All Meridian Modular Telephones manufactured after June 1996
are compliant with the HAC volume-level requirements issued by the
FCC for handset volume control for the hearing impaired. The highest
volume-level setting provides 13.5 dB over nominal.
Handset volumes can be configured to return to nominal on a per-call basis.
You can adjust the volume of the following tones, while they are audible:
• ringing
• handsfree (M2616)
• handset/headset
• buzz
• on-hook dialing
When the telephone is disconnected, all volume levels will return to default
values upon reconnection.
When the telephone is operating on loop power alone, the highest (eighth)
step in volume cannot be reached (as seen when using Display in Program
mode).
Message Waiting lamp
Each Meridian Modular Telephone has a red triangle in the upper right-hand
corner that lights brightly to indicate a message is waiting. This LED is the
primary message waiting indicator and lets you know a message is waiting
