Audio Volume Adjustment
There are 4 kinds of audio volume to be adjusted:
• Ringer Volume (on the speaker)
• Speaker
• Handset
• Headset
To adjust the volume, press the VOL key to invoke the volume adjustment screen. Then use the
UP/DOWN keys to increase or decrease the volume. The kind of volume to adjust is by context. When no
audio device is selected at the moment, the Ringer volume will be adjusted. Each UP/DOWN key press
will play a short burst of the current ring tone. If one of the audio devices is selected, then the volume
adjustment applies to that device. The screen will show why kind of volume is being adjusted with a
pictorial representation of the volume level.
Each volume has 16 steps in nonlinear logarithmic scale. Each setting is a 16-bit multiplier in the range
41 to 32764 in Q3.12 format (or 0.01 to 7.999 or –40 to 18 dB). Each step is equal to 58/(16-1) or 3.87
dB.
Additional volume settings can be added and accessed via the phone setup screens. These volumes are:
• DTMF Echo Volume (use <DTMF Playback Level>)
• Call Progress Tone Volume (setting the ToneScript for each tone)
Ring Tone
The SPA941 offers 10 ring tones. The characteristics of each ring tone is configurable using a RingScript
(see Section 3). In a RingTone script, the user can assign a name for the ring tone, and specifies 2
components for it:
