3.13.3.2 Ring Tone Volume
Configure the ring tone volume level if the setting above is enabled.
3.13.3.3 Button Press Alarm
Generate the ring tone when pressing any key except the key with the volume adjustment.

3.14 Line-in Setting
The n-SPK Supports optional line-in audio input by an Aux-in wire. The related parameters listed as below should be configured if
this function is enabled.
3.14.1 Stereo Line In Loop Back
Enable or disable the line-in function. This setting is determined in Main Features page. The related hardware circuit is necessary
to support this function.
3.14.2 Line-in/SBC Priority
This setting determines the priority of audio sources. There are two audio sources that one is from an A2DP link and the other is
from line-in input. If these two play simultaneously, n-SPK will output the one as high priority upon this setting. For example, if it
has two sources at the same time and set line-in high priority, n-SPK outputs audio from line-in. And n-SPK changes the audio
source to A2DP unplugging the line-in at the moment.
3.14.3 Line-in Mute/Unmute
This setting determines whether the line-in audio can be muted. If it is enabled, the muted status is controlled by the button
events with Play function described in 4.9.6 Button Functions.
3.14.4 Line-in Silence Detection
This setting determines the silence detection with line-in. If it is enabled, the silence detection function will be activated to detect
the swing in line-in. The purpose is for saving power.
3.15 Amplifier Control Setting
The n-SPK outputs sounds with the external amplifier. To avoid outputting the unexpected noise when the CODEC is turning on
or off, it needs to tune the timing of CODEC on and off base on the property of external amplifier.
