Using music mode
To optimise the SP for music reproduction, the device can be placed into music mode.
This is done by holding down the mute microphone button for five seconds until the red LEDs around it light up whilst the SP is connected to a music playing device via the 3.5 mm jack. If connected via USB to a music playing device, the SP should already be optimised for music reproduction.
If during this time a softphone call via USB is detected, the SP will automatically change to normal speech mode. Once the call is terminated, the SP will also automatically return to music mode.
