Powering On/Off And Charging; Volume Adjustment - Sena NS10 User Manual

1. POWERING ON/OFF AND CHARGING

1.1 Powering On
Press the Center Button and the (+) Button at the same time for 1 second to power on. The blue LED turns on and you
will hear ascending beeps and "Hello".
1.2 Powering Off
Tap the Center Button and the (+) Button simultaneously (you don't need to press and hold in order for the system to
power off). The red LED turns on for about 2 seconds until it turns off completely and you will hear "Goodbye" and
descending beeps.
1.3 Charging
The charging LED beside the charging port turns on red while charging, and turns to blue when the headset is fully
charged. It takes about 2.5 hours to be completely charged. You can use the NS10 while charging. It is especially helpful
when you use a cigarette charger for a long road trip.
1.4 Low Battery Warning
When the battery is low, the blinking blue LED in stand-by mode turns to red and you will hear mid-tone triple beeps and a
voice prompt, "Low battery".
1.5 Checking the Battery Level
You can check the battery level in two different ways when the headset is powering on.
1.5.1 LED Indicator
When the headset is powering on, the red LED flashes rapidly indicating the battery level.
4 flashes = High, 70~100%
3 flashes = Medium, 30~70%
2 flashes = Low, 0~30%
1.5.2 Voice Prompt Indicator
When you power on the headset, keep pressing the Center Button and the (+) Button simultaneously for several seconds
until you hear high tone triple beeps. Then you will hear voice prompt indicating the battery level. However, if you release
the buttons as soon as the headset turns on, you will not hear the voice prompt of battery level indication.
