automatically turns off during charging.
3.5 Low Battery Warning

to red and you will hear a voice prompt, “Low battery”.
3.6 Checking the Battery Level
You can check the battery level in two different ways when the headset

indicating the battery level.
4 ashes = High, 70 ~ 100%
3 ashes = Medium, 30 ~ 70%
2 ashes = Low, 0 ~ 30%

Tufftalk Lite
3.6.2 Voice Prompt Indicator
When you power on the headset, keep pressing the Center Button and
the (+) Button simultaneously for 3 seconds until you hear three, high-
toned beeps. Then you will hear a voice prompt indicating the battery
level. However, if you release the buttons as soon as the headset turns
on, you will not hear a voice prompt for the battery level indication.
3.7 Volume Adjustment
You can easily adjust the volume by tapping the (+) Button or the (-)
Button. You will hear a beep when the volume reaches the maximum or
minimum level. The volume is set and maintained independently at
different levels for each audio source even when you reboot the
headset. For example, once you set the volume for mobile phone
handsfree, it will not change even if you adjust the volume for your
Bluetooth MP3 music. However, if you adjust the volume during stand-
by mode, it will affect volume levels of every audio source.
WARNING
Use of the product at a high volume for a long period of time may damage
your eardrums or hearing ability. Keep the volume at a modest level to
prevent damage.
4 PAIRING THE TUFFTALK LITE WITH
BLUETOOTH DEVICES

You can pair the Tufftalk Lite with Bluetooth mobile phones, Bluetooth
stereo devices such as MP3 players and with other Sena Bluetooth
headsets. The pairing operation is required only once for each
Bluetooth device. The headset remains paired with the devices and
automatically reconnects to them when they are within range. You will
hear a high-toned single beep and a voice prompt whenever the
headset reconnects to the paired device: “Phone connected” to a
mobile phone, “Media connected” to a Bluetooth stereo device.
