Use the ON/OFF switch "A" (ON/OFF) on the headphones only to switch them on and off.
If there is no incoming audio signal, the transmitter base will switch off automatically.
To adjust listening volume, use only the wheel "C" on the headphones, and not the volume of the TV
After switching off the headphones, place them back in the charging slot "M" on the base, making sure the LED "Q"
comes on. This will ensure they are already charged the next time you use them.
If the headphones are not being used for a long period of time it is advisable to disconnect the AC power adapter from
the power outlet.
MICROPHONE: The HP Steto Digital headphones have a built-in microphone: it is sufficient to press the "D" (MIC)
button to stop listening to the audio signal from the device connected and to amplify the voices and sounds around
you; the "B" light will come on red when the MIC is active. To resume normal listening of the source connected to the
headphones, press the MIC button again; the "B" light will turn green again.
To recharge the batteries, move the on/off switch "A" of the headphones to OFF and place them back on the base,
making sure the LED "Q" lights up.
The LED "Q" is red while charging; it will turn green when the battery is fully charged. The charge can last for up to 3
hours.
A spare battery is supplied for prolonged use. Just insert it into the slot "S" on the base to charge it. While the spare
battery is charging, the LED "R" is lit red. It will turn green when the battery is fully charged.
With a fully charged battery, the headphones are guaranteed to work for at least 4 hours.
The headphones can be left charging on the base even for several days.
WARNINGS:
When the headphones are not being used, it is advisable to switch them off to avoid running down the batteries and
damaging them.
Make sure the slider "A" is moved to OFF while the batteries are charging.
