How to operate
Clap your hands once facing towards the TV. If the TV detects a clap, the
power lamp will blink once.
If the power lamp does not blink, clap harder or go closer to the TV and clap
again. Once you confirm that the power lamp blinks, now try operating the
TV by clapping your hands. Clap your hands twice or 3 times (depending on
your purposes) with an interval of 0.5 seconds.
0.5 seconds
To turn the TV on/off (standby), repeatedly clap your hands 3 times.
If the TV properly detects the command, you will hear a beep and the TV
turns on/off.
To mute/unmute the TV, repeatedly clap your hands twice.
If the TV properly detects the command, you will hear a beep and the TV
enters mute/unmute.
Depending on the volume or the interval of your clap, the TV may not

detect a command properly and may show no reaction. When you try to
turn on/off the TV, the TV did not detect the third clap and the TV enters
mute/unmute.
Try several times until you master it. Especially when clapping for 3 times,
try to maintain the same interval with the first and second clap to the
second and the third clap so that the TV can detect the correct command.
