Installation of batteries
1. insert two AAA batteries into Remote control.
Make sure (+) and (-) are facing the proper
direction.
2. Replace the cover.
NOTE
• If the remote control will not to be used for a long
time, remove the batteries to avoid remote control damage.
CAUTION
Improper use of batteries can result in chemical leakage or explosion. Be sure to follow the instructions below.
• Do not mix batteries of different types. Different types of batteries have different characteristics.
• Do not mix old and new batteries. Mixing old and new batteries can shorten the life of new batteries or cause
chemical leakage in old batteries.
• Remove batteries as soon as they have worn out. Chemicals that leak from batteries can cause a rash. If you find
any chemical leakage, wipe thoroughly with a cloth.
• The batteries supplied with this product may have a shorter life expectancy due to storage conditions.
• If you will not be using the remote control unit for an extended period of time, remove the batteries from it.
Note on disposing batteries:
The batteries provided contain no harmful materials such as cadmium, lead or mercury.
Regulations concerning used batteries stipulate that batteries may no longer be thrown out with the household
Rubbish. Deposit any used batteries free of charge into the designated collection containers set up at commercial
Businesses.
Using the remote control unit Bundling the cables
Use the remote control unit by pointing it towards the

Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed. This
is not a malfunction, and the unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a
heater, as this may cause the cabinet to deform and the LCD panel to malfunction.
• Storage temperature: +5°C to +35°C.

1.2. U6102 (TPA3124D2PWPR)
Description
The TPA3124D2 is a 15-W(per channel);efficient,class-D audio power amplifier for driving stereo speakers in a single-ended configuration;or a
mono speaker in a bridage-tied-load configuration .The TPA3124D2 eliminates the need for an external heat sink when playing music.
The gain of amplifier is controlled by two gain select pins.The gain selections are 20.26.32and 36dB.
The patented start-up and shutdown sequences minimize pop noise in the speakers without additional circuity.
Features
10-W/Ch Into a 8-Ω Load From a 24-V Supply
15-W/Ch Into a 4-Ω Load From a 22-V Supply
30-W/Ch Into a 8-Ω Load From a 22-V Supply
Operates From 10V to 26V
Can Run From +24V LCD Backlight Supply
Efficient Class-D Operation Eliminates Need For Heat Sinks
