INSTALLING THE SIGNAL AMPLIFIER

Always use the accessories and specified installation work parts.

Check the state of the installation parts. Not using the specified parts

will cause units to fall off, water leakage, electric shock, fire, etc.

Install at a place that can withstand the weight of the unit and install

positively so that the unit will not topple or fall.

When installing this unit, make sure that there are no children nearby.

Otherwise, injury or electric shock could result.
