Do not look squarely into the laser light coming from the pickup.

You may loose you sight.

Caution

Do not allow wiring to be caught in the screw/chassis.

If wiring is caught in the screw/chassis, it may cause a short circuit, resulting in a fire.

Fuse Caution

Always use a designated fuse.

Use of an incorrect fuse may result in a fire.

High Temperature Caution

Touching the heat sink may cause severe burns.

Reverse Power Supply Connections or

Misconnections Caution

Reverse power supply connections or misconnections may cause ignition problems and smoke may result.

Soldering Caution

Hot solder from solder splash may cause severe burns.

Battery Caution

Use the designated battery.

Confirm the correct polarity and seat of the battery.

An incorrect battery or an improperly connected or seated battery may result in a fire.

Designated Parts Caution

Look up the part list and ensure that only designated parts are used to prevent problems or accidents.
