<Cautions for Safe Repair Work> The following cautions will prevent accidents in the workplace and will ensure safe products. *The symbols indicate caution is needed to prevent injuries and damage to property. The symbols and their meanings follow.
*The following symbols indicate two levels of cautions.
When you see this symbol, you have to be very careful.
When you see this symbol, you have to follow the instructions there.
Do not look squarely into the laser light Fuse Cautioncoming from the pickup. Always use a designated fuse.You may loose you sight. Use of an incorrect fuse may result in a fire.
Do not allow wiring to be caught in the Battery Cautionscrew/chassis. Use the designated battery.If wiring is caught in the screw/chassis, it may Confirm the correct polarity and seat of thecause a short circuit, resulting in a fire. battery.
An incorrect battery or an improperly connectedor seated battery may result in a fire.
High Temperature Caution Designated Parts CautionTouching the heat sink may cause severe burns. Look up the part list and ensure that only
designated parts are used to prevent problems oraccidents.
Reverse Power Supply Connections or Wiring CautionMisconnections Caution Ensure that the wiring is correct when rewiring to Reverse power supply connections or prevent problems with ignition/breakdown.misconnections may cause ignition problems andsmoke may result.
Soldering Caution Wear GlovesHot solder from solder splash may cause severe Wear gloves to prevent electrical shocks or injuryburns. from the end face of the metal.
If you ignore this symbol and handle the product incorrectly or unsafely,injury or only material damage may result.
