Safety AdviceWarning: CLASS 1 LASER PRODUCTAll the Optical Light Source versions contain Class 1 lasers. To avoid risk of serious eye damage, DO NOT look into the interfaces at any time.CautionWhen using the Optical Light Source, always take basic safety precautions to reduce the risk of fire, electric shock and injury to persons. These include the following:• Avoid using the tester during an electrical storm—there

is a remote risk of electric shock by lightning.• Use only the batteries supplied with the tester. See

Fitting and Using Batteries on page EN-8.• Do not dispose of batteries in a fire—they may

explode.

Issue 1 - 02/09 EN-1



• Disconnect all interface cables before removing the battery cover.

• Never remove the rubber cover of the case while the Optical Light Source is switched on or connected to the network.

Looking after your Optical Light SourceAlthough light and portable, the Optical Light Source is very robust and has been designed to operate in a typical outdoors working environment.To ensure reliable operation, avoid:• very high or low temperatures—the Optical Light

Source is designed to operate between -10°C and +60°C. You can store the unit safely between -25°C and +70°C. We recommend that you remove the batteries if you are going to store the Optical Light Source for a period of time.

• very wet conditions—the Optical Light Source is weather-resistant but not waterproof. You can use it in light rain when held vertically, but you should never immerse the unit in water.

• Do not attempt to open the Optical Light Source or you will invalidate your warranty.

To avoid damage, we recommend that you keep the Optical Light Source in its carrying case when you are not using it.Caution: Cleaning the Optical Light SourceDo not use solvents, strong detergents or abrasive materials to clean the Optical Light Source. Use only cleaning agents approved for use on ABS and polycarbonate plastics.

Looking after your Optical Light Source

English


Looking after the Optical Connectors• IMPORTANT NOTE

The ceramic tube inside the SC/FC/ST interchangeable adaptor is very fragile. Be careful not to damage it when changing the adaptors. Do NOT attempt to connect a cable ferrule directly into the tube without using one of the adaptors.

• If the output power decreases the connectors may need cleaning with the cotton swabs supplied using alcohol. If the problem persists contact your Trend Representative.

• When not in use make sure that you place the protective caps over the connectors.
