2.1 Connecting Connectors 2.1.2 Connecting SC-Type Connector Insert the end face (ferrule) of the optical fiber cable into the connector adapter on the 3662-20/ 3663-20. Make sure that the protrusion of the cable connec- tor fits into the hole of the connector adapter.
2.2 Turning ON/OFF Power 2.2 Turning ON/OFF Power Power ON Turn on the power switch. The laser output indicator will light up or start blink- ing and the laser output connector will output a laser beam. If the battery replacement indicator is blinking when power is turned on, the battery is running low.

9734 SC CONNECTOR ADAPTER ADAPTER Detaching Procedure 1. Push the lock lever to the front of the 3662-20/ 3663-20 to unlock. 2. Gently draw out the connector adapter. Be sure to replace the cap of the 3662-20/3663-20 and the adapter's dust cap for protection against damage and dust when the 3662-20/3663-20 is not in use.
Attach both ends of the strap securely to the instrument. If insecurely attached, the instrument may fall and be damaged when carrying. Attaching the strap 3662-20(3663-20) Pass the strap through the strap hole of the 3662-20/ 3663-20 as shown in the fig- ure.
If there is dust in the interface or a scratch on the optical output connector ferrule, the 3662-20/3663-20 may not satisfy perfor- mance specifications. • When cleaning the optical output connector, make sure that power to the laser source is off.

4.4 Cleaning Always clean the optical connector end face (ferrule) optical fiber cable before connecting. 1. Detach the connector adapter. 2. Gently wipe the laser output connector (ferrule, end face) and the surrounding area using a new cotton swab, a soft lint-proof cloth, or an optical connector cleaner (stick).
When cleaning the end of the optical connector, do not apply too much force with the cleaning cloth. This may result in damage to the connector and the 3662-20/3663-20 may consequently fail to sat- isfy performance specifications. 1. Squeeze the lever of the 9738 OPTICAL CON- NECTOR CLEANER and the shutter will open, revealing the cleaning cloth.
• When sending the product for repair, remove the batteries and pack carefully to prevent damage in transit. Include cushioning material so the instrument cannot move within the package. Be sure to include details of the problem. Hioki can- not be responsible for damage that occurs during shipment.
