We solder the Short land on PWB before shipment to protect laser diode. Open the short lands after you connect pick-up with your circuit by flat cable . When you unstrap the short solder for the laser diode protection in the condition which doesn't connect by a flat cable, the laser diode and OEIC may destroy by static electricity.

Be sure no dust or soil on handling and leaving. Because, dust or soil on the objective causes the remarkable damage. If the dust is on the objective, blow it away by clean air, also, if the dust or soil remain on the objective, clean by the cleaning liquid (B4) made by JCBINDUSTRY Ltd.
