14 Labels The MH941 is a CDRH Class II laser system and an IEC Class I Laser System. Your unit w ill have a CDRH Class II caution label and an LASERKLASSE 1 l a bel affixed below the model number. The model number label is found on the bottom of the scanner’s head.
15 Figure 3 IR Sensor Activation This function is decoder/controller dependent. The scanning process is initiated by an infra red (IR) device that is found below the laser output window. The signal it projects extends approximately eight (8) inches beyond the output window (Refer to Figure 3) .
16 Figure 4 Scan Field The depth of field for the scanner is from the face of the output window to five (5) inches (Refer to Figure 4). If the scanner is in the stand, a bar code must be presented to the scanner. When holding the scanner, position the output window within five inches of the bar code.

19 Maintenance Smudges and dirt can interfere with the proper scanning of a bar code. Therefore, the output window will need occasional cleaning. 1. Spray glass cleaner onto lint free, non-abrasive cleaning cloth.
20 Appendix A Specifications Application: Hand-Held Laser Scanner Light Source: VLD 675 ± 5nm CDRH: Registered with CDRH, Class II laser product Maximum radiant power less than 1 mW IEC: IEC 825 Class I laser product Maximum radiant power less than 0.
21 Operational Depth of Field, UPC 100%: Up to 125mm (5") from face Scan Speed: 38 scan lines per second Scan Pattern: Single scan line Maintenance Required: Clean output window periodically Print Contrast: 35% minimum reflectance difference Roll, Pitch, Yaw: 42 E , 68 E , 52 E The following operations are decoder/controller dependent.
22 Appendix B MH941 Scan Head Pin Assignments Pin Signal Name Function 1 Flip Sense A square wave output signal that changes polarity when the scan mirror drive circuit changes the motor direction. The frequency is approximately 19 Hz to achieve a nominal 38 flips/scan per second.
23 4 Reserved 5 Proximity Detect The proximity detect is a momentary grounding switch. The controlling computer should provide a +5±.25 VDC pull up which can be grounded when the proximity detect activates. This indicates that an object has moved within scanning rage.
