Page 9: Audible Indicators
Audible Indicators There are audible indications that signal the status of your scanner. These indications are dependent upon the decoder being used. The function of these indications may not work as described below if using a decoder not manufactured by Metrologic. When the scanner is in operation, it will provide warnings with audible indications. - Page 10 Signaux acoustiques Il existe des signaux acoustiques qui vous informent sur l'état du scanner. Ces signaux dépendent du décodeur que vous utilisez. Il peut arriver que les fonctions de ces signaux ne correspondent pas à celles qui suivent si vous utilisez un décodeur qui n'a pas été...
- Page 11 Akustische Anzeigen Es sind akustische Anzeigen vorhanden, die Ihnen Aufschluß über den Scannerstatus geben. Diese Anzeigen sind abhängig von dem von Ihnen verwendeten Dekodierer. Es kann sein, daß die Funktionen dieser Anzeigen nicht den nachfolgend angegebenen entsprechen, falls Sie einen Dekodierer verwenden, der nicht von Metrologic hergestellt wurde.
- Page 12 Segnali acustici Sono previsti dei segnali acustici che Vi informano sullo stato dello scanner. Questi segnali dipendono dal decodificatore da Voi utilizzato. Se utilizzate un decodificatore che non è stato fabbricato dalla Metrologic è possibile che le funzioni di questi segnali non corrispondano a quelle qui di seguito indicate. Se lo scanner è...

Page 17: Labels
Labels The MH941 is a CDRH Class II laser system and an IEC Class I Laser System. Your unit will have a CDRH Class II caution label and an LASERKLASSE 1 label affixed below the model number. The model number label is found on the bottom of the scanner’s head. -
Page 18: Ir Sensor Activation
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). The IR device remains active as long as power is applied to the unit. -
Page 19: Scan Field
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. -

Page 22: Maintenance
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. 2. Gently wipe the scanner window. -

Page 25: Appendix B
Appendix B MH941 Scan Head Pin Assignments Signal Name Function 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. - Page 26 Reserved 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. It is recommended that this signal be debounced for approx- imately 30 milliseconds.
