1. E 39 Appendix F Patents m 41 Ee alee eee ea eee 42 iv INTRODUCTION The MS6720 is the first laser bar code scanner to truly bridge the gap between omnidirectional fixed projection and hand held scanners It incorporates fixed projection performance and patented 20 line scan pattern into the comfortable ergonomic styling of our popular hand helds The MS6720 utilizes a unique patented infrared sensor and control scheme for hands free projection scanning and fatigue reduced hand held operation Whether operators choose to present small items to the scanner or transport the lightweight scanner to bulkier items the compact size and comprehensive scan pattern make the MS6720 the perfect choice for many applications For increased flexibility there are three optional stands available The stationary stand is ideal for applications where the MS6720 is being used as a hand held scanner Or if a customer application requires more in stand scanning Metrologic s adjustable stand provides 7 rotational and 9 tilting positions while still providing the option for hand held scanning If countertop space is an issue there is an optional bracket for a wall mounting that can be used with the adjustable stand cup The MS6720 features both short range and long range activation user friendly programming reliability and versatility Operators are sure to appreciate the convenience and flexib2. laser product The following is an example of this label 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 Metrologic Instruments Inc Blackwood New Jersey USA Complies with 21 CFR Chapter 1 subchapter J KCNN 948 ITE Warranty VOID if case opened Contains no user serviceable components CAUTION Laser light when open DO NOT STARE INTO BEAM This device complies with FCC Class B See manual Manufactured Blackwood NJ September 2000 Model MS6720 R8232 Barcode 553504 5V Serial 30003701 109 EN60825 1 1994 ALL 1996 0 68 milliwatt peak Class lla Laser Product Avoid Long Term Viewing of Direct Laser Light U S Patents 15 216 232 45 340 973 5 484 992 5 468 951 5 340 971 5 424 525 5 260 553 45 525 789 5 528 024 5 255 789 5 557 093 2 Gently wipe the scanner window 15 DEPTH OF FIELD SPECIFICATIONS Normal Depth of Field 0 0 0mm joe mm 1 1 25 4 0057 144mm 2 2 2 50 8mm 0063 0104 264mm 160mm 3 76 2mm 0068 NI yu pi eae 4 101 6mm 5 127 0mm 0164 o SS ne 406mm 6 152 4mm 021 533mm ee e 7 177 8mm
