2. User manual The present user manual describes the design and use of the motor focus system There is a separate user manual for the stereomicroscope or macroscope For safety directions and for detailed information about the stereomicroscope or macroscope and how to clean it and about its stands illuminators and accessories please refer to the user manual for that instrument Safety concept Before you try to set up and use the motor focus system read e this user manual and in particular the safety notes e the user manual for your stereomicroscope or macroscope including the notes about safety and care Permitted uses The motor focus system is intended for the motor driven raising and lowering of the LEICA MS5 MZ6 MZ8 MZ12 MZAPO and MZ FLIII stereomicroscopes and of the LEICA M420 macroscope on Leica incident and transmitted light stands and on the large swinging arm stand and it replaces the mechanical drive housing The motor focus system consists of acolumn with motor focus mechanism atransformer with a power cable e amanual control and or a footswitch and or a PC interface kit Prohibited uses The use of the motor focus system in a different manner from that described in this user manual can lead to injury malfunction and damage e Do not fit different plugs e Do not attempt to modify the motor focus system e Do not dismantle any part of the motor focus system unless instructions for doing s
