Before use 

1.1  General notes 

You must open the packaging carefully, to make sure that none of the accessories in 
the packaging fall on the floor and get broken. 

In  general,  microscopes  should  always  be  handled  carefully  because  they  are 
sensitive  precision  instruments.  When  using  or  transporting  the  microscope  it  is 
particularly  important  to  avoid  abrupt  movements,  as  this  may  damage  the  optical 
components. 

You  should  also  avoid  getting  dirt  or  finger  prints  on  the  lens  surface,  because  in 
most cases this will reduce image clarity. 

To maintain the performance of the microscope, it must never be disassembled. So 
components  such  as  lenses  and  other  optical  elements  should  be  left  as  they  were 
before use. Also the electrical parts in the base of the device must not be tampered 
with, as in this area there is an additional risk of triggering an electric shock. 

1.2  Notes on the electrical system

 

Before connecting to a mains power supply,  you must make sure that you are using 
the  correct  input  voltage.  The  mains  cable  supplied  has  an  external  power  supply. 
The  necessary  values  are  shown  on  this  power  supply.  If  you  do  not  comply  with 
these specifications, then fires or other damage to the device could occur. 

The lighting switches must also be switched off before the mains cable is connected. 
In this way you will avoid triggering an electric shock. 

If you are using an extension cable, then the mains cable you use must be earthed. 

When carrying out any procedures whereby you come into contact with the electrical 
system of the device, such as, for example, changing the bulb, only carry out these 
procedures when the power is disconnected.
