OZL-45R-BA-e-1510 

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  information  to  select  the  correct  power  supply  is 
located  on  the  device,  on  the  rear  of  the  stand  base.  You  must  comply  with  this 
information.  If  you  do  not  comply  with  these  specifications,  then  fires  or  other 
damage to the device could occur. 
 
The main  switch 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.
