SERVICE 

ACCU-SCOPE

  

microscopes are precision instruments which require periodic servicing to keep them 

performing properly and to compensate for normal wear. A regular schedule of preventative maintenance 

by qualified personnel is highly recommended. Your authorized 

ACCU-SCOPE

  

distributor can arrange 

for this service. Should unexpected problems be experienced with your instrument, proceed as follows: 

 

1. Contact the 

ACCU-SCOPE

  

distributor from whom you purchased the microscope. Some problems 

can be resolved simply over the telephone. 

 

2. If it is determined that the microscope should be returned to your 

ACCU-SCOPE

  

distributor or to 

ACCU-SCOPE

 

for warranty repair, pack the instrument in its original Styrofoam shipping carton. If you no 

longer have this carton, pack the microscope in a crush-resistant carton with a minimum of three inches 

of a shock absorbing material surrounding it to prevent in-transit damage. The microscope should be 

wrapped in a plastic bag to prevent Styrofoam dust from damaging the microscope. Always ship the 

microscope in an upright position; 

NEVER SHIP A MICROSCOPE ON ITS SIDE

. The microscope or 

component should be shipped prepaid and insured.
