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.
