15.  TENSION ADJUSTMENT COLLAR: Used to adjust tension of focusing mechanism. 
 
16.  SAFETY RACK STOP:  When properly adjusted, controls maximum upward travel of stage.  Prevents higher power objectives 

from breaking specimen slides, prevents damage to objective lenses.  This stop has been pre-adjusted at the factory. 

 
17.  RECHARGER:   Automatic switching charger used to recharge batteries.  The auto recharger will accept 120v to 240v current, 

either 50H or 60H, without the need for any additional transformer. 

 
18.  USB CABLE: Connects microscope & camera to computer. 
 

ASSEMBLY

 

 

 

 

1.  SPECIMEN HOLDER: 
 

A.  Rotate coarse focusing knob to move stage platform to its lowest position. 
 
B.  Remove two knurled screws from mechanical stage platform. 
 
C.  Place specimen holder on stage and using the two knurled locking screws, attach specimen holder to mechanical stage. 
 

OPERATION

 

 
Your microscope is fully functional as a standard microscope.  The following instructions apply only to operation of the microscope.  
Refer to the software instructions located on the Motic Images CD for operation of camera.  Some steps for microscope operations 
are altered slightly in the software documentation, in order to utilize some of the unique features provided by the digital camera and 
software. 
 
1.  Place microscope directly in front of you in a manner which permits you to comfortably look into the eyepiece and easily reach 

the focusing controls 

 

2.  Assure that light is available for illuminating the specimen. 
 

A.  Your microscope has special LED illumination that is powered by 3 rechargeable AA nickel metal hydride batteries 

(supplied).  These batteries may be recharged, as required, using the recharger (supplied).  Each set of batteries may be 
recharged approximately 500 times before replacing, and each charge will provide up to 50 hours of microscope 
operation.  The LED component (bulb) will last for up to 50,000 hours before replacement is required. 

 

WARNING:  DO NOT USE regular AA alkaline batteries.  Use of other than rechargeable AA nickel metal 
hydride batteries could result in batteries exploding during recharge.  ONLY USE THE SUPPLIED 
SWITCHING BATTERY RECHARGER WITH AUTOMATIC “TRICKLE CHARGE”. 

 

B.  It is recommended that you charge the batteries before initial use and after prolonged storage as the batteries may have 

discharged.  Plug output cord from battery charger into DC recharging socket located on back of microscope base.  Your 
automatic switching recharger operates on 100 to 240 volts AC 50/60 Hz. Plug charger into your AC wall outlet.  Battery 
recharger is equipped with an automatic “trickle charge” feature; the red LED indicator lamp located on recharger will be 
illuminated when batteries are receiving maximum charge.   After batteries are charged, the red LED indicator lamp will 
turn to green and charger automatically switches to “trickle charge”.   Note that your microscope can be used during 
recharging.  Charger can be left plugged in, but for safety reasons it is a good idea to disconnect the charger from the AC 
wall outlet and the output cord from recharging socket after 12 hours.  Batteries and charger may feel warm when 
charging, and unplugging the recharger is a safety precaution.   

 

C.  Turn “on/off” switch located on microscope base to “on” position and proceed as follows.
