10. FOCUSING KNOBS Coaxial focusing system combines both the coarse and fine focus knobs on same shaft located
on each side of arm. Raise or lower stage to bring specimen into focus.
11. ILLUMINATION Built-in substage electric LED illuminator provides constant, reliable, pre-focusing illumination equal
to a 20 watt tungsten bulb. Powered by 3 rechargeable AA nickel metal hydride batteries, no power outlet or electrical
cord are needed.
12. CAMERA HOUSING Built-in WiFi camera with USB port on back for powering camera only.
ASSEMBLY
1. Eyepieces:
Remove the dust caps from eyepiece tubes. Using .90mm “L” hex wrench, loosen silver colored hex socket screw,
located approx. 2.5mm from top edge of tube. On tube with diopter adjustment, loosen only the silver colored hex
socket set screw located approx. 2.5 mm below top of tube. Insert eyepieces and tighten silver colored hex socket set
screws.
2. Specimen holder:
Rotate coarse focusing knob to move stage platform to its lowest position. Remove two knurled screws from
mechanical stage platform. Place specimen holder on stage and using the two knurled locking screws, attach
specimen holder to mechanical stage
OPERATION
1. Place microscope directly in front of you in a manner which permits you to comfortably look into the eyepiece. Note
that the head of microscope rotates 360
º
, permitting you to operate the microscope from the front or from the back,
whichever is most convenient for you. It also permits convenient sharing of microscope by more than one user, by
simply rotating head, without needing to move entire microscope.
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 recharger
into your AC wall outlet. Battery recharger is also 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”. The 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.
Note that your microscope can be used during recharging.
Simply turn “on/off” switch on back of
microscope base to “on” position and proceed as follows.
3. Interpupillary adjustment of head: Look through the eyepieces and move the eyepiece holder tubes by rotating them
on their axis. When a full field of view is observed through both tubes, and images blend into one, interpupillary
distance is corrected for your eyes. Check the interpupillary scale and note index reading for future reference, in case
other users will be changing this adjustment from time to time. Each person may have to adjust interpupillary distance
to receive the same image.
4. Rotate coarse focus knobs to move stage down (away) from objective lens as far as possible.
