hold it down with the stage clips.
Focusing

path. Make sure you hear a click that confirms it is in place.
2. Push the stage clips to insert a specimen slide.
3. Looking through the eyepiece, turn the coarse focuser knob to focus on the specimen until it
comes into focus.
Changing magnification

click confirming the selected magnification is secured.
1. Ensure your specimen is sitting directly under the objective lens.
2. Rotate the focuser knob until the image comes to focus.

microscope has been switched off for at least 15 minutes.

2. Carefully remove the old bulb
3. Use a clean cloth to hold and insert a new bulb into the socket

duration of the bulb.
