To store a traverse position, press one of the storage buttons and hold it 
down a few seconds until the button light goes off. This will store the 
current traverse position and the LED settings in the selected storage cell. 

Note

:

   There are a total of 10 preset positions available on via the uScope 

 

software. 

In LIGHT mode

, the buttons A

D represent four LED channels, labeled A-D. 

The 24 LEDs in the illuminator module are divided into four channels, which 
can be controlled individually. When a LED bank is selected, the 
corresponding button lights up. One or more LED banks can be selected 
simultaneously by pressing the one or more of the A

D buttons.  

Note

:

   When an EPI Optics Module is installed in the SVM, the EPI 

 

illumination is controlled using front panel button D, and front 

 

panel button B controls illuminator channels B and D. 

 

Keypad 

In SITE mode

, the four buttons will move the traverse in the 

x

 and 

y

 

directions. Pressing a button will start the traverse motor at low speed, and 
after about two seconds motor speed slowly ramp up to high speed. 
Pressing the button briefly allows single stepping of the traverse. 

Pressing the center button (Stop) will immediately stop any traverse 
movement which may be in progress.  

In LIGHT mode

, the up/down keys will increase/decrease the intensity of 

those LED banks which are selected by the A

D buttons. One or more of the 

LED banks can be controlled simultaneously. 

Pressing the center button (Stop) with switch off all selected LED banks.  

 

Focus 
up/down 

These buttons will move the focus motor up or down to focus the image. 
The focus motor will start at slow speed and then ramp up to high speed. 

 

Lock 
indicator 

The lock indicator LED on the front panel is green when an optics module is 
detected in the SVM340 and the SVM340 traverse is not moving.  

The Lock indicator LED turns red when an Optics Module is not detected in 
the SVM340, or then the SVM340 traverse is in motion.
