The desired dosage should be entered on the number pad after pressing 

the ‘‘ENERGY’’ pad. Press ‘‘START’’ to begin operation. After the dosage 

is delivered, the Spectrolinker beeps four times and the display flashes 

‘‘END.’’ Open the door at this point, and the display will oscillate between 

‘‘DOOR’’ and ‘‘0.’’
 The Spectrolinker is designed to make repetitive operations easy. So, 

when the door is closed after an operation, the Spectrolinker remains in 

the ENERGY mode and displays the last energy dosage entered. To 

repeat the previous dosage, just press ‘‘START.’’
To alter a previously entered dosage, press ‘‘RESET,’’ enter the new value 

and then press ‘‘START’’ to begin the operation.
When the chamber door is opened during an operation, the display will 

oscillate between ‘‘DOOR’’ and the energy dose remaining. To resume the 

operation, close the door and press ‘‘START.’’ Otherwise, press ‘‘RESET’’ 

to return the electronics to the WAKE state.

2.  Optimal Crosslink Mode 

— When this is selected, the unit is 

 

pre-programmed to deliver an energy dosage of 120 millijoules per unit 

area (120,000

µ

J/cm

2

) and ‘‘1200’’ appears on the display. This is consid-

ered the optimal dosage for most membranes [1]. All the number keys are 

deactivated in this mode. Press ‘‘START’’ to begin operation. After the 

dosage is delivered, the Spectrolinker beeps four times and the display 

flashes ‘‘END.’’ Open the door and the display will oscillate between 

‘‘DOOR’’ and ‘‘0.’’

   To repeat the previous operation, just press ‘‘START’’ after you close the 

door. The Spectrolinker remains in the OPTIMAL CROSSLINK mode and 

displays ‘‘1200,’’ i.e., 120mJ/cm

2

. Otherwise, press ‘‘RESET’’ to return the 

electronics to the WAKE state.

   

When the chamber door is open during the operation, the display 

 

oscillates between ‘‘DOOR’’ and the energy dose remaining. To resume the 

operation, close the door and press ‘‘START.’’ Otherwise, press ‘‘RESET’’ 

to return the electronics to the WAKE state.

3.  Intensity Mode 

— To initiate this mode, press ‘‘INTENSITY’’ and then 

‘‘START.’’ The value displayed is the irradiance level at the center of the 

chamber. The unit remains on until ‘‘RESET’’ is pressed, returning the 

electronics back to the WAKE state. When the Spectrolinker is in the 

INTENSITY mode, the 

µ

W/cm

 LED lights. All the number keys are  

deactivated in this mode.
In this mode, the unit displays ‘‘BULB’’ when the intensity level falls below 

1,500 

µ

W/cm

2

, indicating that the UV tubes need replacement. When the 

chamber door is opened during the operation, the display oscillates 

between ‘‘DOOR’’ and ‘‘0.’’ Then, if the door is closed, the Spectrolinker will 

remain in the INTENSITY mode. Press ‘‘START’’ to resume operatioor 

‘‘RESET’’ to return the electronics to the WAKE state.
