Light Sources
The Epi-White button controls the Epi White illumination. Press the button to turn ON Epi-
White; press the button again to turn it OFF. Epi illumination will automatically turn off after
15 minutes, unless the Hold button is activated. When the UV transilluminator switch is
activated Epi-White is automatically turned off.
The White Light Trans button controls the White Light Transilluminator when installed
(optional). It will automatically turn off after 15 minutes, unless the Hold button is activated.
The UV Trans button controls the UV Transilluminator with full intensity. The
transilluminator will automatically turn off after 15 minutes unless the Hold button is
activated. For safety purposes, this switch is subject to the following automatic controls:
•
It is automatically turned off when the front door is open.
•
It is automatically turned off when the drawer is open.
If the door or drawer is opened while the transilluminator is ON, the blinking LED will warn
you that the transilluminator has been turned OFF. After the door or the drawer is closed, you
have to press the UV Trans switch again to turn it ON.
Important: For the purposes of band cut applications, it is possible to
turn ON the UV light with the drawer fully open. You must wear all possible UV
protections, especially for your eyes, when the transilluminator switch is turned ON
with the drawer fully open. The UV shield has to be used but glass or mask and gloves
are recommended to block the UV radiations. This option is not applicable to the door.
Wichtig: Wer die Absicht hat, Banden aus dem Gel zu schneiden, kann bei
eingeschaltetem UV-Licht die untere Schublade oeffnen. Sie muessen Schutzkleidung
und die notwendigen UV-Schutzmassnahmen tragen, besonders Augenschutz, wenn der
transilluminator bei offener Schublade eingeschaltet ist. Das Plexiglasschutzschild muss
benutzt werden, ebenso Schutzbrille oder Schutzmaske und Einmalhandschuhe, um sich
vor der UV-Strahlung zu schuetzen. Diese Moeglichkeit ist von der Geraetetuer aus
nicht anwendbar.
The UV Prep switch is used to decrease the light output of the UV Transilluminator. The UV
Preparative function is a lower intensity light designed to minimize the effects of UV
exposure on DNA. The Preparative mode is recommended for applications that require longer
UV exposure times. In order to activate the UV Prep switch, the UV Trans button must be
on.
The Hold key disables the automatic shut-off of the UV and White light transilluminators and
the Epi-illumination; the lights will remain active until the hold status is cancelled. When the
Hold key is pressed, the orange LED lights, indicating that the Hold function is active.
