The Leica SM2500 offers the option to automatically trigger a photocamera shutter each time the specimen sledge reaches a preselected photo posi­tion.
The connecting cable leading from the camera to the Leica SM2500 must be configured individually, depending on the type of camera used.
For on this option, please contact your local Leica office or the manufac-
turer Leica Biosystems Nussloch directly.

Daily routine work:
The control panel overview (chapter 5.3 on pages 20/21) will be a useful tool for your daily routine work.
Instruction manual V 1.3 – 10/2007

5.2 Switching the instrument on

Switch on the mains switch (0/I) located at the rear side of the control panel (On = switch position ‘I’):
All control elements on the control unit will emit light for about 2 secs. Next, the software version is displayed in the section counter (no. 44,
upper display in functional area 4 - chapter 5.4.12).
5. Operation
Caution: Did you verify whether the voltage selector is set correctly? ­If not, please refer to chapter 4.4.1! Incorrect voltage selector settings can lead to severe damage to the instrument!
The instrument may be connected to mains only with one of the power cords supplied and only to grounded sockets! The instrument may not be operated in hazardous locations where risk of explosion exists! Extreme temperature fluctuations and high air humidity (transport, storage) may cause condensation inside the instrument. In this case, wait at least two hours before switching the instru­ment on. Failure to comply with this waiting period may cause severe dam­age to the instrument!

After switching on the mains switch, the instrument will go to standby mode (mains voltage is supplied to the control unit, the control panel is, however, deactivated).
To activate the control panel, press and hold the STANDBY button for approx. 3 secs:
the control elements are activated.
Control parameters stored prior to switching the instrument off will still be available when the instrument is switched on again.
