illuminator switched on. The brightness of the pilot lamp corresponds to the illumination intensity
adjusted.
The Primo Star iLED microscope with reflected-light fluorescence illuminator is provided with
an interlock function, which causes the built-in LED of the reflected-light illuminator to be
switched off as soon as the reflected-light illuminator is turned with regard to the stand or
detached.

Start-Up and Operation
Operation with battery supply unit:
When connecting the battery supply unit to a
power outlet via the plug-in power unit of the
microscope, the green power-on light Ready
(Fig. 12/2) is on. The batteries are charged
automatically.
The yellow charge indicator lamp Chrg (Fig. 12/3)
lights as long as the charging process continues
and goes out as soon as charging has been
finished.
While charging is going on, the microscope can be
used without any restriction. It is provided with
voltage through the supply line.
If power supply to the supply line is interrupted or
in case of power failure, the battery supply unit will
automatically switch over to battery power. The
power-on light Ready goes out.
Depending on the capacity of the batteries used,
the microscope can be operated about 6 to 8
hours with battery power.
If the battery charge status has reached its critical
value, the battery supply unit will switch off power
supply to the microscope. In order to go on
working and to charge the batteries, the unit must
be connected to the supply line. Shortly before
automatic disconnection of the rechargeable
battery package (exhaustive discharge protection)
the light begins to flash - now, at the latest, the
battery package should be recharged at the supply
line.
