It is vital to comply with the instructions supplied with
Use only printers approved by Carl Zeiss Meditec.
- Use only the CD supplied by the printer manufacturer to install
the printer software.
- Consult Support.Microsoft.com before using older printers to determine whether printer drivers compatible with the
Windows®XP operating system are available and use these.
- Position the printer must always be positioned
outside the range of the patient (1.5 m from the patient’s seat at the
- The operator should not simultaneously touch the patient and metal
parts of the printer.
- If a Protection Class II printer (without protective ground terminal) is
used, make sure that a power isolation transformer (see page 17 of the IOL Master Instruction
is connected to the printer power supply cable.
- Protection Class II printers (without protective ground terminal) whose wattage
(power consumption) exceeds the permissible connected load of the power isolation
transformer may not be used.
- If a Protection Class I printer (with protective ground terminal) is
used, make sure that it is connected to its own stationary wall
socket of the room's electrical installation or that a power
isolation transformer (see page 17 of the IOL Master Instruction
Manual V.5) is connected into the printer
power line. The required isolation transformer can be obtained
from Carl Zeiss Meditec.
- The power isolation transformer may not be used for printers whose wattage

Requirements for operation
- Additional portable multiple sockets or extension cords
may not to be used.
The electrical supply used with the IOLMaster must conform to IEC 60364-7-710
guidelines. USA and Canada only: single-phase 120 V AC connections with plug
type NEMA 5-15P.
During use of the IOLMaster, do not use a cellular telephone and other devices
not complying with EMC Class B requirements, as its signals may cause the IOLMaster
to malfunction. The effect of radio signals on the IOLMaster is
dependent on various factors and is therefore not predictable. To
avoid electromagnetic interference, the IOLMaster must be installed
and operated as described in the IOL Master Instruction
Manual V.5 and using
only those components supplied by Carl Zeiss Meditec.
With the exception of compatible printer drivers, the installation of
other software onto the IOLMaster is not permitted. The IOLMaster software is
programmed to prevent external (third party) software from being installed
on the system.
- The IOL Master may only be connected to private networks that are
protected from public networks (Internet) by firewalls conforming to
the latest technical standards. Such actions will render any warranty claims
The built-in power supply unit of the IOLMaster is short-circuit-proof, and does
not contain any fuses accessible from the outside.
Provided the IOLMaster is properly used, no electrical hazards exist to
either patients or operators.
Only service technicians authorized by Carl Zeiss
Meditec may open or setup the IOLMaster.
Please take care that the following operational requirements are met
when using the IOLMaster:
Light emission from the IOLMaster
The limit values as specified for Class 1 laser devices to EN 60825-1 will
be observed if the IOLMaster is operated as intended.
Proper Shut Down Procedure
- Always enter the patient data (last and first name, date of birth) or ID
No. (depending on setting in Setup menu).
- Pull the power supply cable immediately
if damage or unspecified problems occur!
- Switch off the device as follows:
- Click on the EXIT icon on the toolbar (shown above) or <E> key..
- Confirm with OK or <ENTER>.
- When the "It's now safe to turn off" message appears, turn the
IOLMaster off by the main power switch.
The program will automatically close; the readings for the last
patient will be saved and the IOLMaster will shut down automatically
(lamp in the switch goes off).
For as long as the switch lamp is lit, internal
components are still under voltage, even after the device has been switched
off at the power switch!
All-pole disconnection of the device has not been achieved until the
switch lamp goes off. The lamp must be off before the power supply is
unplugged or the device switched off at the main room switch. Failure
to observe these instructions may result in loss of data.
To completely disconnect from the
power supply the IOLMaster must be unplugged. The power cable
should not be pulled or the main switch of the room installation
activated until the screen is blank.
The device may not be switched on again until the switch lamp goes off!
The procedure described
above does not apply in the case of breakdowns or if the
device does not respond to your input. If this occurs, switch off the
device immediately and pull the power supply plug. Label the device as
being defective and call Carl Zeiss Service.
The IOLMaster's internal control computer contains electronic components
and a lithium battery (type CR 2032). At the end of its useful life it must
