Dear customer!
Congratulations for acquiring our new OT-lamp MACH M5.
The MachVISION optical system provides an illuminated field with improved contrast and
excellent homogenity. Combined with the Duo-Focus feature this offers a unique possibility
for adaptation to the wound area.
With this lighting system you profit from a whole range of new developments, based on 50
years of experience in the production of operating and doctor’s lights.
The lighting system is characterised by a previously unreceivable general colour rendition
value of Ra = 96. In other words, the colours are reproduced naturally and in high con-
trast. The wound area is shown in a comfortable light.
The different reds of a wound area can now be recognised very precisely. For the doctor or
surgeon this means a considerable improvement in the recognition of details in the wound
area.
The R96 lighting system uses computer-optimised cold-light filters that reduce both the un-
wanted build-up of heat in the head area and the heat radiated on the illuminated
wound area to a minimum.
Pay attention to the special mounting instructions for ceiling lamps.
All information quoted here relates only to the illuminants. Details of ceiling or wall installation
can be found in the mounting instructions.

1. Safety instructions
Pay attention to the instructions for use when handling the lamp.
WARNING:
This device has not been designed for use in potentially explosive areas.
According to the Medical Device Regulation the lamp is classified under class I.
Store the OT-lamp in its package for at least 24 hours in the respective room before
mounting, in order to equal temperature differences.
Please read the instructions for use carefully to make the most of your lighting
system and to avoid any damages to the device.
The lamps may only be repaired and special assembly work may only be carried
out on the reflector or sockets by ourselves or a company that has been expressly
authorised by us.
The manufacturer can only be made responsible for the safety of the lamp if re-
pairs and alterations are carried out by the manufacturer himself or a company that
guarantees to observe the safety regulations.
The manufacturer cannot be made liable for personal or material damages if the
lamp is operated inexpediently or incorrectly or used for purposes other than
those for which it is intended.
The lamp is to be dismantled from the spring arm in reverse order to its assembly.
This may only be carried out after the spring arm has been adjusted in height at
horizontal position since the arm is under spring tension and can bounce up.
Make sure that the lamp is in perfect working order before every use.
Attention, external transformer!
The lamp works only with an external transformer 300VA.
The external transformer (Order No. 6701 0208) must be tested and validated ac-
cording to IEC 60601-1.
If the external transformer is not tested and validated according to IEC 60601-1, it
is not allowed to use it with Dr. Mach OT-lamps.

2. Operating the lamp MACH M5
2.1 Brief description of the lamp
The OT-lamp MACH M5 is available in following versions:
- Standard OT-lamp (F) with merging of light fields
- Duo-Focus OT-lamp (DF) with merging of light fields and focusing
- F- or DF- lamps with light intensity control (/H)
2.1.1 Merging of light fields
(F- model)
The F-model offers light field adjustment by
merging the individual light fields of each
reflector by swiveling them.
NOTE: This feature is activated by turning the
sterilisable handle.
2.1.2 Focusing (DF- model)
The DF-model offers a second additional fa-
cility to further adjust the illuminated field to an
extra small or extra large size, depending on
the specific requirements, by focusing
through moving the bulbs up or down.
NOTE: This feature is activated by turning the
ring at the top of the sterilisable handle.
2.1.3 Light intensity control (/H- model)
The OT-lamp models offer an optional feature, the light intensity control.
You can adjust the light intensity between 50% and 100%; according to your requirements.

2.2 Turning the lamp ON/OFF
The F- and DF-models are switched ON/OFF at the
main switch of the OT or at the ON/OFF switch at the
cardan bow (if ordered).
The F/H and DF/H models are switched ON/OFF
with the touch-button 1 at the key-pad of the lamp.
2.3 Adjusting the illuminated area by
merging the light fields
(for F- and F/H-models)
All F and F/H lamp models offer the feature of “merg-
ing the light fields”. This feature is activated by turn-
ing the sterilisable handle 2.
Remark:
The ring 3 has no function here.
2.4 Adjusting the illuminated area by
merging the light fields and
focusing – Duo-Focus system
(for DF- and DF/H-models)
DF- and DF/H-models also have a “focusing” func-
tion (Duo-Focus).
The combination of merging the light fields and focus-
ing (Duo-Focus system) enables the ideal adjust-
ment of the light field to the wound area in a range
from 8cm to 35cm diameter. Such a large range of
adjustment is not possible with conventional tech-
nique.
To activate the focusing function turn the adjusting
ring 3 on the handle, or – if the lamp is equipped with
a keypad at the cardan bow (for DF/H-models) –
press touch buttons 5 and 6.
Press touch button 5 to expand the focus and touch
button 6 to bundle the light to a minimum area. The
current focused diameter is shown in the LED-
display 4.

2.5 Overview of the lamp functions
Merging of light fields and focusing
Merging the individual light fields of each reflector
is done by swivelling the reflectors. The light fields
overlap.
This feature is activated by turning the sterilizable
handle (1).
Focusing is done by moving the bulbs inside the re-
flectors up or down. This way you can further adjust
the illuminated field to an extra small or extra large
size, depending on the specific requirements.
This feature is activated by turning the ring (2) at the
top of the sterilisable handle.

Handle (1)
Always activate merging of light fields first by turning the handle (1), then activate fo-
cusing when necessary by turning the ring (2).

2.6 Adjusting the light intensity
(for F/H- and DF/H-models only)
Select the desired light intensity before the opera-
tion.
At these models the adjustment is done by the key-
pad at the cardanic bow. The intensity can be ad-
justed continuosly between 50% and 100%.
Press push button 2 to increase the light intensity
and press push button 3 to reduce the light inten-
sity.
The set light intensity is shown by LED-display 1.
For other light models we recommend a dimmer in
the supply line.
