2. Operating the lamp Mach 120F/120
There are two types of Mach 120F/120 -lamps
available:
• Mach 120F with focusable light field and dielec-
tric light system Ra=93
• Mach 120 with fix-focus and standard light sys-
tem Ra=86
The lamp types are equipped with an external
transformer:
• Mach 120F/120, voltage 22,8V / external trans-
former.
2.1 ON/OFF switch
The switch 37 with signal lamp at the lamp bow
turns the lamp on and off.
Because of the external transformer of the lamps,
in addition to the switch 37 a two-pole switch
ON/OFF must be provided by the customer.
2.2 Positioning
Use the handle 17/50 or the handle rail GL to posi-
tion the lamp.
There are two handle types available:
• Handle 17
The handle 17 is fixed to the handle bar 16 and
can be removed.
• Sterilizable handle 50
The sterilizable handle can be removed for ster-
ilisation. It is fixed by the couple to the handle
bar 16.
2.3 Light field adjustment
- focusing (Mach120F only)
The lamp models Mach 120F have a focusing func-
tion. That means, you can either enlarge the di-
ameter of the light field or bundle the light to a
smaller area, depending on the circumstances.
To activate the focusing function, move lever 08 at
the lamp head up and down (see figure).

- Visual inspection
- Complete check of the ceiling or wall attachment
- Changing the halogen bulbs, if necessary
- Protective conductor resistance measurement
- Leakage current measurement
- Insulation resistance measurement, if necessary
- Functional testing
- Electrical safety check
- Light intensity measurement
- Completing the test report
4.1 Adjustments at the ceiling/wall
attachment and new-type stand
♦ Adjusting the spring arm
(new-type attachment)
To adjust the spring force proceed as follows:
a) The spring arm moves down on its own:
• Pull the lamp head approx. 20°downwards until
drilled hole B lies on the upper side of the joint
between spring arm and horizontal arm and a
screw is visible in the hole.
• Insert a slotted screw driver into drilled hole B.
• Turn adjusting screw to the left (anticlockwise),
the spring force increases.
b) The spring arm moves up on its own:
• Pull the lamp head approx. 20°downwards until
drilled hole B lies on the upper side of the joint
between spring arm and horizontal arm and a
screw is visible in the hole.
• Insert a slotted screw driver into drilled hole B.
Turn adjusting screw to the right (clockwise),
the spring force decreases.
4.2 Adjustments at the lamp head
♦ Manipulating the lamp
The lamp bow 32 enables a perfect movability and
positioning of the lamps Mach 120F/120.
The brake force in the axis Ais set. It is usually not
necessary to adjust it.

4.3 Changing of spare parts
4.3.1 Changing the halogen bulbs
Dr. Mach uses special halogen bulbs as illuminants.
Only original Dr. Mach replacement bulbs may
be used.
The use of other bulbs can lead to a considerable
reduction of the light power and increase in the
thermal load.
To change the bulbs proceed as follows:
• Attention!! Turn off the lamp!
• Loosen three screws 27 at the base frame 01.
• Remove housing lower part 02 by pulling it
downwards.
Attention! If the bulb is changed immediately
after operating the lamp, some parts of the lamp
may be hot.
Do not touch the halogen bulb with naked
hands.
• Draw halogen bulb 11 (22,8-24V/50W) carefully
from its socket.
• Put in the new halogen bulb.
• Mount the housing lower part 02 in reverse order
of dismounting it.
Remark:
The halogen bulbs have a service life of approx.
1000 hours without any deterioration in their
luminosity.
4.3.2 Changing the fuses
Because of the external transformer of the Mach
120 lamps, the necessary fuses must be provided
by the customer.
Pay attention to the instructions from the local
installer.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in
which the MACH 120 / 120 F is used exceeds the applicable RF compliance level above, the MACH 120 / 120 F should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
MACH 120 / 120 F.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between
portable and mobile RF communications equipment and the MACH 120 / 120 F
The MACH 120 / 120 F is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the MACH 120 / 120 F can help prevent electromagnetic interference by maintaining a minimum distance be-
tween portable and mobile RF communications equipment (transmitters) and the MACH 120 / 120 F as recommended below, according
to the maximum output power of the communications equipment

For transmitters rated at a maximum output power not listed above the recommended separation distance d in metres (m) can
be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of
the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
