1. Introduction
DARAY’s X740 is a state-of-the art, cost-effective examination light for use during
medical or veterinary consultation and diagnosis. The light uses the latest LED
technology to give an intense light at the ideal colour temperature for accurate
medical diagnosis (without the need for secondary filtering) with virtually no heat.
Multiple mounting options are available.
The X740 features a high-output intensity and variable colour temperature, which is
variable via a touch panel on the side of the light head. The light operates from a
safe low voltage produced by a mains transformer, and has a swivelling, spring-
balanced arm system and a rotating head to allow accurate and stable positioning of
the light-patch.
The light comprises 3 parts: light-head and articulated arm system, power-supply
module, and the mount of choice. The rigid spring-balanced arm allows the light-
patch to be placed accurately and stably where it is needed.
All versions are delivered in special-to-type packaging which identifies on the ends of
the box the model type and serial number of the light within.
This user & installation guide contains all the information you need for installation,
operation and maintenance.

2.2 Pre-Start Checks
Please check that the power cable is without visible damage, harsh folds, knots or
cuts in the rubberised coating.
When applicable, please check that the cable is fully inserted into the power socket,
before switching the power on.
Please check that the head and all parts of the base are without visible damage.

3. Operation
3.1 Range of Motion
The full range of motion between the X740 Range varies.
This is an image depicting the range of motion on a standard wall mount fitting.

Page 9of 30
3.2 Powering On & Variable Intensity
The X740 uses a control panel on the side of the light-head to power the light on and
off, and to adjust the brightness (intensity), and colour temperature.
-Press the power button to power ON or OFF.
-Press and hold the plus or minus buttons to adjust the intensity. It takes
approximately 5 seconds to switch between the highest and lowest
settings. Release the button when at a comfortable setting for the user.
-You can also press the plus and minus buttons to fine tune the intensity.
-Repeat the above steps to adjust the colour temperature.

Page 10 of 30
3.3 Adjusting the Light Head
The X740 head is secured using an adjustment knob on the side of the arm, near the
head. This also controls the forward and backward motion of the head itself.
Loosening this thumb screw will allow you to position the light-head up or down.
NOTE: Care should be taken not to over tighten the screw.

4.1.1 Considerations
Wall Construction
Before fixing it is important to consider the strength of
the wall and the depth of the fixings used.
Use of a building engineer or structural drawings may be
required to decide on suitability.
Examinations to be
undertaken
We recommend the bracket be installed approximately
850-1100mm from the floor to the underside of the
bracket –dependent on couch height.
It may be necessary to adjust this height, if there are
specific medical procedures the light will be used for. If
in doubt consult the end user or DARAY. When installing
the bracket take consideration of where you want the
light head to sit when in its lowest position.
Locations of nearest
mains sockets
The X740 wall mounted light uses a plug-top transformer
with a DC jack connection.
Only the supplied certified power adapter should be used
with the light.
The length of this cable is approximately 1.8m so the wall
mounted light should be within 1.5m of a mains power
point.
NOTE: The following versions are not supplied with a
plug-top transformer (X740LE1 / X740LE2 / X740LE3 /
X740LE4). A separate transformer is supplied to make a
hardwired connection.

Page 13 of 30
4.1.2 X740LW - Placement and Installation
The power supply for the X740LW is a plug top transformer with a DC jack
connection, these can be inserted into any standard UK wall socket.
Please note, under no circumstances should this product be connected
directly to the Mains electrical supply, this product requires a Low
Voltage Connection only and must only be used with a Daray Certified
Power Adapter.
• Remove the light from its packaging.
• Mark on the wall the selected location for the
wall-mounting bracket, bearing in mind the final
position of the light head required to project its
light-patch where it will be needed.
We recommend 850-1100mm from the floor to
the underside of the bracket –dependent on
couch height. Ideally, the underside of the
bracket should be 150-200mm above the couch.
•Taking note of the considerations in section 4.1.1,
mount the PIVOTW2 wall bracket directly to the
wall. Use a spirit level to ensure the bracket is on a
true vertical plane.
•Once the bracket is installed, turn the
thumbscrew anti-clockwise to allow a clear path
through the hole, and then slide the light spigot
directly into the hole in the bracket. Make sure the
light is fully pushed in.
•Tighten the thumbscrew to secure the light in
position.
