For the later adjustment of the camera stand on the dental light a cross of adhesive tape is stuck on the camera plate of the stand, so that all free ends of the tape exceed at least one centimeter over the stand ´s baseplate.
|
|
|
With a cement spatula a thin layer Hylosil® silicone (or Impregum®) is painted on the surface of the stand baseplate. For dental lights with a relief on their front side (e.g. Siemens M1, Sirona E, Pelton Crane etc.) the silicone layer must be somewhat thicker.
The stand fed with silicone adhesive is put on the center of the light front and pressed on slightly, until some silicone outpours the baseplate at the edges.
|
|
|
It is important to fix the stand in the correct position, so that the locking screws are well attainable afterwards. For right handed persons the screws should show to the right and upward sides (see image). Alternatively the screws can show upward V-shaped. (both views standing in front of the light)
|
 |
|
Now the ends of the adhesive tapes are fixed at the light and the light screen is turned upward. The curing of the silicone takes about 2-12 hours depending upon the thickness of the silicone joint (the thicker the joint, the longer the hardening by precipitation phase). The hardening by precipitation can be accelerated however by warmth. For this reason the light should remain switched on for 2-3 hours.

Laying of the camera cable
|
|
With its diameter of only 5 mm the camera cable can be laid into the tubing linkage of your dental light (the maximum diameter of the cable plug is 12 mm).
Please notice
For laying the camera cable into the inner tube of the dental light one has to drill a small hole into the front side of the dental light tube (often plastic parts). This bore hole will lead your dental light to lose its registration and warranty (medical products law). We leave it up to you to drill this hole by yourself or have a technician from your dental supplier drill this hole and lay the cable for you. A more comfortable, but less attractive way to lay the camera cable is through the use of cable clamps, cable canals or adhesive tape stuck to the outside of the dental light tubes.
|
|
Important:
In order to ensure the full mobility of the light head, a cable reserve must be present. The best way to test the length of the necessary cable reserve is to attach the camera to the stand, connect the cable plug to the camera socket and hold the camera cable to that point, where the cable is to be laid into the light tubing. Now move the light head to any possible direction. The cable should not be strained in any position or be in contact to hot surfaces of the dental light.
Note:
1. The camera cable may be broken when squeezed or be laid in to close bends.
2. Do not lay any excess camera cable in bends, because this might induce electric interferences (electric inductor coil !)

Connecting the monitor
|
|
The plug of the camera cable is connected with the camera cable socket in the connection box.
Simply latch the cable plug (possible in one position only!) into the socket. To loosen the plug just pull out the high-grade steel ring.
Important
Never remove the cable by pulling the black rubber part of it !
|
|
|
From the connection box the video cable leads to the video-in and the audio cable leads to the audio-in of the monitor. These two cables must possess so-called RCA plugs.
Professional monitors have so-called BNC sockets. In this case you need a BNC-RCA adapter.
|
 |
|
Most TV devices have so-called Scart connectors. In order to attach the camera to ordinary TV equipment, you need a Scart adapter, which has RCA sockets. LCD monitors, which are suitable for video and/or TV, often possess Scart and RCA sockets.
|
|
Regarding the monitor
Unfortunately the image quality of most LCD or plasma monitors yet cannot be compared to the image quality of a professional broadcast CRT monitor (CRT = cathode ray tube = picture tube). That is not at resolution lacking, but of the weak contrast ratio of the LCD or plasma monitors. Nevertheless, if you want to use a LCD monitor in your office, the contrast ratio of the monitor should be at least 1.000: 1.
Right now, there are monitors with contrast ratios from 400:1 up to 50.000:1 on the market and the technology of flat monitors is advancing very fast. |

Attachment of the camera
|
Once the monitor is connected to the connection box the camera can be attached on the dental light.
First you should plug the cable plug into the socket of the camera housing. Since this is possible in one position only, you should turn camera and cable plug somewhat against each other until the plug engages.
|
|
Now the camera with the groove on its rear side can be slided over the disk of the miniature stand.
While sliding the camera over the disk of the miniature camera stand you should secure the stand from the bottom with the index finger of your left hand.
Now you can connect the connection box to the power supply and switch the monitor on.

Adjustment of the camera
|
|
The optic axis of the camera lens has to be aligned to the central beam of the dental light.
For this reason stick one of the test mouth labels on the neck restraint of your dental chair. Turn the dental light on and direct the beam of light of the dental light towards the test mouth. |
 |
|
Having guided the camera with the left hand so that the test mouth simultanueously appears in the center of the beam of light and the monitor screen, the right hand tightens the locking screws of the ball joint with the enclosed allen screw driver (this explanation is for right handed dentists only)
|
 |
|
The test mouth should be visible something above the center of the beam of light . Thus preventing dazzling of your patients later. Shake the camera slightly as to make a check. The monitor image always should remain in the centre of the beam of light of the dental light !

Finished !

By the way
The camera is appropriate for continuous operation. With a power consumption of less than one Watt you need not constantly separate the camera from the power supply. It is sufficient switching off the connection box in the evening after the work.
