Heine Dermaphot Information
| HEINE DERMAPHOT ATTACHMENT
Instructions for Use:
The Dermaphot Optical Module can only be used with 35 mm SLR cameras. The camera must have a manual shutter speed selector, not autofocus.
The safety, reliability and performance of the unit only be guaranteed when it is used according to the instructions for use.
Contents:- DERMAPHOT Attachment with battery box and contact disc
- Dermatoscopy oil
- 4 Alkali Manganese Cells AA-size
- Dermatoscopy book
General Instructions:
Please follow these instructions to be sure of getting perfect results with HEINE DERMAPHOT - every time. The camera viewfinder is only used to position the camera. It is not possible to diagnose in the same manner as with the DELTA 1O.
Dermatoscope:
The DERMAPHOT offers two basic kinds of photo-documentation:
1. Clinical photography with the distance ring.
2. Dermatoscopic photography with the contact dlsc using dermatoscopy oil.
We recommend that the patient's number or reference be photographed first to simplify identification of the slides. (It is better to have the slides framed after the slide number has been recorded as the number may not be visible after framing). Important note: For photos close to the eye, the patient should close his/her eyes to avoid the effects of the flash.
Film, Enlargements:
For the best colour reproduction, use only the Fuji slide film Fuji RD 135-36 ISO 100. The normal 24x36 mm slide offers 2,5x magnification of the object. A 9 x1 3 cm enlargement offers 10 x magnification, similar to the image generated by the DELTA 10.
Mounting the Adaptor Ring:
(Only necessary where the DERMAPHOT optical module was ordered without a specific adaptor.)
1. Remove the protective cap from the DERMAPHOT and screw in the T-adaptor.
2. Attach the DERMAPHOT to the camera.
3. Loosen screws and rotate the module until the press-button is vertical.
4. Re-tighten all screws.
Setting-Up:
1. Insert the 4 AA batteries into the battery compartment.
2. Where the DERMAPHOT optical module was supplied with a camera adapter, remove the protective cap and attach the module to camera.
3. Mount the battery compartment onto the flash-shoe (Press button should be located directly over the eyepiece.)
4. Set the shutter speed to the value recommended in the camera instruction manual for flash photography.
Use of the DERMAPHOT:
1. Wind on the film to the first stop and switch the camera "on".
2. Press the knob to charge the flash. The green LED flashes during charging, then stays on to indicate f fully charged. (The LED then switches off after about one minute).
3. If the contact disc is used, the skin to be photographed must be moistened with dermatoscopy oil.
4. Hold the camera in the rjght hand and the attachment in the left (the right index finger on the shutter release, the left index finger on the button.
5. Rest the contact disc or distance ring without excessive pressure on the skin.
6. If necessary, use the viewfinder to check the position. To do this, switch on the positioning light.
7. Switch off the positioning light before operating the shutter release. Failure to do so will give over- exposed slides. (The function of the flash can be seen through the transparent tell-tale cap).
8. After use, switch off the camera and wipe the contact disc clean. The DERMAPHOT attachment switches off automatically after about 1 minute.
Cleaning and Sterilization:
The contact disc and distance ring can be cleaned and sterilized by any conventional method - in most cases an alcohol wipe is sufficient. All other components can be wiped with alcohol or cleaning spirit. The transparent cap can be removed for this purpose.
Battery and bulb changing:
One set of alkali-manganese batteries will give 300 to 400 photos. The batteries should be changed when the flash takes more than 15 seconds to recharge. The bulb in the DERMAPHOT attachment is only used for a few seconds at a time and can be used for thousands of photos. To replace, simply remove the transparent cap and unscrew the bulb.
