Installation and operating instructions
During installation, ensure a firm mechanical attachment of the module without vibration transmission.
For proper operation, it is necessary to use a stabilized 5V DC power supply.
After installation, adjust the focus according to the desired working distance and the size of the projected image.
During long-term operation, we recommend ensuring adequate heat dissipation according to the selected power variant.
Use the module within the specified operating temperature range.
Safety notice
Laser radiation can be dangerous to your eyesight.
Do not look directly into the output beam or at its reflection from shiny surfaces.
When integrating into a device, we recommend using appropriate protective measures corresponding to the module’s power variant.
The product is not intended for use without appropriate technical assessment in applications where failure could result in a risk to health or property.
