Why MARS 400 makes a practical gift
Simple to start
One press on the power button starts the light. The R/NIR button chooses red, near-infrared or both.
Set to stop
Each session is a set 10-minute cycle, after which the light switches off by itself.
No app, no touchscreen
No app and no touchscreen: the buttons and a countdown display are on the side of the panel.
Sits on a table
MARS 400 stands on its own folding tabletop stand, so it sits on a steady table at the angle you choose.
Setting it up together
Set it up together the first time: read the manual and choose a steady table. The steps below follow the MARS 400 manual.
- Unpack the box and check that everything is there: MARS 400 with its tabletop stand, its original power accessories, protective glasses and the user manual. If anything is damaged or missing, contact Resty before the first session.
- With the power still disconnected, unfold the stand on a steady, level table and choose the angle.
- Connect the original power accessories as the manual describes.
- Press the power button to start the light, then use the R/NIR button to choose red, near-infrared or both. The R and NIR indicators show the choice, and the countdown shows the time left.
- For the first sessions, the manual suggests a distance of about 30 cm from the panel and three sessions per week, each one standard 10-minute cycle.
- When the cycle has finished, set the rear switch to O.
Before the first session, read the Use and safety section at the bottom of this page together.
