This includes two shorter M3x8mm (QTY2) screws for the back of the PRS-M3DT and an additional strap for securing the front of the PRS-M3DT. The strap contains pre-installed inserts (QTY 2) and pre-installed M3x16mm (QTY 2) screws (shown at right). </td><td><img src="/files/UiT90d4z6CQ2UgzDlBxP" alt="" data-size="original"></td></tr><tr><td>Step 5</td><td>Install Rear Screws Into PRS</td><td>Install the M3 x 8 mm screws (QTY 2) through the back holes of the PRS-M3DT into the drone as illustrated to secure the back of the PRS-M3DT to the top of the drone.

The PRS-M3DT will take up to three (3) seconds for the LED to turn off. Once the LED is off the PRS is safe to approach.

{% hint style="info" %}
If removing the PRS-M3DT from the DJI M3D/T, it is possible that the strap and associated hardware (QTY 2 pre-installed inserts and QTY 2 pre-installed M3x16mm screws) will become stuck in the mounting holes. If this occurs, either gently loosen the screws further or gently move the strap from side to side to relieve pressure on the ends. Do not pull excessively on the strap to try and force it out.
