Tip:
The laser unit should be allowed sufficient time to adjust to the ambient
temperature before you start it up.
For example, when the laser is brought from an extremely hot / cold vehicle
onto the building site.
When you’re not using the laser, store it in its pouch/carrying case.
Do not store the laser in a wet pouch/carrying case.
If the pouch/carrying case gets wet, let it dry before storing the laser in it.
Do not submerge the laser.
