# Operation

- Protect the measuring tool and remote control against moisture and direct sunlight.

- Do not expose the measuring tool or remote control to any extreme temperatures or variations in temperature. For example, do not leave them in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool and the remote control to adjust to the ambient temperature before putting them into operation. Before continuing work with the measuring tool, always perform an accuracy check see Accuracy Check of the Measuring Tool.
  The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature.

- Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences see Accuracy Check of the Measuring Tool.
