It is a good idea to charge them at least once a week. However, if you know that battery requires charging more or less than this please do so. It is important to ensure that the battery will last the full day so it does not affect your work.

It is important to be aware of all privacy expectations. Do not include photos of others or any sensitive or personal information.

Always make sure you are measuring in metres. If your instrument does not do so, please contact your supervisor.
