In terms of user experience with the TF-2, what is recommended while waiting for the light bulbs to warm up?

Engaging with another task while waiting for the light bulbs to warm up is recommended because it enhances the overall efficiency and productivity of using the TF-2. During the warm-up time, which is necessary for the bulbs to reach their optimal functioning temperature, diverting your attention to other tasks can help maximize your time and keep workflow smooth. This approach not only prevents idleness but also helps maintain focus and utilization of available time for other important activities.

Other options may imply either premature use of the equipment before it's ready, which can lead to suboptimal performance, or checking for issues that should ideally have been addressed prior to using the equipment. Monitoring the temperature might not be necessary if the usage guidelines recommend waiting for the warm-up phase, indicating that this time should be used wisely rather than in passive observation.
