What does a red light indicate on the TORCH during PDI?

In the context of the TORCH during PDI (Pre-Delivery Inspection), a red light serves a critical function in signaling the operational status of the device. Specifically, it indicates a low battery warning, which is crucial for ensuring the equipment is functioning optimally and ready for use.

When a red light illuminates, it alerts the user to the necessity of addressing the battery status, ensuring the device has sufficient power for operation. Monitoring the operational status through such indicators helps prevent malfunctions or failures during important tasks. In the case of the TORCH, if the red light is flashing at intervals of no more than 10 seconds, it serves as an immediate warning to recharge the device or replace the battery, thereby safeguarding the continuity of operations.

Understanding this function is essential for maintenance and effective usage during inspections, as it directly relates to the efficiency and reliability of the equipment.
