What should you do if the device is not functional during assembly?

If the device is not functional during assembly, replacing the battery pack is a logical first step to take. A non-functional device may often be due to insufficient power, particularly if the device relies on a battery for operation. Replacing the battery pack ensures that the device has a fresh power source, eliminating the possibility that a depleted or malfunctioning battery is the root of the issue.

It is important to consider that simply increasing the power setting may not address the underlying problem, as the device may not respond at all if there is no power coming from the battery. Waiting for the device to reset might be appropriate in some situations, but in the case of failure to function upon assembly, it is more productive to address the power supply immediately. Checking for fluid leaks is also a valid diagnostic step, especially for devices that can be compromised by leakage, but it is not typically the first action to take if the device simply isn't turning on. By starting with the battery pack, you are addressing the most common cause of power failure in devices.
