What if the catering pager is flooded?
Do you think it's discharging water? This kind of water can't be used generally, because there is a high-frequency transmitting circuit, and this part is powered by 12V. After water is injected, it can't be used normally. Even if it can be used, it will be used for a short time, and it will be completely scrapped after a long time. Suggestion: Replace the pager immediately.
