Description
1. Before using this watch, the user must go to the management office of the management department to open an account and establish a file. After verifying the information is correct, it can be used; otherwise, it may cause unnecessary losses;
2. The frequency of wireless meter reading meter data is not more than 1 time/day, otherwise it will affect the service life of the battery;
3. If the water meter is submerged under water, it will greatly impair the ability of wireless transmission;
4. Record and check the reading of the mechanical water meter on a regular basis;
5, when you need to change the table, you need to log in the system to change the table operation.
