EEP-ROM

5.2.1 EEP-ROM and maintenance data
GY-HM790 is equipped with four EEP-ROMS for the purpose of data maintenance, and their contents are as per the following list.
When the circuit board or EEP-ROM is replaced, there will be no data in the EEP-ROM. When the unit is turned ON, and the SYSCON
CPU recognizes that there is no data in the EEP-ROM, it automatically writes initial data into the EEP-ROM to initialize it.
The memory data shown in the table below will all be reset to the default settings. It is necessary to perform necessary adjustments
and settings again.
