1. Click the Gear icon at the right of WebLink.
2. Click the Restore Default Settings button.
*This performs an initialization processing as same as a serial command <Zrd>.
In cases where a software or hardware reset is not possible, it may be necessary to reset the code reader to factory settings
by connecting the unit's DEFAULT pin to either GROUND or VIN, depending on how the INPUT COMMON pin is connected.
Resetting the code reader in this manner is functionally equivalent to sending the <Zrdall> command.
