2. Adjusting Remote Commander For the adjustment, the adjustment data saved in the nonvolatile memory (EEPROM) must be rewritten, and for this purpose the adjusting remote commander is used. The adjusting remote commander makes two-way communication with the product using a remote control signal line (LANC). The adjusting remote commander transmits pages, addresses, and data up/down commands to the product. The product transmits pages, addresses, and data to the adjusting remote commander.
