LR8531	For the LR8450-01

• LR8531 cannot perform measurement by itself. Memory HiLogger LR8450-01 is required separately.
• By attaching the Z3231 Wireless LAN Adapter (accessory), LR8531 can be wirelessly connected to the Memory HiLogger LR8450-01.
• The LR8450-01 and wireless modules emit radio waves. Use of radio waves is subject to licensing requirements in certain countries. Using them in a country or region other than those indicated may violate the law and may result in legal penalties.
• For the latest information about countries and regions where wireless operation is currently supported, see the "Specifications."
