This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. IMPORTANT NOTE: Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: — Reorient or relocate the receiving antenna. — Increase the separation between the equipment and receiver. — Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. — Consult the dealer or an experienced radio/TV technician for help. FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. If necessary, you may reach us to clarify on this matter.

All rights reservedUser manual ver 1.1 Page 4 Introduction This multi function device is powered by any CE or UL certified 5Vdc powerbank for low load supply. A powerbank with at least 4400 mAh rating on full charge can operate the device for at least 12 hours or more on a continuous basis. Its UV resistant casing is designed to withstand the UV whitening effects on its enclosure. It is water resistant from light rain but not waterproof. It is NOT designed for use as a permanent outdoor installation. All data is transmitted wirelessly via Espressif ESP32 microprocessor module to any compatible receiver e.g. mobile app etc via radio transmission in the 2.4GHz covering the Bluetooth and wifi frequency range. Its features include header board add-on e.g. SD card (optional add on), other sensors or peripheral detectors via inter-integrated circuit interface (I2C) or serial (I2S) interfaces, and optional universal asynchronous receiver-transmitter (UART) communication to allow on board programming of the microprocessor unit. For purpose of CE and FCC certification, we have a photo diode sensor connected as an integrated device to transmit the measured irradiance value to receiver at regular intervals. 2023 © PVSure Pte Ltd. All rights reservedUser manual ver 1.1 Page 5 Important safety warning Appropriate safety cautionary notes depends on the sensor connected. Since our initial version has a photo diode sensor for use outdoors, the precautions highlight will correspond to this application. Placement of device at an unshaded location and level to the desired orientation to begin operation. Precaution #1 Work from height or rooftops. Follow your national Workplace Safety and Health (Work at Heights) Regulations. For example three-point contact when using ladder, drink lots of water when working in hot outdoor environments, wear proper sunshade or sun tan lotion etc Precaution #2 In event of weather with imminent rain and lightning, dusty or smoky environments, please refrain from operating this device until the environmental conditions improved. Continued use under such conditions will render inaccurate readings and unnecessary soiling of device sensor and its enclosure. Precaution #3 Our device circuitry is designed with low power use. Please do not modify or conduct unauthorized connections within our device. Doing so will render the warranty void and may compromise the proper functioning of the device. 2023 © PVSure Pte Ltd.
