AquaCheck (Pty) Ltd shall not be liable for any loss or damage arising from the use of any information contained in this publication, or any error or omission in such information, or any incorrect use of the product. Version 1.1 FEB 2015. 3 STATEMENT OF COMPLIANCY ELECTRO-MAGNETIC COMPLIANCE The ACPROBE-R wireless probe has been tested and found to comply with the limits for this Class digital device, pursuant to the requirements of the CE 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 instruction manual, may cause interference to other radio communications. EMC APPROVALS The ACPROBE-R, Analogue and MobiCheck versions of the AquaCheck probe have been tested and found to comply with the following EMC guidelines: IMMUNITY TESTING: IEC 61000-6-1 and IEC 61000-6-2  Electrical Fast Transients (EFT) - IEC 61000-4-4  Electrostatic Discharge (ESD) - IEC 61000-4-2  Surges - IEC 61000-4-5  Radiated Susceptibility - IEC 801 –3  Voltage Dips and Interruptions - IEC 61000-4-11  Conducted Susceptibility - IEC 61000-4-6 EMISSIONS AND HARMONICS: CISPR 11/14/15/22 IEC 61000-3-3 and IEC 61000-3-2  Radiated Emissions  Conducted Emissions  Flicker  Harmonics 4 NOTICE: Changes or modifications made to this equipment not expressly approved by AquaCheck (Pty) Ltd. could void the user's authority to operate the equipment. Use only AquaCheck (Pty) Ltd approved accessories. 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 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 This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. This radio transmitter (identify the device by certification number, or model number if Category II) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. 5 Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son numéro de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.
