CONTROL UNIT CU458-2 Installation Instructions (Translation of the original installation instructions) CU458-2 Foreword 93728 1.0 3 Foreword Document revision history Version Date Modification, change 1.0 03/2020 First release Disclaimer and exclusion of liability DewertOkin is not responsible for damage resulting from: • failure to observe these instructions, • changes made to this product which have not been approved by DewertOkin, or • the use of replacement parts which have not been approved or manufactured by DewertOkin.  We reserve the right to make unannounced technical changes in the course of our continual product improvement process! Creation of a complete operating instruction manual for the entire end product These instructions are only intended to be used by the end-product manufacturer. They should not be given to the operator of the end product. The factual information contained within may be used as a basis when creating the end-product manual. The warning and danger notices are best suited for use in the end product's manual. However, it is not sufficient to simply follow these notices. You should also carry out an internal risk assessment for your end product. This can then be used as the basis for the safety notices in your manual. These installation instructions do not contain all information required to safely operate the end product. They only describe the installation and operation of the product as partially completed ma- chinery. The instructions are intended for the technicians responsible for manufacturing an end product and not for the operators of the end product.

These instructions are not an operating manual for the end product. These instructions will help you to minimize danger, repair costs and down times. They will also help you to increase the reliability and lifespan of the device. CAUTION The notices in these instructions must be followed! Following the guidelines during installation and connection procedures will help to minimize: •the risk of accident and injury, and •damage to the CONTROL UNIT or the end product. T hese installation instructions have been written with due care and attention. However, we cannot guarantee that the data, images and drawings are complete and correct nor do we accept any lia- bility for the information contained therein, unless required by law. 1.3 Conventions used Notices which do not relate to safety are indicated in these instructions with a symbol: Triangular notice symbol Explanations of warning notices CAUTION CAUTION indicates a hazardous situation which, if not avoided, could result in minor or moder- ate injury. N OTICE NOTICE is used to address practices which are not related to personal injury but may result in damage to the product or surroundings. Safety notices CU458-2 6 93728 1.0 2.Safety notices 2.1 Proper and intended usage The CONTROL UNIT is intended for use: •as a control unit for suitable DewertOkin drive systems, •for HOME applications (in beds, reclining chairs, etc.). CAUTION Risk of accident This CONTROL UNIT should only be used for the applications described above. Any other use is forbidden. Improper usage can lead to accidents or destruction of the unit. Such non-approved applications will lead immediately to the expiration of all guarantee and warranty claims on the part of the end-product manufacturer against the manufacturer. 2 .1.1 Improper usage Be sure to follow the notices below concerning improper usage. You should include them in your product manual in order to inform the users of your end product. The CONTROL UNIT should not be used: •in any environment where combustible or explosive gases or vapours (e.g., anaesthesiology) may be present, •in the proximity of open fires or other heat sources (such as furnaces, ovens or direct sunlight), •as a power source for toys or games, •in any application that will be cleaned with an automated washing system, •in a moist environment, or •outdoors. The CONTROL UNIT can be used by children of 8 years and older, persons with reduced physical, sensory or mental capabilities, or persons with lack of experience or knowledge when they are su- pervised or instructed concerning the safe use of the device and when they understand the result- ing risks. Do not allow children to play with this device. The cleaning and user maintenance must not be carried out by children without supervision. You should only use spare parts which have been manufactured or approved by DewertOkin. Only these parts will guarantee a sufficient level of safety. CU458-2 Safety notices 93728 1.0 7 2.2 Selection and qualification of personnel The installation of the CONTRO…

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Control Unit CU458-2 Model Name A1320 FCC ID O3YCU458-2 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 3. CALCULATION BLE: P t =-3.690dBm=0.43mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.43mW /5mm) .[√2.48(GHz)]= 0.14<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 2.4G GFSK: P t =-0.649dBm=0.86mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.86mW /5mm) .[√2.403(GHz)]= 0.27<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Note: BLE and 2.4G GFSK don't work at the same time. 4. CONCLUSION The SAR evaluation is not required.
