Aura and Chroma mounting position. The ESL should be mounted to the shelf edge using shelf rail strip. Suitable shelf rail strip is available via one of Displaydatas Fixtures & Fittings partners. The ESL should not be mounted directly against a metal surface. metal objects can interfere with the operation of the ESLs RF. Aura and Chroma fixing angle. The Aura and Chroma range of Electronic Shelf Labels are based on EInk display technology which has a viewing angle near to 180 degrees.

controlled fridges operated below 10 degC) that the labels are allowed to reach thermal equilibrium before sending images. Failure to wait for thermal equilibrium may result in a display where the text/graphics will be hard, if not impossible, to read. Often this situation occurs when the ESLs are first deployed. When ESLs are first deployed it is common practice to configure the units at normal room temperature (~25 degC) and then place them into the chiller unit whose ambient temperature of 10 degC. In this case it is extremely important that the labels are allowed time to thermally stabilise at the cooler temperature of the chiller before any image updates are carried out. We recommend that a minimum of 45 mins is allowed for the labels to reach thermal equilibrium before sending images to the labels. Please note that the same thermal equilibrium time applies to moving a label from a Chiller/Freezer into a normal ambient temperature zone. 3 Damaged Equipment When correctly installed our ESLs are designed to be robust and provide a long service life. Should damage occur to the products mechanics, which gives rise to exposed sharp edges or leaves the batteries exposed, the equipment should be removed from service immediately.

(1)

(2) This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. 4.2 FCC Radiation Exposure Statement The radiated power of this product is below FCC radio exposure limits. Although the product is a fixed installation, it is possible, as the product is fixed to the edge of a retail shelf, that a persons body may come in contact with the device, but only momentarily. Therefore, normal radiation exposure is assumed to be from momentary contact. As contact is possible, the product has been assessed according to RF exposure procedures and equipment authorization policies for mobile and portable devices. The assessment shows the product to be complaint with FCC RF exposure limits under portable exposure conditions when installed, .i.e., antennas that are within 20 cm of a persons body. 4.3 Industry Canada Warning Statements English 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 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. French Conformment la rglementation dIndustrie Canada, le prsent metteur radio peut fonctionner avec une antenne dun type et dun gain maximal (ou infrieur) approuv pour lmetteur par Industrie Canada.

Le prsent appareil est conforme aux CNR dIndustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes : (1) lappareil ne doit pas produire de brouillage, et (2) lutilisateur de lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement. 4.4 ISED Radiation Exposure Statement The radiated power of this product is below ISED radio exposure limits. Although the product is a fixed installation, it is possible, as the product is fixed to the edge of a retail shelf, that a persons body may come in contact with the device, but only momentarily. Therefore, normal RF exposure is assumed to be from momentary contact. As direct contact is possible the product has been assessed according to RF exposure procedures and equipment authorization policies for mobile and portable devices. The assessment shows the product to be complaint with ISED RF exposure limits under portable exposure conditions when installed, .i.e., antennas that are within 20 cm of a persons body. 4.5 Mexico IFETEL Warning Statement De acuerdo con la NOM-121-SCT1, seccin 4.6.2 La operacin de este equipo est sujeta a las siguientes dos condiciones: (1) es posible que este equipo o dispositivo no cause interferencia perjudicial y (2) este equipo o dispositivo debe aceptar cualquier interferencia, incluyendo la que pueda causar su operacin no deseada.
