It should not be mounted directly to a metal surface. 1.2 Chroma 16 mounting orientation. The label should be mounted along the shelf edge with the front bar code below the display. 1.3 Aura 21/29, Chroma 21/29/37, DD21X / DD27X / DD29X / DD37X mounting orientation. The label should be mounted with the display aligned horizontally along the shelf edge with the front bar code on the left-hand side. 1.4 Aura 42 and Chroma 42/60/74/125 mounting orientation. The label can be mounted with the display in landscape or portrait orientation using the mounting bracket available through Displaydatas Fixtures & Fittings partners. 1.5 DD42X / DD60X / DD74X mounting orientation. The label is to be mounted with the display in landscape orientation using the mounting bracket available through Displaydatas Fixtures & Fittings partners 1.6 Aura and Chroma fixing angle. The Aura and Chroma range of Electronic shelf labels are based on EPD display technology with a viewing angle close to 180degrees. This means that the overall readability of the screens is not subject to the fixing angle. The same vertical fixing angle can be used independent of shelf height. Low temperature label variant deployment It is very important to understand some basic principles with regard to the deployment of labels into a Chiller environment (temperature controlled fridges that are below 10degC). All labels will usually be configured in a normal ambient room temperature environment

(~20degC but could be as high as ~30degC). Once they have been configured onto a system, they can then be placed into a chiller unit. It is extremely important that all the labels are allowed time to thermally stabilise at the new colder temperature before any image updates are carried out. It is essential to allow 45mins for the labels to reach thermal equilibrium before sending images to the labels. 2019 Displaydata Ltd Page 2 of 6 2 Failure to wait for thermal equilibrium may result in a display where the text/graphics will be hard if not impossible to read. Please note that the same thermal equilibrium time applies to moving a label from a Chiller/Freezer into a normal ambient temperature zone. 2019 Displaydata Ltd Page 3 of 6 3 FCC Warning Statement These devices comply with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(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 Radio Equipment Canadian Warning Statements English French 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. 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. Dans le but de rduire les risques de brouillage radiolectrique lintention des autres utilisateurs, il faut choisir le type dantenne et son gain de sorte que la puissance isotrope rayonne quivalente (p.i.r.e.) ne dpasse pas lintensit ncessaire ltablissement dune communication satisfaisante. 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. 2019 Displaydata Ltd Page 4 of 6 5 Radio Equipment Mexico Regulatory 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. 6 North American approval detail Model name (HVIN) ISED/IC identity number FCC ID DD74X DD60X DD42X DD125X DD37X DD29X DD27X DD16X DD21X Chroma 16 Chroma 21 Chroma 29 Chroma 37 Chroma 42 Chroma 60 Chroma 74 Aura21 Aura29 Aura29F 8910A-1200226 VC7120-0226 8910A-1200225 VC7120-0225 8910A-1200224 VC7120-0224 8910A-1200213 VC7120-0213 8910A-1200201 VC7120-0201 8910A-1200200 VC7120-0200 8910A-1200199 VC7120-0199 8910A-1200195 VC7120-0195 8910A-1200194 VC7120-0194 8910A-1200144 VC7120-0144 8910A-1200118 VC7120-0118 8910A-1200112 VC7120-0112 8910A-1200165 VC7120-0165 8910A-1200129 VC7120-0129 8910A-1200131 VC7120-0131 8910A-1200157 VC7120-0157 8910A-1200118 VC7120-0118 8910A-1200112 VC7120-0112 8910A-1200112 VC7120-0112 2019 Displaydata Ltd Page 5 of 6 7 Battery Caution Statements 2019 Displaydata Ltd Page 6 of 6
