ACEENSEMBLECorded Telephone with TAM and WiFi Feature

Ensemble™ – User Guide (draft) 10/30/2012 Page 1 of 31 – Beta User Guide – Thank you for purchasing your new Ensemble™ from Clarity – the best amplified telephone that offers captioning service*. Please read these instructions carefully to ensure you take advantage of the complete set of rich features offered by this product. (* upon registration of your product; feature available if you have access to high speed internet service in your home; you will need an available LAN port on your router) . Ensemble™ – User Guide (draft) 10/30/2012 Page 2 of 31 Ensemble™ User Guide Package contents: • Ensemble (power supply and phone line cord connected to your unit) – larger black unit with the corded handset • Wireless Access Point (WAP) (power supply and Ethernet cable connected to your unit) – small white device • User guide Installation Your product comes completely assembled as you take it out of the box. In order to be able to take advantage of the captioning feature of your product, you need to have access to high speed internet in your home; locate the router in your home. Install WAP first – follow directions below before installing your Ensemble main unit • Locate the LAN ports on your router – you will need one open LAN port. They are typically on the back of the unit. If you have high speed wireless internet, you may have a modem that is separate from your wireless router. Refer to the instructions provided by your internet provider if you have problems locating the router LAN ports. • Plug the free end of the Ethernet cable from the provided WAP into one of the unused LAN ports on your router • Pull the ends of the power supply cord to untangle the cable • Plug the power supply for the WAP in an electrical outlet close to your router • Allow a few minutes for the WAP to start up and to talk to your router; your WAP is ready when the two blue lights and one orange light are lit and steady (not flashing). Main unit installation (Ensemble) – install after completing the WAP installation Locate an electrical outlet close to your phone outlet Pull the ends of the phone cord untangle the phone cord Plug the free end of the phone cord in your phone outlet Pull the ends of the power supply to untangle the cord Ensemble™ – User Guide (draft) 10/30/2012 Page 3 of 31 Plug the power supply in the electrical outlet close to the phone outlet Allow a few minutes for the unit to start up; you will notice a message on the screen “Please wait...” It takes several minutes for the Ensemble unit to start completely. Do not touch the screen until you see the message “Ready”; once that disappears, you are ready to start using your phone. NOTE: IMPORTANT! Use only the power adapter supplied with your unit. Using a different power supply may damage your unit and voids the warranty. NOTE: you can choose to connect your Ensemble directly to your wireless router (without using the WAP included with the Ensemble unit); the unit can connect to routers with WPA/WPA2 Personal security settings. You can do this if you know all settings of your wireless network – see Connection section. To verify that your telephone has wireless access, check the upper line on your display – you should see the wireless symbol next to the date. (in some cases, it can take several minutes for the WAP to provide the Ensemble unit with a valid IP address. This IP address is necessary to check registration, register, or make a Clear Captions call. If you encounter any problems with internet connectivity, please wait 5 minutes and try one more time.) Ensemble™ – User Guide (draft) 10/30/2012 Page 4 of 31 Registering your device with ClearCaptions™ Your device has to be registered with ClearCaptions™ in order to access the captioning feature. If you have high speed internet access and you installed your WAP, you will be prompted to register your device in order to access the captioning service. Your device displays a registration page – touch the first text box (under First name) and a keyboard will be displayed on your screen; fill out the entire page and press “Finish”; if registration was successful, you will see a message on your screen “Registration successful”. You can choose to ignore the registration page at startup, by pressing the X at the top right corner of your screen. You will not be able to use the captioning feature of this product until your device is registered with the ClearCaptions™ service. • To register at a later time, press the Settings icon, then choose the section named About Phone. • In the About Phone window you will see a section named ClearCaptions™ Device ID; you will see the Device ID of your unit, and the status registered/unregistered. • If your unit is unregistered, press the Register button in this section – and fill out the required fields in the registration page. • Press Finish when done; if the process is completed, you will see the “Registration Successful” message on your screen. • If the process did not complete, repeat the steps to register your unit. You can also set up a ClearCaptions™ account by the registering with the ClearCaptions™ service on a different device with internet access – like a computer, a smart phone, a tablet, etc.Some customers will find it easier to complete the registration on a computer with a full size keyboard. Go to www.clearcaptions.com and sign up for the service following the directions on this website. Once you have signed up, use the same email address and password used to create the ClearCaptions account to register your device; follow the steps to access the registration page on your device, and choose the Sign In button at the bottom of this page; use the information in that window to finalize the registration process.

INTERTEK TESTING SERVICES Job no: HK12100071 RF exposure - 1 of 1 For Maximum Permissible Exposure (MPE) evaluation of the base unit, the maximum power density at 20 cm from this mobile transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65. For the base unit of tested model of ENSEMBLE, the maximum field strength measured (FS) was 117.0 dBμV/m. The distance (D) between the antenna and the equipment under test (EUT) was 3 meters. And the maximum source-based time- averaging duty factor in Single operation is 100%. From these data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The radiated power = (FS*D) 2 / 30 = 150.36 mW The radiated (EIRP) source-based time-averaging output power = (150.36 * 1.000) mW = 150.36 mW The power density at 20 cm from the antenna = EIRP / 4πR 2 = 0.0299 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the base unit at least 20cm from nearby persons.”
