TABLET OVERVIEW specification parameter ModelD450C1 HWversionPVT2.0  ManufacturerMason  HOW TO INSERT THE SIMCARD AND MEMORY CARD 1. Setting up SIM and SD card 1) To remove the card tray, insert the SIM eject PIN included with your device into the small hole next to the car tray 2) The SIM card tray will pop-up. Withdraw the SIM tray 3) Insert a SIM card or micro SD into the card tray with the SIM’s chip surface facing downwards 4) Insert the card tray back into your device in the correct orientation 2. Press and hold the power button during 3~5 second to turn power on . Notes: Mason is not responsible in case of damage caused by incorrect assembly or removal of cards or damage caused by using non-standard equipment. KEY FEATURES OF D450C1 Navigation bar: 1. Left button: Return to previous screen 2. Right button: Touch on to go Task manager 3. Home button: Touch on to go IDLE FCC Statement § 15.19 Labeling requirements. 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. § 15.105 Information to the user. Note: 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. § 15.21 Information to user. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. SAR Information This phone is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the United States. During SAR testing, this device was set to transmit at its highest certified power level in all tested frequency bands, and placed in positions that simulate RF exposure in usage against the head with no separation, and near the body with the separation of 10 mm. Although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. The exposure standard for wireless devices employing a unit of measurement is known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. The device is restricted to indoor use only when operating in the 5150 to 5350 MHz frequency range. - English: 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, an d (2) This device must accept any interference, including interference that may cause undesired ope ration of the device. - French: 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'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
