Check whether the main switch is in the ON position, and the power cord is completely plugged in. Check whether the image sources resolution is set as the supported format (refer to section Input Mode, p.22). Check whether the cable is damaged or bent excessively. Unplug the power cord from the socket and plug it in again after a few seconds to reset the Signage. Note: Unplugging the power cord will not change the settings. Image is unstable. Check whether the cable is completely plugged in. The remote control does not work. Auto on/off does not work or does not function properly. Cannot control the display remotely via RS-232. Check whether there are batteries in the remote control. Check the batteries for freshness, polarity, etc. Check whether the remote is in the operation range. Bright light may interfere with the remote control. Please avoid using the remote control near special fluorescent lights or neon lights. Check whether the TIMER setting in the menu is set to OFF. Check whether the Power On Time and Power Off Time settings are set correctly. Check whether the RS-232 cable is connected properly. If you are still having trouble with your DynaScan DS Professional LCD, contact your dealer or DynaScan directly for more assistance. 28 About DSM365 DSM365 is an internal operating system as Android, which can install the applications via USB flash drive storage, SD card or Internet.

ec aration Letter ransmission System FCC ID: 2AKWYFBP205 We, Dynascan Technology Corp., would like to declare below. The module itself is supplied to specific hosts, and the ID cannot be placed due to the limitation of its own space, so it can only be placed outside the host, at the same time the user manual has an instruction guide for labeling, and it will be checked before installation. The module vendor is a specific host supplier, so when the host supplier is integrated, due to the power supply method is different, the spurious emission and output power will be verified, so apply for Class II again. In addition, this host vendor is only used for display with mobile condition (RF exposure), so MPE conditions are generally used. If host vendors have portable changes, or collocate use with the module, SAR Class II will be evaluated.

Compliance to each of the requirements is described below:

Item Modular requirement Yes No Please provide a detailed explanation if the answer is

"No."

Have its own RF shielding Have buffered modulation/data inputs (if such inputs are provided) The modular transmitter must have its own power supply regulation. Meet the antenna requirements of section 15.203 Be tested in a stand-alone configuration, i.e., the antenna, AC or The module should do the functionality testing DC power and data input/output lines must be connected to the with the DynaScan displays. module but, the module must not be inside another case during testing. Be labeled with its own FCC ID number, and if the FCC ID is not Lo, visible when the module is installed inside another device, then The FCC ID is printed on the body label of our the outside of the device into which the module is installed must products also display a label referring to the enclosed module. The modular transmitter is manufactured so that the user can not influence the operation of the transmitter that will operate outside of the scope of the requlations. Address compliance with the Commission's RF exposure limits in Sections 1.1310 and 2.1093. LMA may be granted when one or more of the requirements in the table above cannot be demonstrated. LMA will also be issued in those instances where applicants can demonstrate that they will retain control over the final installation of the device, such that compliance of the end product is assured. In such cases, an operating condition on the LMA for the module must state that the module is only approved for use when installed in devices produced by a specific manufacturer. When LMA is sought, the application for equipment certification must specifically state how control of the end product into which the module will be installed, and will be maintained, such that full compliance of the end product is always ensured. Please provide Clear and specific instructions describing the conditions, limitations and procedures for third-parties to use and/or integrate the module into a host device For non-Software Defined Radio transmitter modules where software is used to ensure compliance of the device, technical description of how such control is implemented to ensure prevention of third party modification must be provided (see KDB 594280). Note 1: Compliance of a module in its final configuration is the responsibility of the applicant. A host device will not be considered certified if the instructions regarding antenna configuration provided in the original description, of one or more separately certified modules it contains, were not followed. Example: A separately certified low-power transceiver module using Bluetooth technology which is housed in a desktop computer, laptop or peripheral does not require the overall system to be recertified, if the desktop computer, laptop or peripheral, as a stand-alone unit, complies with all applicable technical standards. signature Name & title :Asson Ko / Senior Manager Tel +886-396-0541 ext:89741 address: 6F., No. 88, Wenmao Rd., Guishan Dist., Taoyuan City 333001, Taiwan
