      (4)   The EMC shall be incorporated into a permanent sign.
      (5)   The EMC's character area shall consist of no more than 50% of the allowable sign area specified in this Code for the zoning district in which the sign is located.  EMCs on signs that are 32 square feet or less in area are exempt from this limit.

      (7)   The EMC's dwell time, defined as the interval of change between each individual message on character area, shall be at least five seconds and a change of message must be accomplished within one second.  The dwell time shall not include the one second or less to change the message.
      (8)   In the EMC's character area, the message shall remain lit and unchanged a minimum of ten seconds hold time.
      (9)   The EMC's message may scroll or travel off of the character area, subject to the following limitations:
         A.   A travelling or scrolling message may only come from one direction.

      (10)   The EMC shall not have audio output.
      (11)   The EMC shall have automatic dimming capability that automatically adjusts the brightness level of the EMC to ambient light at all times of the day and night.
      (12)   The EMC shall not exceed a maximum illumination of 5,000 nits when measured at the sign's face during daylight hours and a maximum illumination of 200 nits when measured from the sign's face between dusk to dawn.

   (c)   An EMC is exempt from the requirements of Section 1282.07(a) if it is less than eight inches of height, meets the illumination requirements set forth in Section 1282.07(a)(12), and satisfies one of the following requirements:

   (e)   The owner of any EMC programmed from the site or from a remote location shall make the computer interface that programs the EMC available to the City staff for inspection upon request.  If the EMC's computer interface is not immediately available, its owner shall cease operation until such access is provided.
   (f)   EMC sign permit applications shall include a certification from the owner or operator of the sign stating that the sign shall be operated in accordance with City Code, and that the owner or operator shall provide proof of such conformance upon request of the City.
