(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:

The Zoning Administrator, in his or her discretion, may require a dimmer display for an EMC that would otherwise comply with Section 1282.07(a), if in the Administrator's opinion:

(2) It is of such intensity or brilliance as to impair the vision of a motor vehicle driver with average eyesight;
