1.3.10-9 Appropriate Use of Flash Coding

Flashing should be used when a displayed item implies an urgent need for attention or action, but not in displays requiring attention to detail or reading of text.

Additional Information:
An 'off' condition should never be used to attract attention to a message. Flashing should not be used as a means to highlight routine information. Flashing should only be used as an alerting/warning code. If used sparingly, flashing symbols are effective in calling a user's attention to displayed items of unusual significance. Flash coding generally reduces search times, especially in dense displays.
