Message Function
Message function is responsible for warning the user
of changing conditions which require immediate
attention. Press the
MSG smart key to view the
message. Press the MSG key again to return to the
previous function. However, if a new message occurs,
pressing
MSG will not return to the previous function
until all new messages have been viewed.
When a new message exists, the MSG annunciator
flashes on and off approximately twice per second,
until either the user views the new message, or the
condition causing the message goes away. If multiple
messages exist, the annunciator continues to flash
until all new messages have been viewed.
Most new messages continue to be relevant following
viewing of the new message, and are put into the old
message list, where they remain until the condition
causing the message goes away. Other messages are
cleared from the message list as soon as they are
viewed (they don’t become old messages). The
decision whether a new message becomes an old
message after viewing is described for each individual
case below in the List of Messages section. The
formats of all messages are the same if they are in the
new or old message list.
