Up to five (5) message screens can be programmed under the message scratchpad area.
These messages may be notes that pertain to the installation or the motor or any other
information deemed pertinent by the user. In addition, these messages may be selected

to perform certain tasks. The messages may be entered from the communications ports or
through the keypad. The following procedure demonstrates the use of the message
scratchpad:

acter press the decimal key. If an incorrect character is accidentally stored,
press the decimal key enough times to scroll the cursor around to the character.

The message is now permanently stored. Press ESCAPE to cancel the altered
message.
