IMPORTANT TIP!

The Number field in the DIAL menu is different from other entry fields in the Zephyr

Xstream. It is NOT necessary to press <SEL> before entering the number to be dialed.

While we like consistency, this field is used so often, it made sense to make it easier by doing

this. It also makes operation more similar to the Zephyr classic.
