2. Telephone users.

When using the telephone

to make a reservation, you are prompted for input of
information about what you wish to do. All input is
accomplished using the keypad on the telephone. The
only problem with a telephone is that most keys have
a letter and number associated with them. When the
system asks for a date or time, it is expecting an input
of numbers. A problem arises when entering an
aircraft call sign or tail number. The system does not
detect if you are entering a letter (alpha character) or
a number. Therefore, when entering an aircraft call
sign or tail number two keys are used to represent
each letter or number. When entering a number,
precede the number you wish by the number 0 (zero)
i.e., 01, 02, 03, 04, . . .. If you wish to enter a letter, first
press the key on which the letter appears and then

press 1, 2, or 3, depending upon whether the letter you
desire is the first, second, or third letter on that key.
For example, to enter the letter “N” first press the
“6” key because “N” is on that key, then press the
“2” key because the letter “N” is the second letter on
the “6” key. Since there are no keys for the letters “Q”
and “Z” e

−CVRS pretends they are on the number

“1” key. Therefore, to enter the letter “Q”, press 11,
and to enter the letter “Z” press 12.

NOTE

Users are reminded to enter the “N” character with their
tail numbers. (See TBL 4

−1−4.)
