The Menus
Setup Mode
Entering the Setup mode allows you to change some basic functions of the Code
Tutor. To enter the Setup mode, first turn off power to the unit, then press and
hold both the Previous and Select buttons while turning power on. When
"ON-
THE-FLY SPEED"
appears, release the buttons. In the Setup mode, press Next or
Previous button to select the next or previous submenu, respectively, and press
the Select button to toggle the options within that submenu.
To exit the Setup mode, press and hold the Select button for one second.
Release the button after
"EXIT" appears to resume with normal operation.
You choose Setup options from two submenus. These are:
• On-the-Fly Speed: With this option ON, you may change the sending
speed while the Tutor is sending, as described below in the section on the
Play menus. In Setup mode, you may turn this feature OFF to avoid
accidentally changing the speed during a session.
• Play Format: This selects the order in which the character is sent to the
display and the speaker. You may choose to have the character sent to the
display first, then the speaker, or vice-versa.
Overall Speed Menu
This menu allows you to select a sending speed from 3 to 80 words per minute
(wpm). By "overall" speed, we mean the speed at which the words or groups
are sent. A "word" is defined as 50 units of time, and the word "PARIS" is
exactly 50 units in length. Therefore, if "PARIS" is sent 13 times in one minute,
the sending speed is 13 wpm.
Standard Morse code timing defines a dit as one unit of time and a dah as three
units of time. Within each character, there is one unit between elements (dits
and dahs). Three units separate characters and seven units separate words.
Farnsworth spacing (see below) will increase the amount of time between
characters and words.
When
"OVERALL SPEED" is displayed, press Select to enter the menu, then Next
will increase the overall sending speed and Previous will lower it, both in 1-
wpm increments. Once you have selected your speed, press Select again to exit
