MFJ-493 Instruction Manual

Practicing With the FCC Exam Simulator
After you have practiced individual characters you can go on to practice a simulated FCC exam.
Press the FCC Exam Simulator button and begin copying.
The keyer terminal is extremely useful when practicing exams. The keyer echoes all text to the ter-
minal so you can check your copy when the test is over.
If you give tests you can save your favorite randomly generated test to an ASCII file and save it
until the next test date.
Teaching Code
Those that give practice sessions will find the MFJ-493 of great help. Practice sessions can be writ-
ten and edited, up to 4000 characters for a single memory, in a text editor and send it as ASCII to
one of the message memories. The MFJ-493 can be taken to the classroom and give several ses-
sions of practice. The code sent is always perfect and can be modified to whatever method of
teaching one prefers.
Battery Removal and installation
The lithium cell on this keyer should last 2 years or more. The battery can be tested by removing
the cover and turning the unit ON. Test the voltage of the battery from the battery (+) to the
chassis (–). The voltage tested should be over 2.7 volts or the battery should be replaced. To re-
place the battery, the unit must have power connected and be turned ON. The battery is carefully
removed and a new one carefully inserted.
