B. Proceeding through the Test Program
When entering the test program, the following display will
appear.
01 SRAM
To select a test program number, use the [ SEL.] or
[SEL. ] buttons. After making your selection, push the
[SAVE/ENT.] button to begin the test program. It will
proceed automatically.
If the test fails, the [FAIL] message is displayed on the
LCD. To move on to another test program when the test
has failed, depress the [SHIFT] button and select the new
test program.
Exception: If test number T-11 fails, turn the power switch
off and re-enter the test program.
