Test Mode 5.3
The Test mode can be entered, if enabled, by pressing and releasing the SCROLL key until
tESt is displayed. Press the DOWN key and tSt1 will be displayed. This test can be initiated
at this time or press the SCROLL key to advance to the desired test. Test 1, 2 and 3 are
performed as a block so the display will advance from tSt1 to tSt4.
All available test procedures are listed in TABLE 5-2 (page 49). Test 1, 2, and 3 are per-
formed on start up, periodically during Control, and on entry into the Test mode. Test 4 is
executed on entry into and periodically during the Control mode. These tests can be used as
trouble-shooting aids.
