Warm Start; Self-Test Sequence - Cannon TE-3000 Instruction & Operation Manual

2. Warm start

C. Self-test sequence
This is the abnormal start-up mode for the bath and it occurs only if the
power was previously off for a period less than about two seconds, or if a
fault was detected in the microprocessor. The display will show the
following and the lights on the bottom row of the keyboard should flash
alternating.
If this condition is ever discovered, the BATH power switch should be
turned off. After waiting several seconds, turn the BATH power switch to
the ON position and wait for the display to indicate either a warm or cold
start again. If the bath comes up in a cold start condition and starts its
normal self-test sequence, it is possible that a momentary power interrup-
tion caused the warm start condition and no further action is required. If
the bath continues to enter the warm start condition, the user should
consult CANNON
The self-test sequence is entered immediately after the TE-3000 powers
up in a cold start condition. The tests performed in sequence and the
accompanied displays are as follows:
