I fixed this exact problem on my TI-5006 II calculator by simply replacing a "dead" battery. Three of the four battery's were good (after cleaning their terminals) but the fourth was completely bad (i.e. read "Replace" on my Battery Tester). Other problems probably can cause this exact same error message but this cure was simple and cheap. The problem first appeared after the calculator was dropped. A sudden shock (dropping it) can cause even a good battery to fail.

Percor treadmil error codes


Precor Error 05, Key Depressed at Power Up
Probable Cause 1. A key is permanently depressed on the display.
2. An interface chip (IC) has failed in the upper PCA's keypad.
3. Liquid (cleaning solution or sweat) may be on the surface of a touch sensitive display.

Corrective Action
  1. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 is eliminated, the keypad is the cause and should be replaced.
  2. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 still appears, the upper PCA* is the cause and should be replaced. *Upper PCA's most commonly do not come with software. Remove the software (chip) from the existing upper PCA prior to replacement and install into the new upper PCA.
  3. Wipe away all liquid from the touch sensitive display. Reset power to the unit. If the Error 05 is eliminated, the liquid was the cause.

follow this steps and fix it. God bless you

The power up test sequence has detected a key in the operated condition. The power up test
sequence is performed every time the unit is turned on (powered up). This test is performed
because a permanently stuck key will inhibit the correct operation of the unit.
Possible Causes
1. A key on the display housing is permanently stuck in the operated condition.
2. One of the upper PCA's keypad interface chips has failed.
3. Liquid (perhaps perspiration) is present on the surface of a touch sensitive display.
Possible Remedies
1. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is no longer present, the keypad is the cause. The keypad is typically part of
the display housing. Replace the display housing to correct the problem.
2. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is still present, the upper PCA is the cause. Replace the upper PCA to correct
this problem. Most upper PCA's are provided without software. Therefore, the software (chip)
must be removed from the upper PCA being replaced and re-installed on the replacement
upper PCA.
3. Wipe the surface of the touch sensitive display clean of all liquid. Restart the power up
sequence, if the ERROR 5 is no longer present, the liquid was the cause.

Controls won't work. Displays message: E0 -F2-


Hi


Thanks for using FixYa. Error F2-E0 on your kitchen aid means that the keypad is shorted and to resolve this issue you’ll have to replace the electronic range control/clock (ERC). Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks
