To troubleshoot memory battery failures

Use this test when battery-backed-up memory is suspected of failing. This test separates Memory assembly failures from memory battery failures.

•Press the following keys:

[ Preset ]

[ DO PRESET ]

[ System Utility ]

[ CLOCK SETUP ] [ DATE MMDDYY ] 010101

[ ENTER ]

•Set the power switch to off ( O ), then to on ( l ).

•Press the following keys:

[ System Utility ]

[ CLOCK SETUP ] [ DATE MMDDYY ]

•If the date is 01-01-01, the battery-backed-up memory is functioning correctly. Enter the current date. Go to page 4-31,‘’To perform self tests,’’ to continue troubleshooting.

•If the date is incorrect, remove the Memory assembly.

See ‘’To remove memory’’ on page 6-13.

•Check that the voltage at TP200 is 3.5 1V.

•If the voltage is correct, the Memory assembly is probably faulty.

•If the voltage is incorrect, replace the battery (B200).

There is danger of explosion if battery is incorrectly replaced. Replace the battery with the same or an equivalent type listed on page 7-12. Discard used batteries according to the battery manufacturer’s instructions.
