System Connector Protection Test
Perform the Ohm measurements by using the DMM instrument (Fluke).
Note!
Note! Connect the Black probe to the X3000_PIN 9 (GND).
PIN_1 PIN_9 (GND) PIN_12
System Conn.
The Battery must be removed from the Phone during this test.
-Fault Trace SW
This test should be performed in 3 steps:
Step1:
Use Fault Trace SW and go to: Logic - ADC Values – Read ADC Value (Reading 1).
Step2:
This step should be made 30 seconds after Step 1.
Use Fault Trace SW and go to: Logic - ADC Values – Read ADC Value (Reading 2).
Step3:
Compare the difference between Reading 1 and Reading 2 with the reference table
below. If the Reading 1 value is between 50 and 680 go to Interval 1, if between 681
and 800 go to Interval 2, if between 801 and 880 go to Interval 3 and compare with
the Reading 2 – Reading 1 Min and Max Limits.

Note! The upper table contains the absolute limits for the readouts. The lower table
contains the allowed delta between the first and the second readout, separated in
time with 30 seconds.
Note! If the readings is out of limits then Replace C4036 (Backup Capacitor). If still

Display Filter Test
This Test must be made for all Display Filters below:
Z2500, Z2501, Z2502, Z2503, Z2504, Z2505, Z2506 and Z2507
To perform this test use:
-Digital Multimeter instrument (DMM) and Microscope
-Use the Measurement Points Drawing to find the locations of the Display Filter
components.
Display Filter Test 1:
Check if the any of the Pins: 1, 2, 3, 4, 5, 6, 7, 8 is short circuit to GND:
If Yes Replace the Faulty Display Filter Component.
If No go to Display Filter Test 2.
Display Filter Test 2:
Is the resistance max 12 Ohm between the following pins:
Pin 1 and 5
Pin 2 and 6
