Motorola I580 service manual Mechanical and Electrical Checks, SIM Card Swap Test

BASIC LEVEL CHECKS AND SELF TESTS: Mechanical and Electrical Checks

3.Remove any dirt from the unit using a stiff, non-metallic, short-bristled brush.

4.Wipe and dry the unit with a soft, absorbent, lint-free cloth. Make sure that there are no damp spots on the connectors or in cracks and crevices.

5.5Mechanical and Electrical Checks

Before conducting more complex tests, clean and check the unit for any mechanical defects that might cause or contribute to the problem.

The following tests constitute the mechanical and electrical consistency of the unit:

•Shock and Pressure

•SIM Card Swap

•Accessory Swap

•Lockup

•Battery Connections

•GPS Receiver

•Voltage Recognition

The Shock and Pressure test time is approximately 3 minutes:

1.Power up the unit.

2.Throw the unit into the palm of your hand alternating the front, sides, and back of the unit.

Check if the unit turns off, displays “Reset,” or status LED (if so equipped) turns to red. Then, continue to the next step.

3.Apply pressure to the front, sides, and back of the unit with your thumbs. Never apply direct pressure to any display or lens area.

If unit turns off, displays “Reset,” or status LED (if so equipped) turns to red, retry this test with a battery known to be in good working condition. Verify that the contacts in the unit and on the battery are clean.

4.Start test again. If the reset/intermittent contact condition persists, power down the unit and send to your iDEN Customer Support Center.

5.5.1SIM Card Swap Test

Use this test to determine if the SIM card is defective, or if the unit is defective.

The SIM Card Swap test time is approximately 5 minutes:

1.Power off the unit, and then remove the battery.

2.Remove the SIM card from the unit.

3.Clean the SIM card, if necessary, by wiping its surfaces with a clean, static-free cloth, and then check the contact areas in the unit for foreign material, damage, or other defects.
