Motorola I580 service manual Self-Test Procedures, Voltage Recognition Test

BASIC LEVEL CHECKS AND SELF TESTS: Self-Test Procedures

5.Scroll down on the GPS menu until the “POSITION” option is selected.

6.Press SELECT. The unit will display a “Position” information sheet.

7.Press RFRSH. The unit will respond with “Scanning for Satellites” or “Satellite Data Is Outdated, Continue?” depending upon whether the GPS Almanac is up-to-date or not.

8.If the unit responds with “Satellite Data is Outdated, Continue?” press YES, otherwise, no action is required. The unit is searching for satellites. Once it has obtained a position fix, the unit will display the “Position” information sheet again. This could take as long as 10 minutes.

FCAUTION: The unit must be held in a fixed position during the time that it is searching for satellites.

9.Scroll down until the position coordinates are displayed. Compare these position coordinates to a known good i580 unit or a commercial GPS receiver. If a commercial GPS receiver is used, the coordinates must be displayed according to the WGS84 standard

5.5.6Voltage Recognition Test

Use this test to check the voltage-recognition circuit in the unit. To accomplish this test, the unit must first be registered on an iDEN system.

Compare the readings on the unit under test with the readings on a reference unit.

The Voltage Recognition test time is approximately 4 minutes:

1.Perform the Battery Connections test.

2.Power up the unit with a fully charged battery that is known to be in good working order. Three voltage bars (4 Vdc) should appear on the Battery Strength icon.

Note that:

0 bars ≅ 0–10% of full charge

1 bar ≅ 11-34% of full charge

2 bars ≅ 35-64% of full charge

3 bars ≅ 65-100% of full charge

3.Complete a Direct Call and monitor the Battery Strength icon while the Push- to-Talk (PTT) button is pressed.

4.Power down the unit.

If this test is successful, place the unit’s battery in the reference unit and re-run the test.

5.6Self-Test Procedures

An i580 unit allows you to conduct automatic self tests to ensure that it is working properly. Self- test procedures include gathering information from the unit’s displays and testing the functionality of basic components. These procedures usually do not require test equipment other than a reference SIM card.
