Voltage Recognition Test - Motorola iDEN i530 Field Service Manual

BASIC LEVEL CHECKS AND SELF TESTS: Mechanical and Electrical Checks
3. Scroll until the GPS menu option is highlighted.
4. Press SELECT.
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Outdated, Continue?"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 If the unit responds with "Satellite Data is Outdated, Continue?"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.
CAUTION: 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 i530 unit or a commercial GPS receiver. If a commercial GPS receiver is used,
the coordinates must be displayed according to the WGS84 standard.

Voltage 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.
To perform the voltage recognition test (test time approx. 4 min.):
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 (3.6 Vdc) should appear on the Battery Strength icon.
Note that:
0 bars ≅ 0–10% of full charge
1 bar ≅ 11-40% of full charge
2 bars ≅ 41-70% of full charge
3 bars ≅ 71-100% 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.
