6.6.5. Battery Calibration
Preliminaries
There are three procedures to calibrating the battery, voltage, temperature and charging calibration. A Battery Calibration
Voltage Control Unit (BCVCU) is used to provide the necessary voltage levels for these checks. The BCVCU replaces the two
regulated power supplies and 82 Ohm resistor required to caibrate previous mobile products.
1. Connect the telephone, test battery, BCVCU and Interface Box as shown in the diagram below.
Figure 6.26: Battery calibration test conections
2. Set the Interface box to POWER ON, IGN and EXT PWR OFF.
Voltage Calibration
1. Enter Test-Set mode in Service Channel Box.

2. Press F4 and select VIEW ADC LINES.
3. Observe the ADIN1 value. This value is BAT VOLT HIGH. If this reading is outside the range 564 - 664, then there is a
fault and further investigation is required. Otherwise, record this value for later use.
