connector. Pin 1 of the Pop-port
When the mobile terminal is connected to a desktop charger (e.g., DCV-15), it charges in
the same manner as it does with the charger connector.
Figure 20 shows the actual charging sequence. The channels on the diagram are:
• CH1 = Charging current across the .22 Ohm (R200) resistor on UEMEK
• CH2 = Charger voltage measure at V100
• CH3 = Battery voltage measure at R200
• CH4 = PURX
In Channel 4, PURX is released, which this indicates when the mobile terminal operation
goes from reset mode to power-on mode.
