3 3.1 Operation Introduction Once you have installed and configured the CrossCheck CDPD, it is ready for operation. When power is applied, the CrossCheck CDPD operates automatically without user intervention, based on its firmware configuration. This chapter provides a basic overview of the CrossCheck CDPD’s operation, including: 3.2 • LED Indicators • GPS Receiver • CDPD Transceiver LED Indicators The CrossCheck CDPD includes two LED indicators: GPS and GSM.
Operation 3 Figure 3.1 shows the CrossCheck CDPD LED indicators. Warning: All persons must be at least 20 cm from antenna when transmitter operating to meet FCC RF exposure requirements. CDPD LED (Amber) GPS LED (Green) Figure 3.1 3.2.1 CrossCheck CDPD LED Indicators LED States The GPS and CDPD LED have three states: On, Off, and Blink. When both LED indicators are off, the CrossCheck CDPD’s power is off. When one or more LED indicators are on or blinking, the power is on. 3.2.
3 Operation The GPS LED is on for approximately 2 seconds, then blinks until the first position fix is computed. During this period, the CDPD LED blinks until the unit is established in a CDPD area, at which point the CDPD LED turns off. When a call is active, the CDPD LED stays on for the duration of the call. GPS and CDPD LED States 3.2.3 Table 3.1 identifies the GPS LED states. Table 3.1 GPS LED States (Green LED) GPS LED State Meaning On Computing GPS position fixes.
Operation 3.3 3 GPS Receiver Operation At power-up, the GPS receiver initializes with the last-known position. Using this information, the GPS receiver acquires satellite signals. • During the satellite acquisition process—which normally requires less than 2 minutes—the green GPS LED blinks. • Once three or more satellites are acquired, the GPS receiver computes positions, course, speed and time fixes, and the GPS LED remains on.
