6.5. Real Time Clock (RTC)
The Fastrack Xtend has implemented Real Time Clock for saving date and time when the Fastrack
Xtend is unplugged from the DC power supply through the DC power cable.
Table 41. Real Time Clock Specifications
Charging Time start from fully discharged to fully charged
* This RTC time period is measured when the RTC battery is fully charged before the Fastrack Xtend is
unplugged from the DC power source.
* This RTC time period is for temperature from -20C to +60C. Once the operating/storage temperature is
beyond this range, this time period is not guaranteed..
Caution: When the Fastrack Xtend is shipped out, the charging voltage of the RTC battery is not guaranteed.
Once the Fastrack Xtend is on power, the RTC battery will start charging and the RTC feature can
then be resumed.
