14.0 Battery warning 
The Q3008 biometric reader features a battery warning system to provide information 
about the status of the device and to minimise operating errors. 
The system gives adequate warning of decreasing battery capacity. This alerts you to 
the need to change the battery in plenty of time.
Battery warning:
 A time delay is added to the ‘recognise’ process. The diode flashes 
YELLOW for 10 seconds
. Once the 10 seconds have elapsed, the Q3008 biometric 
reader issues the command to open.
