Aiming mode
This mode best applies when two barcodes are printed too close to each other. It is
necessary to take aim first to make sure the correct barcode will be scanned.
Press the scan trigger to aim at a barcode. Within one second, press the trigger again
to decode the barcode.
The scanning continues until one of the events happens:
(1) A barcode is read.
(2) The preset timeout expires.
Note: The system global variable AIMING_TIMEOUT can be used to change the default
one-second timeout interval for aiming. The unit for this variable is 5 ms.
