Operational Details

The RF Laser:

1.chirps on a "good read" or successful scan while turning off the scanner beam, and

2.beeps loudly when it gets the acknowledgement back from the Base Station that it has received the data.

The yellow light on the back of the scanner indicates that it is transmitting. You will see up to four transmission attempts before the unit goes to sleep and waits for you to pull the trigger again. The green light indicates that it has received the acknowledgement from the Base Station. After four unsuccessful tries of transmitting to the base without an acknowledgement, the scanner chirps 8 times and goes to sleep waiting on the operator to move closer to the base station and pull the trigger again for a transmission retry. After going to sleep on an unsuccessful read, when the trigger is pulled again, the scanner beam doesn't turn on for reading; instead, the unit beeps three times to indicate is re-transmitting and just transmits again. This sleep and retransmission cycle is repeated until the acknowledgement is received or the buffer is deliberately cleared. In this way, no scanned data is lost, even though you have wandered out of range of the Base Station. Until the pending data acknowledgment has been received, pulling the trigger will only retransmit and not activate the scanning laser beam for additional reading.

If you are out of range and want to clear data in the scanner's buffer waiting to be transmitted again, by pulling the trigger and holding it down for 30 seconds, the buffer will be cleared and the scanner will emit 3 low pitched beeps.

Range

The operational range of 500 feet is far greater than is practical to operate blind from the PC. However, unless the unit becomes defective, you should experience excellent transmissions in almost any environment.

Avoid locating the Base Station next to a 900 MHz phone. Raise the Base if you are having any range issues.
