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.
