Note: If you are out of range when you scan a bar code, you will receive an error
beep even if you do not have the alarm set. You receive the error beep
since the data could not be communicated to the base or the host.
Alarm Sound Type
If you have set the out-of-range alarm enabled, you may change the alarm type
for the scanner or base by scanning the appropriate bar code below and then
scanning a digit (0-7) bar code and the Save bar code on the Programming Chart
inside the back cover of this manual.
Default = 0.
Set the sound type to fit your
application.
Data Accumulation Mode
Scan the bar codes below to turn data accumulation (batch) mode on and off. If
data accumulation mode is on, bar code data is stored when the scanner is out
of range of the base and transmitted once the scanner is back in range.
Beeper and LED Sequences and Their Meaning
The 3820 contains LEDs on the top of the unit to indicate its power up,
communication, and battery status. Simply stated, red LED = error; green
LED = success of any type. The unit’s audible indicators have meaning as well:
3 beeps = error; 2 beeps = menu change; 1 beep = all other successes.
The table below lists the indication and cause of the LED illumination and beeps
for the 3820.
