Understanding the Terminal’s Audio Signals
The terminal and scan module have a beeper and internal speakers to sound audio
signals or beep sequences as you use the terminal. For example, you hear a low beep
tone each time you enter or scan a valid command.
You can change the beep volume to meet the needs of your working environment. When
you change the beep volume, you also change the keyclick volume. The keyclick is the
sound that you hear when you press a key on the terminal and the Keypad Clicker
command is enabled. For example, use a quiet beep in a library or a loud beep in a
manufacturing plant.
There are two ways to change the beep volume:
• Use the Backlight key (press 

) on the keypad. For help, see “Adjusting the
Screen From the Keypad” earlier in this chapter.
• Use the Beep Volume command. For help, see “Beep Volume” in Chapter 9.
The next table explains the purpose of each beep sequence you may hear.
Beep Sequence Description
Low beep You entered a valid command or the data you entered was
stored.
High beep You entered valid data, the terminal decoded a label, or the
terminal decoded the last row of a two-dimensional bar code.
Three low beeps You entered or scanned an invalid command or data.
Four low beeps When you boot the terminal, you hear four low beeps once the
power-on self test (POST) has executed successfully.
Low beep, high beep, low
beep, high beep
You hear this beep sequence when POST failed and did not
execute successfully. For help, see “Problems While
Operating the Terminal” in Chapter 6.
Click When you press a key, the terminal sounds a click. You can
disable the keyclick. For help, see “Keypad Clicker” in
Chapter 9. The terminal also clicks while you are scanning a
two-dimensional (Code 16K or Code 49) bar code label.
Low beep (every 15
seconds)
The main battery pack is low. You need to replace or
recharge the battery pack. For help, see “Learning About the
Terminal’s Batteries,” later in this chapter.
