Understanding the Reader’s Audio Signals<br />

2<br />

The <strong>JANUS</strong> reader has a beeper and internal speakers to sound audio signals<br />

or beep sequences as you use the reader. For example, you will hear a low<br />

beep tone each time you enter or scan a valid command. The next table<br />

explains the purpose of each beep sequence you may hear.<br />

You can change the beep volume, frequency, and duration to meet the needs of<br />

your working environment. For example, use a quiet beep in a library, a loud<br />

beep in a manufacturing plant, or a unique beep to distinguish the reader from<br />

other devices. For help, see the beeper commands in Chapter 12,<br />

“Configuration Command Reference.”<br />

Beep Sequence Description<br />

Low beep You entered a valid command or the data you entered<br />

was stored.<br />

If the reader sounds a low beep after you insert a PC<br />

card, the reader recognized the card, but cannot read it.<br />

You need to configure the reader or format the card. For<br />

help, see Chapter 4, “Using PC Cards in the Reader.”<br />

High beep You entered valid data, the reader decoded a label, or<br />

the reader decoded the last row of a two-dimensional<br />

symbology. When you cold boot the reader, you hear a<br />

high beep once the power-on self test (POST) has<br />

executed successfully.<br />

Three low beeps You entered an invalid command or data, or the reader<br />

detected an IRL syntax error while compiling. For help,<br />

see “Running IRL Programs” in Chapter 10.<br />

“Networking or Communicating With the Reader” in<br />

Chapter 10.<br />

Three high beeps There is a configuration error or a fatal IRL error. For<br />

help, see “Running IRL Programs” in Chapter 10.<br />

Two low beeps, two<br />

The reader sounds this beep sequence whenever you<br />

update the reader’s configuration.<br />

You can begin using the card.<br />
