Selecting Beeper Volume
The scanner emits a short beep when it successfully reads a bar code. To change the volume of the beep scan the beeper volume bar
code on
page 4-7 , or use the two-function Volume Control and Wakeup button (see Figure 1-1 on page 1-3 ) on the front of the scanner
as follows:
1. Press and hold the button for approximately five seconds. The scanner cycles through three settings (low, medium, high)
emitting a two-beep tone at each setting.
2. To select a particular setting, release the button after the desired two-beep tone is heard.
Sleep Mode
The scanner enters Sleep mode when it is inactive for a specified length of time. The scanner has two levels of sleep: laser and motor.
In laser sleep mode, after ten seconds of inactivity the laser pulses at a 50% rate, then drops to 3% after a specified time. In motor
sleep mode, the scanner turns off the motor and the laser.
To wake the scanner from sleep mode, press the Volume Control & Wakeup button (see Figure 1-1 ). In laser sleep mode, also wake
the scanner by presenting a bar code to the scanner window.
LED Definitions
The scanner also communicates via an LED (see Figure 1-1 ). Table 2-2 defines LED indications that occur during scanning.
