Audio Support
Speaker
The internal speaker supplies audible verification signals normally used by the Windows CE operating system. The
speaker is located on the front of the HX3, above the [ 2 ] key. The mobile device emits a Sound Pressure Level
(loudness) of at least 102 dB measured as follows:
Frequency: 2650 + 100 Hz
Distance: 10 cm on axis in front of Speaker opening in front of unit.
• Duration : Continuous 2650 Hz tone.
• The default is 1 beep for a good scan and 2 beeps for a bad scan.
• Volume Control
• Volume control is managed by a Windows CE control panel applet, an API and key sequences. To adjust speaker
volume use the Blue+White (Volume Up) and Blue+Green (Volume Down) buttons.
Volume control is covered in greater detail later in this guide.
Voice
All Microsoft-supplied audio codecs are included in the OS image. The hardware codecs, the input and output analog
voice circuitry and the system design are designed to support voice applications using a headset connected to the
"Tethered Headset/Microphone and HX3 Battery" accessory cable.
