Speaker
The internal speaker supplies audible verification signals normally used by the Window’s CE
operating system. The speaker is located on the front of the HX2, 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+Up Arrow and Blue+Down Arrow keys on the Alpha Mode 3 Tap keypad
• Orange+Diamond 1+Up Arrow and Orange+Diamond 1+Down Arrow keys on the
Dual Alpha and Triple Tap keypads.
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 HX2 Battery”
accessory cable.
