Audio Jack

Dolphin 7900 terminals contain a 2.5mm audio jack that supports both speaker (stereo) and microphone (mono) headsets. Both microphone and speaker are located on the front panel for voice communication that is fully integrated with terminal operation.

Speaker

The Dolphin 7900 terminal has an integrated speaker that sounds audio signals as you scan bar code labels and enter data. The operating frequency range is 500Hz at 71 dB up to 80 dB. The speaker can also be used for playing sounds (e.g., WAV or MP3 files).

When used in conjunction with the microphone on the keyboard, the speaker can also be used for two-way voice communications. Both speaker and microphone are located on the front panel for voice communication that is fully integrated with terminal operation.

IrDA Port

The IrDA (Infrared Data Association) port communicates with IrDA-enabled devices such as PCs, printers, modems, or other Dolphin terminals. The maximum speed is 115kbps. For more information, see Using Infrared on page 8-5.

Scan LED

The scan LED lights red when you press the SCAN key in scanning applications.

Decode LED

The decode LED lights green when a scanned bar code is successfully decoded.

Note: Both LEDs can be programmed by various software applications.

Touch Screen Display

The 3.8” liquid crystal display (LCD) is covered with an industrial, protective touch screen lens. The video graphic array (VGA) resolution is 1/4 (240 X 320 pixel). The color LCD is 16 bits/pixel and uses active display or thin film transistor (TFT) technology.

Activate the touch screen with the stylus provided or a finger. See Using the Touch Screen on page 4-2.

By default, the display backlight illuminates when the screen is touched. See Adjusting the Backlight on page 4-3.

SCAN Key

The SCAN key is centrally located for easy access with the right or left hand. When pressed, the SCAN key activates the scanner/imager. The SCAN key also functions as an on or system wakeup control for the terminal.

Navigation Keys

The centrally-located navigation keys enable you to move and position the cursor through software programs. The up and down arrows are programmed to perform specific functions when pressed in combination with the Blue and Red modifier keys.

Recessed Keyboard

The Dolphin 7900 Series features two keyboard options: 25-key numeric and 36-key alpha keyboard. Both keyboards are recessed under the overlay for maximum durability and backlit for easy viewing in various lighting conditions. For a complete overview of each keyboard, see Using the Keyboards on page 6-1.

Microphone

Dolphin 7900 terminals feature an integrated microphone that provides audio input to the terminal when a headset is not plugged into the audio jack. When a headset is plugged in, the terminal defaults to the microphone on the headset. For more information, see Headset Control on page 7-4.
