Front panel keys enter numeric data, turn the LCD on or off and send data to a printer or computer. Two
wide keys located over the LCD can quickly be pressed without looking at the front panel to initiate
frequently used functions programmed by the user. All front panel keys provide tactile sensory feedback,
and key-press operations can be configured to generate an audible sound.
Speaker and external speaker jack outputs are provided that can be adjusted for quiet or noisy environ-
ments. Ear phones can be plugged into the external speaker jack to facilitate silent opera tion in quiet
environments.
