The Liquid Crystal Display (LCD) panel displays the frequency, time and all activated functions, including a 5-bar graph which depicts the signal level.

NOTE: It is a characteristic of LCD panels that, if subjected to cold temperatures for an extended period of time, they may take longer to illuminate than under normal conditions. In addition, the visibility of the numbers on the LCD may slightly decrease. The LCD read-out will return to normal when the temperature inside the vehicle increases to a normal range.
