• The PA output level can be adjusted using the rotary volume encoder (1).
• With radio power off, the radio will wake up when PA mic is keyed to make an
announcement. Please note that it will take a few seconds before the radio “wakes up”
and PA is active. Radio will return to the off state when the PA mic is released.
Liquid Crystal Display (LCD)
The current frequency and activated functions are shown on the LCD panel (21).
NOTE: LCD panels may take longer to respond when subjected to cold temperatures for
an extended period of time. In addition, the visibility of the characters on the LCD may
decrease slightly. The LCD display will return to normal when the temperature increases
to a normal range.
