Audio Output High / Low
If a higher output is required, for example in very noisy environments, the RefAudio Pro radio has an
increased output setting.
Press and hold the MODE button until the “GRP” symbol on the LCD screen is blinking. Then press
the MODE button 5 times until the symbol “UL” appears in the LCD Display. Use the
and
buttons to adjust the level to “UH” for increased output. Note. When used in the UH mode the user
may experience sound distortion or hearing damage. Ensure correct volume levels are used.

Lock Mode
The radio can be placed into lock mode if required to prevent any unwanted changes to the radio.
This can be achieved by simultaneously pressing the Mode button and the RefAudio Pro button on
the front of the radio until the letters “LC” appear on the screen. In the lock mode function only the
volume of the radio can be adjusted. If the radio is turned off the lock mode will remain until the
unlock sequence takes place. To unlock the radio repeat the locking process.
