First, turn off all of the transmitters you intend to use

with the receiver.

NavigatetotheSETUP/SCANscreenandpressthe

MENU/SELbuttontostartthescanner.Thedisplaywill

switch to the Scan Window(seeillustrationabove)and

start scanning immediately. Allow the receiver to scan

acrosstheentiretuningrangeatleastonce,thenpress

theMENU/SELbuttontostopthescanning.

Data gathered during a scan is stored until it is inten-

data will remain and subsequent scans can be made

to search for additional signals or to accumulate higher

peaks.
