Installing your frequency number 
indicator: 
    It’s very important that you 
display your transmitting channel 
number at all times.  To install your 
indicator, peel off the channel number’s 
backing sheet, and carefully stick the 
numbers to both sides of the number 
holder.  Now you can snap the number 
holder onto the lower portion of the 
antenna as shown in the figure – use the 
clip that fits more snugly on your 
antenna. You may wish to cut off the 
other, unused clip on the indicator.
