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.
