Installing
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.
