RANGE
You can’t adjust the range when the X-28 is in the automatic mode. It is adjustable when the unit is in the manual mode, however. To do so, first put the unit in the manual mode. Now press a menu key until the “RANGE SEL” menu appears as shown at right. The current range shows at the bottom of the menu. In this case, the range is 60 feet.

To change the upper limit, first make certain the unit is in the manual mode. Next, press a menu key until the "UPPER LIMIT" menu appears. Now press the down arrow key to increase the upper limit or the up arrow key to increase it. After you've finished, wait a few
