Frequency Control Menu (key 9)
The Frequency Control menu, shown in figure 12 below, enables complete control of
each receiver channel frequency. It also allows control of the transmitter frequency with
the use of a factory password which is obtained by a special request to American Meter
Company. This menu is also used to setup and enable/disable the frequency scan option
on channel 1. The frequency for each channel is displayed in the frequency grid at the top
of the display. The top line of the grid box displays the receiver channel number, and the
bottom line of the grid box displays the frequency applied to that channel. The frequency
display is in the format ?.? which is an abbreviation of 41?.?. For example, if the
frequency display for channel 1 is displaying 3.1, then the frequency programmed into
channel 1 is 413.1. If the frequency display is flashing for any channel, then that
indicates that the channel has not accepted the programmed frequency. The
corresponding green LED on the receiver channel will also be turned off (for additional
information on receiver status indicators, refer to the Transmitter/Receiver Status
Indicator section of the manual). The flashing display is usually a result of an out of
range frequency being programmed into the channel, or because the channel is defective.
The functions available through the frequency control menu are described below:

FULL (key S): This option allows all receiver frequencies to be setup at
one time by entering a base frequency for channel 1, and then
entering an offset frequency that will be applied to each successive
channel. Once the ‘S’ key is pressed, a flashing cursor block will
appear over the digit to be changed. Simply press a key 0-9 or
press the ‘Q’ key to abandon any changes.
