NOTE
The output current is shown in large characters on the display. To increase or reduce the current
output, press “+” or “-.” The vertical bar graph at the bottom of the display indicates which of the
seven current output steps is being used. If the transmitter can supply the requested current, the
bar will turn black. If the bar does not turn black, improving the ground connections or wetting the
ground where the earth stake is positioned may help. However, it may not achieve the current setting
requested because the line's impedance is too high for this setting. If this happens, it is best to select
a lower setting with a black bar, ensuring a stable output.
The impedance of the target line will limit the current being transmitted; therefore, it is not unusual
to increase the output level but see no increase in the currently displayed. This is not a fault with the
transmitter.
The transmitter will always revert to first level output when switched on as a power-saving feature. In most circumstances, this
output level is sufficient. Increasing the output power unnecessarily will reduce battery life. All other settings remain the same as
the last setting used.
4.2 Most Used Frequencies (Frequency Selection) Feature
This feature allows the operator to choose the most used frequencies from a list of frequencies. Once these frequencies are
selected in the main menu, the user can scroll through them by pressing the “f” pushbutton. The user can add or remove
frequencies from the above list by following the below procedure. The maximum number of frequencies that can be activated in
the most used frequencies list is 12.
The advantage of this feature is the user can work with only their preferred frequencies rather than having a more extensive list
of frequencies to scroll through.
Enter the Frequency Menu:
1. Press the “i” pushbutton four to six times (based on the mode that the transmitter is in) until reaching the “Frequency menu”
sub-menu.
