region and action entry region of the display screen.
5. Press the up arrow key.
The frequency is progressively increased by an increment value of 1MHz
according to constant stepping after the up arrow is pressed once. The
increment value is displayed in the action function region.
6. Press the down arrow key.
The frequency is progressively decreased by an decreasing value of 1MHz
according to constant stepping after the down arrow is pressed once.
The RF output frequency can be adjusted by using the knob. As long as the
frequency is action function (the frequency is displayed in the action function
region), the RF output frequency can be increased or decreased by using the
knob.
7. Use the knob to adjust the frequency back to 700MHz.
2-2-1-2 Set reference frequency and frequency offset
By the following procedure, the RF output frequency is set as reference frequency.
All the other frequency parameters are relative to the reference frequency. The
frequency originally displayed on the display screen will be 0.0 Hz (the value
formed by using the frequency output by the hard function key to subtract the
reference frequency).
Although the display content is changed, the frequency
output will not be changed. All the subsequent frequency changes will be displayed
as increment value or decrement value relative to 0 Hz. The detailed operation
steps are as follows:
1. Press the PRESET key.
2. Press the FREQ hard function key, and input 700 MHz.
3. Press Freq Ref Set .
It will activate the frequency reference mode and set the current output
frequency (700MHz) as a reference value. The FREQUENCY region displays
