Programming Procedure 1. Press F6 to key up the radio. (The radio’s RF output must be
terminated into a 50 ohm load.)
2. While transmitting, measure the current drain on the first test
frequency.
3. Press F6 to de-key the radio.
4. Use the Tab key to move to the next frequency point and measure
the current again.
Repeat the above steps for each frequency.
5. Select the frequency which has the highest current reading using
the Tab key.
6. While transmitting, use the UP/DOWN arrow keys to adjust the
Transmit Current Limit according to instructions in the Radio
Service Manual. This procedure needs to be performed only on a single
frequency since all other frequencies will be adjusted automatically.
7. Press F8 to save the new values.
Function Key Descriptions
F6 - TOGGLE PTT Alternately keys and de-keys the radio being serviced.
Note: All new softpot values will be updated with values
programmed into the radio.
F8 - PROGRAM VALUE Programs the selected value into the radio.
Field Definitions
New Softpot Value This is the current limit softpot which limits the amount of transmit
current drain at any frequency across the band. It should be tuned at
the test frequency resulting in the highest current at rated output
power for optimal performance. Therefore, output power should be
tuned first. The status bar shows the current setting in relation to the
minimum and maximum settings.
