Checking the Installation

1. Insert the fuses into the power leads.
2. Switch on the radio to confirm that it is operational, but do not
transmit.
3. Connect an in-line power meter between the radio and the antenna.
4. Place the radio in transmit mode and measure the forward and
reflected power levels.
5. Less than 4% of the forward power should be reflected. If this is not
achieved, check the installation, including the antenna length.
6. Start reducing the length of the antenna in steps of 0.1 inches to
0.2 inches (2 to 5 mm); measure the power levels at each step.
7. Once the reflected power levels are within tolerance, make a call to
another party on the radio.
