o Using a scanner or an assistant at another radio, verify that you can hear, key, and speak
over the radio from both the Captain and the Co-Captain positions using the Body PTT
switches and Remote PTT switches (if installed). Verify Tx audio level. If adjustment is
necessary, refer to Appendix C for Tx modulation adjustment.
o Repeat this procedure for Radio 2 by selecting TX2 at the Panel Display.

levels.
