The scanner always monitors the priority channel even if it is in a bank that is set to closed mode (see “Changing the Open/Closed Mode” on Page 58).

CHANGING THE RECEIVE MODE

The scanner is preset to the most common AM or FM re- ceive mode for each frequency range. The preset mode is correct in most cases. However, some amateur radio transmissions and trunked systems do not operate in the preset mode. If you try to listen to a transmission when the scanner is not set to the correct receive mode, the transmission might sound weak or distorted.

If you want to listen to private line or trunking transmis- sions in closed mode, you might have to change the re- ceive mode.

To change the receive mode, repeatedly press MODE. The receive mode changes as follows:
