Power Save Circuit

Your scanner features a power save circuit that is automatically activated any time you manually select a channel or car number frequency. The power save mode works by allowing the receiver to "sleep" briefly while waiting for a call on the selected channel.

USING CTCSS

When your scanner stops on a frequency that is configured for CTCSS, it checks for a match between the transmitted CTCSS (quiet) code and the code that is stored with the channel memory. If the transmitted and stored codes match, the scanner stops on the transmission and allows the audio to pass to the speaker. If the codes do not match, the scanner resumes scan operation. If the special "search" code is in use, the scanner will instantly display any detected CTCSS mode. You can store the detected code into the channel memory by pressing ENT while the code is displayed.

PROGRAMMING

CHANNELS FOR CTCSS

CTCSS allows you to program frequencies into your scanner that are used by more than one group in your area and listen only to the group that is of interest to you by specifying the group’s specific CTCSS code. CTCSS can also help reduce instances where interfering signals cause your scanner to stop on one channel.
