You can adjust the amount of time spent on each channel while scanning

using the following dialog to adjust the dwell time. The value is milliseconds in the

box next to the scroll bar.

Spectrum Analysis

You can obtain a graphical display of signals in a portion of the radio

spectrum using this Scanning menu option. A spectrum analysis window is opened

when you select Scanning|Spectrum Analysis. Click on the Setup push

button to obtain the following dialog:

Type in the centre frequency you require, select a step size and mode, then

click on OK to start scanning to produce a spectrum display. The range of the

spectrum analysis is determined by the step size you choose (there are always 400

steps).

NOTE: Open the radio's squelch fully (by rotating the squelch control fully

anti-clockwise) for best results.

The signal level detected at each step is displayed in the form of a graph as

the radio scans. The range of frequencies is determined by the centre frequency and

step size you chose.

You can click on the display to measure frequencies precisely while

scanning is in progress, or you can tune the radio using the cursor once you have

stopped scanning. The following push buttons are provided:
