To turn on the receiver only, in any mode

To turn on the receiver only, use the "Main Mode" dialog box as shown previously, high-
light "RX". In the "band" field, choose "Cell CDMA" or "PCS CDMA"

To verify a single, manual tuning

Open the "RF Tuning" dialog box, shown below. The tuning descriptions at the beginning
of this document describe the tuning and tell you what you need to enter, if anything,
and what values will be returned to you from the phone, if any.
According to these descriptions, choose "self tuning" for self tunings, and "RF Tuning" for
the others. Choose the appropriate test from the "tuning names" list. Values that you
must enter are entered in the "values" dialog box. If more than one value is entered,
enter a delay time in seconds in the "delay" box. This is the delay between applications of
the multiple values entered. Three seconds is sufficient for all tests to run, however in
certain cases you may want to increase the delay in order to closely observe the phone's
behavior during the tuning.
Any data returned from the phone is displayed on the status line, the box at the bottom
which in the figure below says "8 tuning, 7 self-tune Ids configured". If no tuning value
is returned, this line will indicate if the tuning was successful or not. To begin a tuning,
click the Tune button.

To adjust PDM values of AGCs and AFC

In the "PDM" dialog box, which follows, are several sliders, one each for each of the AGCs
and the AFC. Drag the slider pointer with your mouse to the value that you want to set.
The values are in decimal. Then click Set button. Alternatively, you can click the up and
down arrows next to the value fields below the sliders, which will increase or decrease
the value one step at a time. If you do this, you do not have to click Set.
