will display a blinking field, "TRANSMITTER TIMEOUT", for a short

period of time.

In addition to entering a value from the keyboard, there are key

actions available as described below:

<+> Increments the field by 1 and writes the new value to

the radio if the transmitter is on.

<-> Same as <+> only it decrements.

↑↓→← Arrow keys move the cursor between fields on the

screen.

From Figure 6:

(1) This is a numeric field that is used to align the data modulation level.

This field will accept any hex value from 00 - 3F and any decimal

value from 0 - 63, depending on the current state of the screen

(Hexadecimal or decimal) displays. The bar indicator changes with

and provides a direct representation of the value of this field.

Data Modulation Settings

1. From the "Data Modulation" window and with Low Frequency

highlighted, press F4 Tx On to key the transmitter. The radio will

begin transmitting random 9600 baud data.

2. Measure the data deviation. The Modulation Monitor should be set

for 15 kHz low pass filter and no high pass filter.

3. Increment or decrement the current value (Hex or Decimal) until the

specified window for data deviation is reached. See Table 5.

NOTE

The personality map has data deviation bytes reserved for TX

LOW TALKAROUND, TX MID TALKAROUND and TX

HIGH TALKAROUND. These EEPROMS locations are pres-

ently not used and do not have to be programmed.
