There are two ways to move to a different function screen:
• When viewing a display-only function, such as Device Status or Signal Strength,
press the left or right arrow.
• When viewing a display-and-select function, such as Channel/Freq or Data
Protocol, press the up/down arrows to display the currently selected parameter
(marked with an asterisk) in the second row. Then press either the left or right
arrow to move to a new function screen.
Note – If the currently selected parameter (shown with an asterisk) is not currently displayed
on the LCD, and the backlight is off, you have not pressed a button for more than 20 seconds,
you can scroll directly to the selected parameter by pressing the left or right arrow once. To
move to a new function screen, press the left or right arrow a second time.
To speed field configuration and to prevent the selection of unsupported radio
configurations, the user interface displays only those function settings that make sense
based on the settings chosen for previously displayed functions. What you choose for the

spacing only at 4800 bps. And because TT450S (HW) is a Trimble protocol, Trimble-
Edit configuration
The LCD display includes an Edit Config screen that indicates if configuring the radio with
the keypad is Enabled or Disabled. The current selection is displayed with an asterisk on
the second row of the Edit Config screen.
To switch the selection:
1. Press the down arrow to display the other option and then press
Enter.
You must enter a passcode, which is 369369 for all ADL radios.
2. Press the right arrow to display a 3 on the second row.
3. Press the down arrow to display a 6.
4. Press the left arrow to display a 9.
5. Repeat Step 2 through Step 4. When you see 369369 displayed on the second row of
the LCD, press
Enter; the keypad’s ability to configure the radio is changed.
You can also use the ADLCONF software to enable/disable the Edit Config function in
the radio. Select/clear the Enable check box in the Advanced menu of the Serial Interface
screen.
Scrambling
To demodulate a digital transmission, a receiver must synchronize itself with the
transmitter. This can be hard to do when the transmitter sends a long series of one’s or
a long series of zeroes. But if every nth character in the transmission were switched, a
one to a zero or a zero to a one, and if the receiver is expecting this, it can more quickly
