Section 2
DS-400 PROGRAMMING
Programming the DS-400 synchronizes the radio frequency to the frequency displayed on the 400. The DS-400 is programmed by setting the rocker switch actuators to either the ON or the OFF position. ON and OFF markings are located on the right end of the programming switch when facing the displays.
The direction which the radio will scan is determined by jumpers J1 and J2. Should the program code call for a reversed scan direction, rewire jumpers J1 and J2 as shown in Fig. 21.
The 400 is shipped
from the factory preprogrammed for a Code 6 in a normal scan direction.
EXAMPLE: To program the DS-400 for a Code 6, set switches 3, 7, and 9
to the ON position leaving switches 1, 2, 4, 5, 6 and 8 in the OFF position.
The 400 is now set at a program code 6. Keep in mind that power must reset
for any changes in the program code to take effect. Once the program switches
are set, avoid bumping the switch, especially when reassembling the 400,
as this could change the position of the rocker switch.
Fig. 21 - DS-400 shown is reversed scan direction
NOTE: When working with jumpers J1 and J2, use caution not to damage the PC board.
To program the DS-400, first look up the radio in the applications chart and make note of the program code. Turn to the program chart; find the proper code and begin programming.
After programming is complete, refer to the preliminary performance test.
