Flash Programming

The “FLASH” software is the current version of the LPE-200 radio operating software. When changes and enhancements are made to the operating code, the new operating code can be “FLASHED” to the radio, upgrading the operating code without any hardware changes to the radio. Flash software is simply a computer file which is read from a disk and downloaded to the radio using the PC Programmer. The Equipment Setup shown in Figure 7 is same as for Personality Programming.

Programming Mode

The PC Programmer cannot communicate with the radio unless the radio is in the Programming Mode. To place the radio in Programming Mode:

1.Initially the radio should be OFF.

2.Press and hold the PTT, Monitor and Clear buttons.

3.Power the radio ON. Release the buttons.

4.All pixels on the display should be lit until communication with the PC begins.

BASIC TROUBLESHOOTING

The objective of this section is to guide in quickly isolating a problem to either hardware or software. Software errors and problems can usually be corrected in the field. Hardware failures are difficult to isolate and sometimes very tedious to repair without specialized tools. As stated previously, hardware repair to this radio is very limited at best and not recommended. Service Parts has set up a Repair and Return policy. Service Parts has also made provisions for Circuit Board and Module replacement as required.

This section includes a General Troubleshooting Table and Test Point Diagram for checking Nominal Transmit/Receive Levels (not recommended). Start by following Table 1 - General Troubleshooting and then use the remaining reference material as needed.
