Older units have an additional part that needs to be changed. If your AD/DA converter is an 1848, you will have to upgrade to the newer 1845. The new software will not recognize the old converter. In this case, your Rang™ will have to make a trip home to Texas because it takes a special tool to remove this part. If you are handy, you can do the replacement yourself; the tool can be purchased at Radio Shack for about $7. It's called a PLCC chip puller.

To check this out, remove the 4 top & 10 bottom screws; then place the Rang™ on its face with the roller to the right and remove the bottom cover. You'll be looking at the circuit board in all its glory. The AD/DA converter, made by Analog Devices, is one of the larger parts and is the only square one. The part number information is printed on the part and reads like AD1845JP. The important piece of info is the 4 digits. If it says 1848, then it must be replaced if you want the new software.

Also, some of the early Rangs™ were sold with 1 megabyte of memory. This provides 32 seconds of recording on normal speed and 64 seconds on half speed. If you have a 1 megabyte Rang™, this is a good time to upgrade the memory to 4 megabytes as the increased sample rate of the new software will reduce the normal speed record time to 21 seconds. If your Rang™ records for longer than 40 seconds on normal speed then it has 4 megabytes of memory.
