Service manual

Answer: The PC interface for the PRO-93 is not available, and it will not work with any of our currently-available interfaces. While this software
is in development, we do not have a due date; however, it is currently expected to be sold under part number 940-1666. When the interface is
available, it will be listed on our website.
A cable and software which will work with the PRO-93 is available on-line through
http://www.pro93.com/. Please note: this website is not
associated with RadioShack Corporation.

Question: Between the PRO-92 and PRO-94, which has the better scanning scheme?
Answer: In our testing, we placed a PRO-94 side by side with a PRO-92 and found each radio missed a few (and only a few) hops. The missed
hops were about the same - neither radio got everything. The significant difference was that if the PRO-94 model holds on a specific ID and
misses a hop, the hop is completely missed, where the PRO-92 typically picks it back up after a second of delay. The reason for this is that the
PRO-94 scheme looks only at the data channel; if it misses the data, that transmission is completely lost. In contrast, the PRO-92 reads the
subaudible data on each transmission. If it misses the hop, it continues to check active channels and easily finds the conversation again.
While the schemes are different, we did not find that either design was significantly better than the other.

Question: How do I calculate Base Frequency? I am looking for the mathematical formula used to calculate the BASE frequency as required.
Answer: We do not have this information. If it is available to the public, you may be able to get what you want by searching the Motorola (or
applicable) patents.
