=======================================================
initializing your scanner
If the scanner’s display locks up or does not work properly
after you connect a power source or install batteries, you
might need to initialize it.
This procedure clears all information you stored in the
scanner’s memory. Initialize the scanner only when you
are sure the scanner is not working properly.
1. Turn off the scanner, then turn it on again. Multi-system
Trunking Scanner appears.
2. Press 0 while Multi-system Trunking Scanner appears.
3. Press 1.
4. Press ENT. Initializing please stand by. appears for about 5
seconds.
Do not turn off the scanner until the initalization is
complete. When the initialization is complete, M000
appears on the top line of the display. Bank 0 Ch 00
appears on the third line.
=======================================================

If that doesn't remove the "Programmed by Scancat.... etc"

Connect the cable to computer and radio and use "Program entire (scanner)"
on the ''Program Radio'' window, but as soon as the programming "starts",
just pull out the cable from the scanner, and then it will initialize
and everything will be "gone"
