IntroductionWhen ordering replacement parts or equipment information, the 
complete identification number should be included. This applies to all 
components, kits, and chassis. If the component part number is not 
known, the order should include the number of the chassis or kit of 
which it is a part, and sufficient description of the desired component 
to identify  it.
Crystal and channel element orders should specify the crystal or 
channel element type number,...

MTS 2000 RadiosNOTE:The Secure Module is NOT serviceable. The 
information contained in this appendix is only 
meant to help determine whether a problem is 
due to the Secure Module or the radio itself.
IntroductionThe Secure Module is designed to digitally encrypt and decrypt voice 
data in Motorola’s MTS 2000 Series Handie-Talkie™ Portable Radios. 
The Secure Module uses a custom encryption...

Appendix A- 2SPI bus consists of five signal lines. Refer to Appendix Table 1 for the 
signal information. A communications failure between the host 
processor and the Secure Module will be indicated as an “ERROR 09/
10” message on the radio display.
