Motorola Sse 5000 6881094c12 A Manual

							Chapter 6 Encryption
This chapter describes the encryption capability of the SSE 5000 radio.
6.1 Load an Encryption Key
To load an encryption key:
1. Refer to the key-variable loader (KVL) manual for equipment connections and setup.
2. Attach the KVL to the radio. The display shows “KEYLOAD.” All other radio functions, except 
for power down, backlight, and volume, are locked out.
3. Refer to the KVL manual for how to load the encryption keys into the radio.
4. When the key is loaded successfully, you will hear:
• On single-key radios—a short tone.
• On multikey radios—an alternating tone.
6.2 Multikey Feature
This feature allows the radio to be equipped with multiple encryption keys. The encryption keys can 
be tied (strapped), on a one-per-channel basis. It can support up to three different encryption 
algorithms simultaneously (DES, DES-XL and DES-OFB).

							Chapter 7 Disassembly/Reassembly Procedures
This chapter provides detailed procedures for disassembling/reassembling SSE 5000 radios and 
also includes preventive maintenance and handling precautions, which provide information vital to 
the successful operation and maintenance of your radio.
When performing the disassembly/reassembly procedures, refer to the exploded view (Figure 7-1 on 
page 7-3) and to the parts list (Table 7-1 on page 7-4). Items in parentheses ( ) throughout this 
chapter refer to item numbers in the exploded view and its associated parts list.
This chapter also has procedures for removing and installing the SSE 5000 radio’s standard 
accessories and changing the Volume and Channel Select knobs.
7.1 General Maintenance
In order to avoid operating outside the limits set by the FCC, we recommend that you align the 
SSE 5000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever 
comes first. Periodic visual inspection and cleaning is also recommended.
7.1.1 Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches 
are functional. A detailed inspection of the interior electronic circuitry is not needed.
7.1.2 Cleaning
The following procedures describe the recommended cleaning agents and the methods to be used 
when cleaning the external surfaces of the radio. External surfaces include the housing assembly 
and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals 
the presence of smudges, grease, and/or grime.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild 
dishwashing detergent in water.
The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled 
brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be 
used to remove the solution and dry the radio. Make sure that no water remains entrapped near the 
connectors, cracks, or crevices.The effects of certain chemicals and their vapors can have harmful results 
on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals 
should be avoided.

7-2Disassembly/Reassembly Procedures: Handling Precautions
7.2 Handling Precautions
Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices, 
are used in this family of radios. While the attributes of these devices are many, their characteristics 
make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges. 
Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special 
precautions must be taken to prevent device damage during disassembly, troubleshooting, and 
repair. Handling precautions are mandatory for this radio, and are especially important in low-
humidity conditions. DO NOT attempt to disassemble the radio without observing the following 
handling precautions.
1. Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back 
loose-hanging neckties.
3. Store and transport all static-sensitive devices in ESD-protective containers.
4. Disconnect all power from the unit before ESD-sensitive components are removed or inserted 
unless otherwise noted.
5. Use a static-safeguarded workstation, which can be accomplished through the use of an anti-
static kit (Motorola part number 0180386A82). This kit includes a wrist strap, two ground 
cords, a static-control table mat and a static-control floor mat. 
If the radio battery contact area becomes wet, dry and clean the radio battery contacts before 
attaching a battery to the radio. Otherwise, the water could short-circuit the radio.
If the radio has come into contact with water, shake the radio briskly so that any water that is trapped 
inside the speaker grille and microphone port can be removed. Otherwise, the water will decrease 
the audio quality of the radio.• The SSE 5000 radio casting has one vent port that allows for pressure 
equalization in the radio. Never poke this vent with any objects, such as 
needles, tweezers, or screwdrivers. 
• The pressure equalization vent is located on the chassis, just below the 
battery contact. Never obstruct or cover the two slots with any object, 
including a label. Ensure that no oily substances come in contact with this 
vent.
To maintain the integrity of the RF PA, never heat it above 
210°C while performing repair or rework procedures. To 
prevent overheating the RF PA during rework, use a 
ChipMaster (R1319 or R1321) top-side pre-heat set point of 
215°C and a Dragon (R1427) bottom-side pre-heat set point 
of 204°C for 1 minute before and throughout top-side heat 
application, assuming that the RF PA is removed from the 
applied heat 10 seconds after reflow occurs. (The RF PA 
temperature does not reach the ChipMaster’s internal set 
point temperature). All other parts on the transceiver board 
can be reworked with ChipMaster top-side heat alone.
