THIS RADIO CONTAINS STATIC-SENSITIVE 
DEVICES. DO NOT OPEN THE RADIO UNLESS 
PROPERLY GROUNDED. TAKE THE FOLLOWING 
PRECAUTIONS WHEN WORKING ON THIS UNIT.

1. Store and transport all complementary metal-

oxide semiconductor (CMOS) devices in 
conductive material so that all exposed leads 
are shorted together. Do not insert CMOS 
devices into conventional plastic “snow” 
trays used for storage and transportation of 
other semiconductor devices.

2. Ground the working surface of the service 

bench to protect the CMOS device. We 
recommend using the Motorola Static 
Protection Assembly (part number 
0180386A82), which includes a wrist strap, 
two ground cords, a table mat, and a floor 
mat. 

3. Wear a conductive wrist strap in series with a 

100k resistor to ground. Replacement wrist 
straps that connect to the bench top covering 
are Motorola part number RSX-4015.

4. Do not wear nylon clothing while handling 

CMOS devices.

5. Neither insert nor remove CMOS devices 

with power applied. Check all power supplies 
that are to be used for testing CMOS devices 
to be certain that there are no voltage 
transients present.

6. When straightening CMOS pins, provide 

ground straps for apparatus used.

7. When soldering, use a grounded soldering 

iron.

8. If at all possible, handle CMOS devices by the 

package and not by the leads. Prior to 
touching the unit, touch an electrical ground 
to remove any static charge that you may 
have accumulated. The package and substrate 
may be electrically common. If so, the 
reaction of a discharge to the case would 
cause the same damage as touching the leads.
