CAUTION: This repeater contains static-sensitive devices. Do not open the repeater unless you
are properly grounded. Take the following precautions when working on this unit:
are properly grounded. Take the following precautions when working on this unit:
• Store and transport all CMOS/LDMOS devices in conductive material so that all exposed
leads are shorted together. Do not insert CMOS/LDMOS devices into conventional plastic
"snow" trays used for storage and transportation of other semiconductor devices.
"snow" trays used for storage and transportation of other semiconductor devices.
• Ground the working surface of the service bench to protect the CMOS/LDMOS device. We
recommend using the Motorola Solutions Static Protection Assembly (part number
0180386A82), which includes a wrist strap, two ground cords, a table mat, and a floor mat,
ESD shoes and an ESD chair.

• 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 Solutions part number
4280385A59).

• Do not wear nylon clothing while handling CMOS/LDMOS devices.
• Do not insert or remove CMOS/LDMOS devices with power applied. Check all power
supplies used for testing CMOS/LDMOS devices to be certain that there are no voltage
transients present.
transients present.
• When straightening CMOS/LDMOS pins, provide ground straps for the apparatus used.
• When soldering, use a grounded soldering iron.
• If at all possible, handle CMOS/LDMOS 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.

Installing a Duplexer
Perform this procedure to install a duplexer into the SLR 1000 Repeater.
Prerequisites: Obtain the following:
• Duplexer kit
• Four M3 screws (obtained from the repeater package)
• T10 bit screwdriver
When and where to use:
Install a duplexer when transmitting and receiving using one antenna.
Install a duplexer when transmitting and receiving using one antenna.
Procedure:
1 Turn off power to the repeater.
2 Disassemble the repeater, as follows:
a Turn the repeater over and remove the four M4 screws using a T10 bit.
b Hold the cover onto the chassis and carefully turn the repeater over.
c Slowly remove the top cover, making sure not to damage the front panel flex cable.
3 Disconnect the following cables. See
Figure 27: SLR 1000 Repeater Front View (without top
cover) on page 74
.
a Disconnect the front panel flex cable from the front panel display board.
b Cut the tie wrap that secures the Tx and Rx cables.
c Disconnect the Rx cable from the Rx output port by gently pulling up.
d Disconnect the Tx cable from the Tx output port by gently pulling up.
