Installing the T2-2R, T3-3R, and T4-4R Receiver Mute Option Kits

Procedure:
1 Install the standalone GTR 8000 Base Radio and GPW 8000 Receivers according to the
processes and procedures in the Base Radio or Receiver Installation chapter.
WARNING: To guard against personal injury and/or damage to equipment, place the
base radio to Service Mode when performing service. Transmit inhibiting the base radio
within the Station Status screen in the Configuration/Service Software (CSS) also
prevents the transmitter from keying. Place the base radio back to Normal Mode when
service is complete.
NOTICE: See
example of the GTR 8000 Base Radio and GPW 8000 Receivers installed in a rack.
Leave no spaces between the devices in a rack or cabinet installation. Leave enough
space above the splitter and antenna relay tray to allow room for connecting cables.
2 If the devices are in Normal Mode, ensure that each device is placed in Service Mode, as
follows:
a Connect to the transceiver module Ethernet service port using CSS. See
Through an Ethernet Port Link on page
b From the menu, select File → Read Configuration From Device.
c From the menu, select Service → Test And Measurement Screen.
d Click Change to Service Mode.
e At the confirmation screen, click OK.
The device halts activity in the current mode and switches operation to the requested mode.
NOTICE: If you choose to turn off the power, set the rocker switch on the front of the
associated power supply to the Off (O) position.
f Disconnect the Ethernet cable from the transceiver module Ethernet service port.
g Repeat for each device in the configuration.
