2: Installation
2-18 PRC1077-MSOP
To install the PRC1077 into a 24 Vdc 50W mobile system (refer to the figure
on page 2-17):
1. Without installing a battery, install the battery box onto the PRC1077
transceiver case (refer to "Installing the Battery" on page 2-2).
2. Slide the PRC1077 transceiver onto the MT-1077-24 adapter and clamp it
in place with the two mounting clamps. The MT-1077-24 includes an
integrated shock mount.
3. Install the AM-1077ADPT RF amplifier adapter to the back of the
AM-1077 RF amplifier case.
4. Position the AM-1077 50W RF amplifier on top of the PRC1077
transceiver case and install the two handle clamps to the front-panel
handles to secure the AM-1077 amplifier to the PRC1077.
5. Connect the C991579 cable to the AM-1077 RF amplifier DC POWER
INPUT connector and to the MT-1077-24 adapter AMP CNTL connector
(J3).
6. On the PRC1077, remove the protective cap from the POWER connector.
Connect the C991949 cable to the PRC1077 POWER connector and to
the MT-1077 SET PWR connector (J4).
Note: Make sure the POWER connector protective cap is attached to the
PRC1077 transceiver front panel by a cord so it will not become lost. The
protective cap grounds the connector when the cap is installed. If the
protective cap is not installed or the C991949 cable is not installed and
connected to the MT-1077 adapter, the PRC1077 will not operate.
7. Connect the C991577 cable to the AM-1077 RF amplifier 50 ohm RF
OUT connector and to the 4242-MK2 antenna.
