T6T 300 Watt VHF Transmitter Page 98 Maintenance
Introduction
This topic gives the scheduled and unscheduled maintenance procedures for the T6T 300 watt VHF
transmitter and shows how to use the Virtual Front Panel (VFP).
Configuration
T6 radios are configured in respect of hardware and software.
Hardware Configuration
The transmitter consists of a drive assembly, three amplifiers and a combiner. Each has an identification
label showing the model, part number, serial number and the modification state. The modification state
identifies the hardware configuration.
Scheduled Maintenance A scheduled maintenance procedure is given on page 100.
Park Air recommends that this task be completed every twelve
months.
Unscheduled Maintenance Normally, the T6T transmitter is considered a Line Replaceable
Unit (LRU) and should be replaced with a serviceable spare if a
fault occurs. The faulty transmitter should then be returned to Park
Air for repair.
In certain circumstances, Park Air Customer Support may suggest
that the user change one of the transmitter modules. Dismantling
and assembly instructions are therefore given under the heading
Unscheduled Maintenance starting on page 104.
Using the VFP Operating parameters can be set from the drive assembly’s front
panel, or by using the VFP. Some additional functions are available
from the VFP. See page 126.
