Unscheduled Maintenance
The instructions given in this section involve connecting dangerous voltages to the
transceiver. The instructions detailed in this document must be carried out only by suitably
qualified personnel.
When an ac supply is connected, lethal voltages are present within the transceiver. Care
must be taken by personnel to avoid accidental contact with exposed circuitry during
maintenance or alignment procedures.
When the power switch is set to the off position, lethal voltages are still present in the
transceiver's internal power supply circuitry. To ensure safe working, the ac and dc input
supplies must be disconnected from the transceiver.
The antenna used with the transceiver must be installed such that the resultant radiated field
strength is below 10 W/m² in areas normally accessible to personnel.
The T6TR transceiver’s circuitry contains Electrostatic Sensitive Devices (ESSDs).
Personnel must be aware of the precautions necessary to prevent damage to such devices.
Changes or modifications made to this equipment that are not expressly approved by
Park Air, or parties authorized by Park Air, could void the user’s authority to operate the
equipment.
When carrying out repairs to the PA module, care must be taken not to damage the gasket.
If the strips become damaged, they must be replaced. Failure to comply with this instruction
may compromise the transceiver’s Electromagnetic Compatibility (EMC) and breach
European Commission regulations.
When screws are inserted into the transceiver PA casting care must be taken not to exceed
a torque of 6 Ibs/inch when tightening. This applies when replacing the top and bottom
covers and during the refitting of the PA module.
