TUNE UP PROCEDURE FOR PT4200-01
THE BUILT-IN CHANNELS ARE 15 CHANNELS +1 SCAN
CHANNEL
THE RANGE OF FREQUENCY IS 421--470MHz .
Before test/debugging, make sure all the equipments have been well connected to the
ground.
Before test/debugging, make sure the antenna output terminal has been connected
properly to the corresponding devices and load.
The transmitter output must pass RF power attenuator before being connected to the
standard signal source/ frequency deviator/ frequency spectrum.
When testing the receiver, make sure not to conduct transmitting operation.
When in debugging/testing/service, make sure static free measures for human body and
equipments.
