TUNE UP PROCEDURE FOR PT4200-01

 

 

z

 

THE BUILT-IN CHANNELS ARE 15 CH1 SCAN 

CHANNEL  

z

 

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.
