22.3.1
TRANSMITTER FUNCTIONAL TEST
CAUTION
Contact RFL Service before performing the following procedures. Extreme care should be
taken when potentiometer settings are changed.
The following Functional Test Procedure, which is organized by Transmitter section
followed by the Receiver section, should not be required if the customer’s purchase order
specified configuration settings prior to factory shipment.
This procedure is intended for reconfiguring, troubleshooting, or performance verification.
1)
The transmitter frequency was factory-set according to strapping charts on the equipment
drawings. If necessary, the center frequency can be set via
SW3 through SW 7** (middle row).
The 9785 On-Off carrier set does not utilize frequency shifts. Therefore, the frequency shift
switches are set to zero
(SW1-SW*2 and SW8-SW9*).
