After soldering, remove residual flux with a suitable solvent. Rubbing alcohol is highly diluted and is not
effective.
The board should be checked to ensure the flux has been removed. Rosin flux is not normally corrosive;
however, the flux will absorb enough moisture in time to become conductive and cause problems.
INTEGRATED CIRCUITS. Special care should be exercised with integrated circuits. Each integrated circuit must
be installed by matching the integrated circuit notch with the notch on the socket. Do not attempt to remove
an integrated circuit from a socket with your fingers. Use an integrated circuit puller to lightly pry the
component from the socket.
5.4.1
EXCITER PREPARATION FOR SHIPMENT.
If the exciter is removed from service to be shipped to another location, ensure the following steps are
accomplished prior to shipping:
A. Secure the modulated oscillator assembly in place with two 6-32 X 3/4 inch (1.27 cm) screws in the
tapped holes provided.
B. Ensure the top-cover is secured to the exciter.
C. Pack the exciter in a carton, allowing 2 inches (5.08 cm) minimum of packing material all around the
exciter.
D. Provide adequate insurance coverage.
5.4.2
EXCITER FREQUENCY CHANGE.
If modification of the exciter frequency is required, perform the following procedures in sequence as listed.
A. FREQUENCY SELECTION procedure in the AFC/PLL section of this manual.
B. MODULATION CALIBRATION procedure in the AFC/PLL section of this manual.
C. MODULATION CORRECTION procedure in the AFC/PLL section of this manual.
D. FWD CAL (R5) AND RFL CAL (R9) procedure in the POWER SUPPLY/CONTROL section of this manual.
