DECIMAL 7 (far left digit) = "1"
DECIMAL 6 = "2"
DECIMAL 5 = "0"
DECIMAL 4 = "0"
DECIMAL 3 = "1"
DECIMAL 2 = "0"

POWER ADJUST pot.
31. Tweak the front panel POWER ADJUST pot fully clockwise to verify that the output power goes to the set
maximum power. Tweak the POWER ADJUST pot counter-clockwise verifying that the output power drops as
tweaking. The output power should be close to 0 Watts when the POWER ADJUST pot is fully counter-clockwise.
32. Adjust the POWER ADJUST pot to the desired output power.
33. If you are not satisfied with the maximum output power, first adjust the front panel POWER ADJUST pot fully
clockwise for maximum power, then adjust the MAX PWR pot (R74) on the SYNTHESIZER to the desired
maximum output power, but again, do not exceed the Maximum RF Output Power as specified in ORDERING
INFORMATION corresponding to your model.
34. Replace the cover on the SYNTHESIZER.
35. On the FRONT PANEL CONTROL & METER board, adjust S1 dip-switches with switch 1 and 2 "ON", and 3 and
4 "OFF". This places the SRPT-40A back into normal operation.
