(5) Connect multimeter to test point A1A1TP1 (E31) using probe.
(6) Adjust potentiometer R26 for a 10.00-V dc indication on multimeter (R).
(7) Adjust RF TUNING control for frequency of 80 MHz.
(8) Adjust capacitor A1A1C21 for an 80 MHz indication on frequency counter. If
frequency counter indication cannot be obtained, adjust band D coil A1A2L6 for an 80 MHz
indication on frequency counter (R).
(9) Adjust RF TUNING control for frequency of 53.5 MHz. If frequency counter
does not indicate 53.5 MHz, adjust band D coil A1A2L6 for 515 MHz (R).
(10) Adjust RF TUNING control for frequency of 80 MHz. If frequency counter does
not indicate 80 MHz, adjust capacitor A1A1C21 for 80 MHz (R).
(11) Check tracking over entire band. If proper reading cannot be obtained, readjust
capacitor A1A1C21 and band D coil A1A2L6 (R).
(12) Set BAND SWITCH to C.
(13) Adjust potentiometer R27 for a 100.0 V dc indication on multimeter (R).
(14) Adjust RF TUNING control for frequency of 54 MHz. If frequency counter does
not indicate 54 MHz, adjust band C coil A1A2L 5 for 54 MHz (R).
(15) Check tracking over entire band. If proper reading cannot be obtained, readjust
band C coil A1A2L5 (R).
(16) Set BAND SWITCH to B.
(17) Adjust potentiometer R28 for a 10.70 V dc indication on multimeter (R).
(18) Adjust RF TUNING control for frequency of 38 MHz. If frequency counter does
not indicate 38 MHz, adjust band B coil A1A2L4 for 38 MHz (R).
(19) Check tracking over entire band. If proper reading cannot be obtained, readjust
band B coil A1A2L4 (R).
(20) Set BAND SWITCH to A.
(21) Adjust potentiometer R29 for an 8.30 V dc indication on multimeter (R).
(22) Adjust RF TUNING control for frequency of 205 MHz. If frequency counter
does not indicate 26.5 MHz, adjust band A coil A1A2L3 for 260 MHz (R).
(23) Check tracking over entire band. If proper reading cannot be obtained, readjust
band A coil A1A12L3 (R).
