ADJUSTMENTS
This set has been aligned at the factory and normally will not require further adjustment. As a result, it is
not recommended that any attempt is made to modificate any circuit. If any parts are replaced or if any-
one tampers with the adjustment, realignment may be necessary.
IMPORTANT
1. Check Power-source voltage.
2. Set the function switch to band being aligned.
3. Turn volume control to minimum unless otherwise noted.
4. Connect low side of signal source and output indicator to chassis ground unless otherwise specified.
5. Keep the signal input as low as possible to avoid AGC and AC action.
