Connect RF SSG to ANT Connector (J501) and set it 27.185MHz. Connect AF VTVM to EXT. SPK. Jack (J3). Adjust coils for maximum reading on AF VTVM.

2

Same as above.

VR4

Set the SSG Attenuator to 0.25uV and adjust the output power to normal position. If the output power is less than normal, keep resistance value of VR4 at minimum (CW) and keep it at maximum (CCW) if over normal to the contrary.

Same as Step 1 except
SQL: MAX

VR1
(Squelch)

Set the RF Signal Generator to 1000uV output level. Adjust VR1 for 2V on AF VTVM.

4

Same as step 1
No Modulation

VR3

Set the RF Signal Generator to 1000uV output level. Adjust VR3 so that 4th digit of LED meter of the unit just illuminates.
