ADJUSTMENT

1) Adjustment Spot

Power Supply Voltage 13.8V

Output of SSG is all EMF indication.

If without instruction, SSG output is MOD 1KHz DEV 3.5KHz/DEV.

(DR-M03R)

If without instruction, SSG output is MOD 1 KHz DEV 1.75KHz/DEV. (DR-03T)

Standard modulation is also based above.
Speaker load is 8 ohm and output is 5 0 - 1 0 0 mV.
