S-Meter Adjustment - Icom IC-80AD Service Manual

5-12 S-METER ADJUSTMENT

1) Select an adjustment item using [2] / [8].
2) Set the SSG as specifi ed (frequency, deviation and output level).
3) Push the [BAND] to adjust (automatic) and store the adjustment value.

"RECEIVE SENSITIVITY" must be adjusted before "S-METER CURVE" and "S-METER S3 LEVLE."
Otherwise, "S-METER CURVE" and "S-METER S3 LEVLE will not be adjusted properly.
