Unit Description (18-0015) AM-48 Test Set

Note: Switch 3 and Switch 14 control the speaker/
earphone monitoring point. See Figure 9-1 for a
block diagram showing the interaction of these
switches. When Switch 3 is set to <DAMP>, the
monitor point is after the auto-range amplifier,
which significantly increases the speaker level.

sounds much higher than the speaker level. Be careful
to adjust the audio volume down before inserting the
earphone into the ear.
