B.1.7 Transmission Volume
The Series A20 Omega allows you to adjust the volume of the outgoing
sound on the main interface. To fine tune this transmission volume, make
sure that the slide control is adjusted to the middle on initial adjustment,
then place a call and talk as usual using the headset. Slowly slide the
Microphone Volume Control Slide Switch (10) until the desired level is
reached. The person talking to you at the other end should be able to tell
you when the optimum sound and tone level is reached.
B.1.6 Reception Volume
The Reception Volume Control Slide Switch (12) is for adjusting the
volume of the sound to the headset. By sliding the button left and right, you
can obtain a desired volume. Varying from different telephone systems, the
volume gain may be different, however, setting the level to the middle should
be safe for initial use.
