feature & functions.
A.3.3 Rotary Transmit Volume Control
The A10 Alpha allows you to adjust the volume of the outgoing sound
volume, and the high and low frequencies associated with it. To fine tune the
transmission volume, place a call and talk as usual using the headset. Slowly
rotate the
Rotary Transmit Volume Control (6)
with the small
screwdriver pin provided until the desired level is reached. The person
talking to you should be able to tell you when the optimum sound and tone
level is reached. Once this is set, there should be no need to make further
adjustments in the future.
Caution: Be careful when you adjust the volume control, as rotating
the volume to the maximum setting may cause headset to "squeal".
Reduce the volume and the "squealing" will disappear, but continuous
over-turning of the control may cause damage to the unit.

A.3.2 Power ON/OFF Switch (5)
Although the A10 Alpha will return to standby mode automatically after each
extended inactivity, you still want to turn it off when decided not to use for a
prolonged period of time to cut off the least consumption of power. Turning
off the unit does not affect normal telephone communication through the
handset, so you can answer or make phone calls through the handset as
usual.
A.3.1 External DC Supply Jack (1)
The unit provides the choice of using external DC supply
instead of batteries.
When purchasing an AC adapter, make sure the output polarity (+/- voltage)
matches the unit. And the voltage should be between 6V DC to 9V DC.
