Note:
It is recommended that you always use the headset, otherwise you will not
benefi t from the GN 8210’s features and protection.
4.2 Muting a call
To mute a call so that the other party is not able to hear you,
set the mute switch (F) to the mute position. The mute indi-
cator (F) will fl ash and low beeps will be heard in the head-
set every 10 seconds to indicate that mute is activated.
4.3 Automatic Volume Adjust
The volume of incoming calls is regulated by the Automatic Volume Adjust function,
which is built into the amplifi er. Automatic Volume Adjust automatically adjusts each
incoming call’s volume to the same level as that of the previous call, giving you a con-
sistent volume for each and every call you receive.
At any time, you may change the volume of incoming calls by adjusting the manual
headset volume control (G). The volume of your next incoming call will then be at this
new level.
4.4 Visual indicators
The amplifi er has two visual indicators: the on-line indicator (A)
on the headset stand and the mute indicator (F).
On-line indicator
The on-line indicator (A) fl ashes when speech is detected, indi-
cating to others that you are on a call.
When the amplifi er is fi rst connected to power through the power
adapter, the on-line indicator (A) fl ashes rapidly for 2 seconds.
Mute indicator
A fl ashing mute indicator (F) indicates that you have muted the
call, and that the other party is not able to hear you.
When the amplifi er is fi rst connected to power through the
power adapter, the mute indicator fl ashes rapidly for 2 sec-
onds.
