www.algosolutions.com 4
Soft clicks are provided when pressing volume
keys until maximum or minimum level is
reached. The audio level settings will reset to
default after 60 seconds of silence to the
receiver.
Audio States
There are three audio states per user:
1. Normal
2. Mute
3. Exclude
Normal In Normal mode, both the microphone and
the speaker are operational and the audio is
heard and transmitted normally. A high tone
is provided when entering Normal mode.
Mute In Mute mode, the microphone is disabled,
preventing transmission of audio from the
user’s handset or headset. A medium tone is
provided when entering Mute mode. When
the Mute mode is active, the light on the Mute
key will be on.
Exclude In Exclude mode, both the microphone and
the speaker will be disabled. A low tone is
provided when entering Exclude mode. In
addition, when the Exclude mode is active,
the light on the Exclude key will be on.
Note that Mute and Exclude modes are
mutually exclusive so pressing the Mute key
while in Exclude mode will switch to the
Mute mode and deactivate the Exclude
mode.
