Dual Microphones

Each radio has two microphones. One at the top of the unit for dispatch (simplex) operation, and
another at the bottom of the unit for duplex calls.
While the ambience listening is active or while being in the Covert Solution, you cannot switch to the
high audio mode by pressing the speaker control key.

Audio Toggle

You can control audio routing between the speaker and earpiece for any private or group call through
the dedicated Speaker Control key. You can also define through the menu to have all group calls in
high audio or controlled by the Speaker Control key.

Volume Adjustment Mode

You can set the volume to Individual or Common. When set to Common, the audio has one setting for
all items.
When set to Individual, the volume level for the following options can be set per user preferences.
• Voice
• Duplex
• Simple
• Keypad
• Tones
• Call-Out
The Volume Control Mode is configurable using the Customer Programming Software (CPS).
NOTICE: When a volume control capable Bluetooth device is connected, the radio always uses
the Common setting.
You can configure the maximum volume offsets (dB) and the volume range (dB) through CPS. The
field is Audio Settings→User Profile. The volume control in the radio is divided into 13 steps, from 0
to 14. If for example, the vol. range is set to 39, each step on the volume indication bar is 3 dB.

Accessory (Accry) Setup

You can connect IMPRES, CORE, Other, or Secondary accessories to the radio side connector. You
can connect accessories to the audio connector at the bottom of the radio.
If you connect an IMPRES accessory, the radio detects and recognizes the accessory automatically. If
you connect a CORE, Other (for example, a third-party accessory), or Secondary accessory (for
example, an earpiece connected to an RSM), the radio may detect the connection but manual
selection is required at the Accry Setup menu.
If you connect an accessory, the radio detects the connection and selects the IMPRES accessory
automatically.
