Ambience Listening (AL) Call

Ambience Listening Call allows a dispatcher to make a special call that allows listening to the
conversations and background noises within the range of the microphone of a particular radio. The call
is set up without any indication to the affected radio, and any lower priority ongoing voice call or packet
data transfer may be preempted.
After accepting the call, the radio transmits in a simplex call without any action from or indication to the
user. The Ambience Listening Call automatically ends when you initiate any voice call, switch to
Emergency or TXI Mode, or send Emergency Alarm.

Bluetooth

Bluetooth is a wireless technology used to create personal networks operating in the 2.4 GHz
unlicensed band with a range of up to 10 m.
The radio supports Bluetooth 2.1 + EDR, Bluetooth 4.0, and Bluetooth Smart (BTLE). The Secure
Simple Pairing feature ensures a high level of security while pairing devices, thus protecting you
against recording and passive eavesdropping.
One radio can be connected with up to seven devices at the same time.
The usable range may be reduced when you connect the radio with devices that support more limited
ranges or if physical obstacles such as walls appear between devices. Five separate Bluetooth
features available:
• Bluetooth Audio and Object Push – includes Bluetooth Audio, Object Push Profile (OPP), and Fast
Push-to-Talk (PTT)
• Bluetooth Connectivity – includes Bluetooth Dial Up Networking (DUN) and Bluetooth Serial Port
Profile (SPP)
• Bluetooth Radio Control – includes Bluetooth Radio Control via AT commands and Bluetooth
Generic Attribute Profiles (GATT) Sensors
• Bluetooth Smart Proximity Pairing
• Bluetooth Smart Ready includes:
- Bluetooth Low Energy Indoor Location,
- Bluetooth Low Energy Heart Rate Profile

NOTICE: Bluetooth Audio and Object Push, Bluetooth Connectivity, Bluetooth Radio Control,
Bluetooth Smart Proximity Pairing, and Bluetooth Smart Ready are selling features.
You can use Bluetooth to:
• Connect the radio with wireless accessories, for example a headset, which gives you a greater
freedom of movement and increases your work comfort. Also, wireless accessories allow
performing the same activities in several ways. For example, you can change the volume level
either in the headset or on the radio.
• Send and receive files via OPP.
