Bluetooth® OPERATION

Operating Bluetooth

The IC-A25N and IC-A25NE have a built-in Bluetooth unit. You can connect Bluetooth headsets, or other Bluetooth devices to use some of navigation functions.

The communication range of Bluetooth is approximately 10 meters (33 ft).

Bluetooth

IC-A25N or IC-A25NE

Bluetooth headset (Example: Optional VS-3

NOTE:

• The Bluetooth communication range may vary, depending on the environment where you operate the device.

• The key beep sound may distorts when using the transceiver with a Bluetooth headset. Reduce the key beep level to prevent the distortion.

([MENU] > Sounds Settings > Beep)

•

You cannot switch the optional VS-3 Bluetooth headset to other devices, if the VOX level is set to 6.

([MENU] > Radio Settings > VOX Level)

Electromagnetic Interference

When you use a Bluetooth device, pay attention to the following: Bluetooth devices operate in the 2.4 GHz band. The

2.4 GHz band is also used by other devices, such as Wireless LAN products, microwave ovens, RFID systems, amateur radio stations, and so on. When using this device near such devices, interference may occur, causing a decrease in communication speed, and an unstable connection. In such cases, use this device away from the other devices, or stop using those devices.

Pairing with a device

D Weather Alert

(For only the IC-A25N and IC-A25C)

([MENU] > Radio Settings > Weather Alert) Turn the Weather Alert function ON or OFF. This function detects the weather alert tone on Weather channels. The National Oceanic and Atmospheric Administration (NOAA) broadcast station transmits a weather alert tone before any important weather information. (p. 9-3)
