18 Bluetooth® If you purchase a commercially available headset that is compatible with Bluetooth, you can connect the transceiver and headset to perform communication wirelessly. For example, you can wirelessly connect them with the transceiver as the main device and the commercially available headset or other device as the sub device. The transceiver supports the following profiles. HSP (Headset Profile): Profile for communicating with headsets. SPP (Serial Port Profile): Profile used for setting up virtual serial ports on two devices (e.g. PCs) and then connecting those devices. NOTE ◆◆ Profiles are Bluetooth connection protocols. ◆◆ Purchase a commercially available headset or other device that is compatible with Bluetooth. ◆◆ With Bluetooth communication, the communication distance varies significantly depending on the influence of nearby equipment. Interference from equipment such as a microwave oven or a wireless LAN will influence the communication distance. In such a case, try stopping the other wireless communication, stopping use of the microwave oven or other equipment, and moving the transceiver away from any nearby equipment. The communication problem may also be resolved by moving the Bluetooth device and transceiver as close to each other as possible. TURNING ON/ OFF THE Bluetooth FUNCTION You can turn On/ Off the Bluetooth function. 1 Access Menu No. 930.

When the headset is connected, < > appears on the display. • Since the connection operation depends on the headset, refer to the instruction manual of the headset. Connecting with a Headset (Pairing) When connecting the transceiver with a Bluetooth compatible device, you need to first pair the devices. Pairing is a function for registering devices for a Bluetooth connection as a connection pair. The following explains how to connect via Bluetooth using the example of a commercially available headset. NOTE ◆◆ For the device to be connected with the transceiver via Bluetooth, be sure to purchase a headset or other device that is compatible with Bluetooth. Also refer to the instruction manual of the device. ◆◆ A connection may not be possible depending on the specifications or settings of the device. There is no guarantee that the transceiver will be able to communicate wirelessly with all Bluetooth devices. ◆◆ The audio bandwidth supported in HSP (Headset Profile) is 4 kHz and below. The voice quality of the received audio with a signal component of 4 kHz and above such as FM radio, may sound different from speakers or earphones. Note: ◆◆ The volume of the headset can not be adjusted by the [VOL] control of the transceiver. Adjust the volume by the headset volume. 18-1
