Cautions
In general
Bluetooth is an industrial specification for low-powered, short-range wireless networking. It provides a
way to connect, and exchange information between, devices. Bluetooth is used not only in cellular phones
and handsets but also personal computers, as well as other devices such as video game consoles.
Bluetooth devices use a globally recognized, secure, unlicensed, short-range radio frequency.
Bluetooth compatibility
Not all Bluetooth-enabled headsets are alike, because different manufacturers implement Bluetooth
slightly differently. To minimize such issues, a headset should comply with the Bluetooth 1.2 (or higher)
specification.
Still, even then, there can be difficulty in making Bluetooth devices interact. In particular, a Bluetooth-
enabled headset may:
• Fail to pair with the ESI Bluetooth Headset Interface.
• Turn off its Bluetooth capability by itself, due to either a power-saving setting or interference from
other devices.
• Suffer noisy or bad connections on calls. This can occur for a variety of reasons. The headset may
be too far away from the ESI Bluetooth Headset Interface, or it may encounter interference from
other Bluetooth devices (or even other objects such as walls, appliances, and cordless phones).
Some headsets turn off while charging, causing the HEADSET LED to glow solidly. To reconnect the
headset after charging, just turn the headset back on.
Here is a short list of headsets that ESI used while beta-testing the ESI Bluetooth Headset Interface
(but this is not intended as an endorsement of any of these, nor as a statement that they will always
work properly with it). For additional updates, visit www.esi-estech.com/BT.
