TM-P60 Technical Reference Guide A.3 Using Bluetooth Effectively ❏ See “Communication Range” on page A-8 for information about Bluetooth communication range. ❏ Place Bluetooth compatible devices away from other electrical devices. Do not operate near automatic doors, fire alarms, etc., as a malfunction could occur. Using a device such as a microwave oven that emits strong high-frequency energy may cause interference. If this occurs, relocate the Bluetooth device(s) to a location with less interference. ❏ If a device that uses the same frequency range is located nearby, improper communication may result. If this occurs, relocate the printer device(s) to a location with less interference.
❏ Bluetooth and wireless LAN use the same frequency range (2.4GHz). Using both types of devices near each other can cause interference. Make sure to separate by 10 meters or more. WARNING : ❏ Do not use near medical devices. Bluetooth radio waves may interfere with heart pacemakers or other electrical medical devices. ❏ Make sure to use at least 22cm or more away from any heart pacemakers. Bluetooth radio waves could effect pacemaker operation. ❏ Do not use Bluetooth devices near automatically controlled devices such as automatic doors or fire alarms. Bluetooth radio waves can cause these devices to malfunction and may result in injury. Rev. A About Bluetooth A-9
