Precautions
On BLUETOOTH communications
BLUETOOTH wireless technology operates within a range of about 10 m (30 feet)
may vary depending on obstacles (human body, metal, wall, etc.) or electromagnetic environment.

Approx. 1 km (0.62 mile) for Group Talk.
The antennas are built into the main unit and remote control as illustrated in the dotted line. The sensitivity of the
BLUETOOTH communications will improve by turning the direction of the built-in antenna of the main unit to the
connected BLUETOOTH device. If there is obstacle between the antenna of the connected device and built-in
antennas of the main unit and remote control, noise or audio dropout may occur, or communications may be
disabled.
1. Built-in antenna
BLUETOOTH communications may be disabled, or noise or audio dropout may occur under the following conditions.
There is a human body between the main unit and BLUETOOTH device.
This situation may be improved by placing BLUETOOTH device facing the antenna of the main unit.
There is obstacle such as metal or wall, between the main unit and BLUETOOTH device.
A device using 2.4 GHz frequency, such as a Wi-Fi device, cordless telephone or microwave oven, is in use near
the main unit.
Because BLUETOOTH devices and Wi-Fi (IEEE802.11b/g/n) use the same frequency (2.4 GHz), microwave
interference may occur resulting in noise or audio dropout, or communications being disabled if the main unit is used
near a Wi-Fi device. In such a case, perform the following.
Use the main unit at least 10 m (30 feet) away from the Wi-Fi device.
If the main unit is used within 10 m (30 feet) of a Wi-Fi device, turn off the Wi-Fi device.
Install the main unit and BLUETOOTH device as near to each other as possible.
Microwaves emitting from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off the
main unit and other BLUETOOTH devices in the following locations, as it may cause an accident:
where inflammable gas is present, in a hospital, or a petrol station
near automatic doors or fire alarms.
Due to the characteristic of the wireless technology, the sound played on the main unit is delayed from the sound and
music played on the sending device.
NYSNO-10 supports security capabilities that comply with the BLUETOOTH standard to provide a secure connection
when the BLUETOOTH wireless technology is used, but security may not be enough depending on the setting. Be
