Bluetooth Technology - Nonin WristOx2 3150 Operator's Manual

Introduction
The battery indicator shows one of four states: full, half, low, and critical. Replace the batteries
when device reaches low state. A low battery has a minimum of 10 minutes before it reaches
critical state. Actual battery life depends on Bluetooth radio use. In critical battery mode:
• The battery indicator blinks.
• The device no longer monitors or records patient data.
• The clock settings are lost.
• The device reverts to Spot Check mode.
When batteries are removed in low battery mode, the device maintains the time and date for up
to 30 seconds. After battery replacement, check the device's screen during startup to ensure
date and time are set. Use nVISION software to synchronize the clock and change the operation
mode (see "Accessing nVISION Settings" on page 29).
Remove the batteries and disconnect the sensor if the device is to be stored for more than
1 month. In storage, battery life is approximately 9 months.
NOTES:
• This device contains non-volatile memory. Removing or replacing batteries does not affect
the data stored in memory. Stored data remains in memory until overwritten by newer data
or cleared from memory with nVISION software (version 6.3 or greater).
• If batteries are replaced while recording data, the session will terminate and some data
from the session may not be saved. The terminated session will be time stamped with the
current date/time the next time the device turns on.
• To avoid potential battery cell damage for all battery types, remove batteries from the
device when the critical battery indicator displays. Leaving rechargeable batteries in the
device during critical battery will decrease battery life.
• If clock settings are lost, the date and time restarts at 01:01:10:00:00.

Bluetooth Technology

Bluetooth technology allows wireless connections between electronic communications and
computing devices. The technology is based on a radio link that offers fast and reliable data
transmissions. Bluetooth uses a license-free, globally available frequency range in the ISM
band—intended to ensure communication compatibility worldwide.
Nonin's use of Bluetooth wireless technology allows SpO
through a Bluetooth radio to a compatible Bluetooth-enabled device. Nonin's wireless system
removes the cable connection from the device, giving patients increased ability to move freely.
To make efficient use of battery life, Nonin's WristOx
switchable Class 1/Class 2 Bluetooth radio with a maximum range (spherical radius) of about
100 meters (328 feet). Obstacles and other conditions may affect range, and class of operation
and connection mode will impact battery life. See "Specifications" for detailed battery life
information.
