11
Introduction
The battery indicator shows one of four states: full, half, low, and critical. Replace the batteries
when the 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.
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 confirm the device
is in the desired activation mode (see “Accessing nVISION Settings” on page 34).
Remove the batteries and disconnect the sensor if the device is to be stored for more than
1 month. Do not store with batteries installed.
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 6.5 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 (January 1st, 2010 at
12:00 a.m.).
Bluetooth Technology (3150 BLE only)
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 SpO2 and pulse rate data to be transmitted
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.
Nonin’s WristOx2, Model 3150 BLE, uses a Bluetooth Low Energy radio with a maximum range
(spherical radius) of about 60 meters (196 feet). Obstacles and other conditions may affect
range and battery life. See “Specifications” for detailed battery life information.

12
Modes
Modes
The WristOx2, Model 3150, has two types of mode settings: Activation and Display, which are
described below.
Activation Modes
Activation modes determine how the 3150 turns off and on. Spot Check Activation Mode is the
factory default.
Spot Check Activation Mode
In this activation mode, the 3150 will automatically turn on when a finger is inserted into the
sensor. It will turn off 10 seconds after the finger is removed. If the sensor is disconnected, the
device turns off immediately.
NOTE: If the device determines that a sensor fault exists (a sensor failure, misalignment,
or incompatibility with the device) or if a pulse oximeter sensor signal cannot be detected,
the device turns off after 3 minutes.
Sensor Activation Mode
In this mode, the device turns on when the activation switch is pressed or when the sensor is
disconnected and reconnected. This mode is useful when using a sensor that is not easily
removed from the patient (e.g., disposable or wrap sensor).
If the sensor is not used or an inadequate pulse signal is detected for at least 10 minutes, the
device will turn off. To turn the device on again, press the activation switch or disconnect and
reconnect the sensor.
Programmed Activation Mode
When in Programmed Activation Mode, the user can program the device to turn on for up to
three sessions. In between the programmed sessions, the device will turn off. When off, the
device will display the next session start time every 30 seconds.
A sensor must be connected to the 3150 in order for the 3150 to turn on at the programmed
session time.
Between the programmed sessions, pressing the activation switch will turn on the device for
three minutes. During this time, the user is able to take and store measurements. After three
minutes, the device will turn off.
!
CAUTION: When setting the clock in Programmed Activation Mode using nVISION
software, verify all session dates and times are valid.
!
CAUTION: A device in Programmed Activation Mode reverts to Spot Check
Activation Mode if the clock is not set or if the clock settings are lost when replacing
the batteries or due to critical battery level.

13
Modes
Display Modes
Full Display Mode is the factory default.
Full Display Mode
Full Display Mode will display SpO2, pulse rate, the animated pulse strength indicator and
battery life on the display (as well as the connection status for the 3150 BLE.)
Partial Display Mode
When using Partial Display Mode, the SpO2 and the pulse rate readings do not display. The
user will only see the battery indicator and the animated pulse strength indicator. See figure 2
below for display comparison with Full Display Mode.
Figure 2: Comparison of Full and Partial Display
Partial Display Mode is not supported in Spot Check Activation Mode.
Memory Volume (MVI) Display Mode
Memory Volume (MVI) Display Mode is selected using nVISION software (version 6.5 or
greater). Memory Volume Display Mode is used to quickly see how many hours and minutes of
valid data are stored in the device’s memory.
In Memory Volume Display Mode, the display screen (figure 3) only shows:
• The volume of data (in hours and minutes) stored in memory
• hours: display range of 0 – 199
• minutes: display range of 0 – 59
• The battery indicator
• The pulse strength indicator
When the animated pulse strength indicator displays, the device is recording data. The number
next to the indicator are the minutes of stored data, not the pulse rate.
NOTE: When the device is in Memory Volume Display Mode, the %SpO2 and pulse rate
readings do not display on the screen.
