SAFETY WARNINGS
Chapter 2 – Safety Warnings
Radio Frequency (RF) Safety
Due to the possibility of radio frequency (RF) interference, it is important that you follow any special regulations
regarding the use of radio equipment. Follow the safety advice given below.
Operating your device close to other electronic equipment may cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.
Different industries and businesses restrict the use of cellular devices. Respect restrictions on the use of
radio equipment in fuel depots, chemical plants, or where blasting operations are in process. Follow
restrictions for any environment where you operate the device.
Do not place the antenna outdoors.
Switch OFF your wireless device when in an aircraft. Using portable electronic devices in an aircraft may
endanger aircraft operation, disrupt the cellular network, and is illegal. Failing to observe this restriction
may lead to suspension or denial of cellular services to the offender, legal action, or both.
Switch OFF your wireless device when around gasoline or diesel-fuel pumps and before filling your vehicle
with fuel.
Switch OFF your wireless device in hospitals and any other place where medical equipment may be in use.
Interference with Pacemakers and Other Medical Devices
Potential interference
Radio frequency energy (RF) from cellular devices can interact with some electronic devices. This is
electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted
cardiac pacemakers and defibrillators from cellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that
cardiac pacemakers and defibrillators are safe from cellular device EMI.
The FDA continues to monitor cellular devices for interactions with other medical devices. If harmful interference
occurs, the FDA will assess the interference and work to resolve the problem.
Precautions for pacemaker wearers
If EMI occurs, it could affect a pacemaker in one of three ways:
Stop the pacemaker from delivering the stimulating pulses that regulate the heart's rhythm.
Cause the pacemaker to deliver the pulses irregularly.
Cause the pacemaker to ignore the heart's own rhythm and deliver pulses at a fixed rate.
Based on current research, cellular devices do not pose a significant health problem for most pacemaker wearers.
However, people with pacemakers may want to take simple precautions to be sure that their device doesn't cause
a problem.
Keep the device on the opposite side of the body from the pacemaker to add extra distance between the
pacemaker and the device.
Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or
jacket pocket directly over the pacemaker).

INSTALLING AND USING THE DEVICE
Chapter 3 – Installing and Using the Device
Installing the Device
1. Connect suitable antenna(s) to the antenna connector(s).
2. If your device is the serial version:
Connect the DE9 male connector (9-pin) of the RS-232 cable to the RS-232 connector on the device, then
connect the other end to the serial port on the other desired device.
Screw-on the power lead from the power supply module into the power connection on the device.
Plug the power supply into your power source.
3. If your device is the USB version:
For information about the USB cable that helps power your device, see the section "USB Cable
Recommendations."
The USB cable uses power from the USB power line. Connect one end of the USB cable to your computer
or other USB high power device, such as a hub.
Connect the other end to the device's USB connector.
4. The POWER LED lights after the device powers up.
Placing Serial Devices in Power Save Mode
The serial devices offer a low power mode (sleep or power save mode) using the power save switch (below the
SIM card slot) on the device to change from normal or low power mode. The low power mode is intended for
battery or solar-powered, IoT applications such as outdoor remote sensors.
There are other techniques to place the device into low power mode. This example uses data terminal ready (DTR)
and the AT command +CFUN=5. For other techniques, review the AT command guide for your device, as described
in the Documentation section of this guide.
The device also wakes up from sleep mode by using the wake-on-ring feature. See the following example using the
ring indicator line to wake the host processor when the radio receives an incoming call or SMS message. Your
application then needs to act on the ring indication and wake up the device by asserting DTR.
Using Low Power Mode
Here are some different configuration options for low power mode:
To turn on low power mode, set the power-save switch to LOW.
On the RS-232 interface, ensure your application controls DTR and makes it active (on). To configure the
device for DTR control, issue either AT&D1 or AT&D2 for DTR control. The &D0 command does not allow
low power to operate.
To configure the device to enter low power (sleep) mode, issue AT+CFUN=5 to the radio.
To configure the device to wake from low power mode by using the wake-on-ring feature, issue
AT#E2SMSRI=1000. This configures the ring indicator to go active for 1000 ms when an SMS message is
received.
To have the device enter sleep mode, set DTR to inactive (off) on the RS-232 interface. The clear to send
(CTS) signal is off when the device is in sleep mode.
MultiConnect®Cell MTC-MNA1 User Guide 15
Page 16
INSTALLING AND USING THE DEVICE
USB Cable Recommendations
