■ Emergency calls
Important: This device operates using radio signals, wireless networks, landline
networks, and user-programmed functions. If your device supports voice calls over
the internet (internet calls), activate both the internet calls and the cellular phone.
The device may attempt to make emergency calls over both the cellular networks
and through your internet call provider if both are activated. Connections in all
conditions cannot be guaranteed. You should never rely solely on any wireless
device for essential communications like medical emergencies.
To make an emergency call:
1. If the device is not on, switch it on. Check for adequate signal strength. Depending on
your device, you may also need to complete the following:
• Insert a SIM card if your device uses one.
• Remove certain call restrictions you have activated in your device.
• Change your profile from Offline or Flight profile to an active profile.
2. Press the end key as many times as needed to clear the display and ready the device for
calls.
3. Enter the official emergency number for your present location. Emergency numbers vary
by location.
4. Press the call key.
■ Hearing aid compatibility (HAC)
Warning: For hearing aid compatibility, you must turn off the Bluetooth
connectivity.
Your mobile device model complies with FCC rules governing hearing aid compatibility.
These rules require an M3 microphone or higher value. The M-value, shown on the device
box, refers to lower radio frequency (RF) emissions. A higher M-value generally indicates
that a device model has a lower RF emissions level, which may improve the likelihood that
the device will operate with certain hearing aids. Some hearing aids are more immune than
others are to interference. Please consult your hearing health professional to determine the
M-rating of your hearing aid and whether your hearing aid will work with this device. More
