Switch off your device before boarding an aircraft. The use of wireless teledevices

in an aircraft may be dangerous to the operation of the aircraft and may be illegal.

Potentially explosive environments

Switch off your device in any area with a potentially explosive atmosphere. Obey

all posted instructions. Sparks in such areas could cause an explosion or fire

resulting in bodily injury or death. Switch off the device at refuelling points such as

near gas pumps at service stations. Observe restrictions in fuel depots, storage, and

distribution areas; chemical plants; or where blasting operations are in progress.

Areas with a potentially explosive atmosphere are often, but not always, clearly

marked. They include areas where you would be advised to turn off your vehicle

engine, below deck on boats, chemical transfer or storage facilities and where the

air contains chemicals or particles such as grain, dust, or metal powders. You should

check with the manufacturers of vehicles using liquefied petroleum gas (such as

propane or butane) to determine if this device can be safely used in their vicinity.

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 will 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 profile mode to an active profile.
