Potentially Explosive Environments
Switch your Jitterbug OFF when in any area with a potentially explosive atmosphere and
obey all signs and instructions. Sparks in such areas could cause an explosion or fire
resulting in bodily injury or even death.
Users are advised to switch the phone OFF while at a refueling point (service station).
Users are reminded of the need to observe restrictions on the use of radio equipment
in fuel depots (fuel 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 below deck on boats, chemical transfer or storage facilities, vehicles using
liquefied petroleum gas (such as propane or butane), areas where the air contains
chemicals or particles (such as grain, dust or metal powders) and any other area where
you would normally be advised to turn OFF your vehicle engine.

Emergency Calls
The Jitterbug, like any wireless phone, operates using radio signals, wireless and
landline networks as well as user–programmed functions, which cannot guarantee
connection in all conditions. Therefore, you should never rely solely on any wireless
phone for essential communications (medical emergencies, for example).
Remember, to make or receive any calls, the phone must be switched on and in a service
area with adequate signal strength. Emergency calls may not be possible on all wireless
phone networks or when certain network services and/or phone features are in use.
Check with local service providers.
To make an emergency call:
1. If your Jitterbug is not on, turn it on.
2. Key in the emergency number for your present location (for example, 911 or other
official emergency number). Emergency numbers vary by location.
3. Press the key.
