Understanding How Your Jitterbug Operates
Your Jitterbug is basically a radio transmitter and receiver. When it’s turned on, it
receives and transmits radio frequency (RF) signals. When you use your Jitterbug, the
system handling your call controls the power level. This power can range from 0.006
watts to 0.2 watts in digital mode.
Maintaining Your Jitterbug’s Peak Performance
For the best care of your Jitterbug, only authorized personnel should service your
Jitterbug and accessories. Faulty service may void the warranty.
There are several simple guidelines to operating your Jitterbug properly and maintaining
safe, satisfactory service.
• To ensure that the Hearing Aid Compatibility rating for your Jitterbug is maintained,
secondary transmitters such as Bluetooth and WLAN components must be disabled
during a call.
• If your Jitterbug is equipped with an external antenna, hold the phone with the
antenna raised, fully–extended and over your shoulder.
• Do not hold, bend or twist the phone’s antenna, if applicable.
• Do not use the phone if the antenna is damaged.
• If your Jitterbug is equipped with an internal antenna, obstructing the internal
antenna could inhibit call performance.
• Speak directly into the phone’s receiver.
• Avoid exposing your Jitterbug and accessories to rain or liquid spills. If your
Jitterbug does get wet, immediately turn the power off and remove the battery. If it is
inoperable, call us for service.
