Kyocera FS-820 Cordless Telephone User Manual


 
[4]
The phone comes with a rechargeable battery pack. Three types of batteries are available for use
with this phone. Remember to fully charge the battery as soon as its charge gets low to
maximize available talk and standby times.
Installing and removing the battery
The battery pack snaps easily into the back of the phone, bottom end first, for quick installation
and removal. To ensure you do not lose stored numbers and messages, always turn off the phone
before removing the battery.
Charging the battery
The battery charge level icon appears in the upper-right corner of the phones screen.
When the battery charge level is low, the message Low Battery appears and the phone sounds
a tone. If the battery level becomes too low, the phone turns itself off and any function in
progress is not saved.
NOTE: Charge your battery when you see the icon begin to blink. Use the standard Kyocera
Wireless Corp. AC adapter charger or the optional travel charger, desktop charger, or cigarette
lighter adapter to recharge the battery.
NOTE: You do not need to completely discharge the battery before charging. Unlike other battery
systems, lithium ion has no memory effect that could degrade battery performance.
WARNING: Use only Kyocera Wireless Corp.-approved chargers and adapters. Using another adapter may be dangerous and
will invalidate the phone warranty if said accessories cause damage or a defect to the phone.
1. If the battery is not installed, snap it into place on the back of the phonebottom
end first.
2. Plug the standard AC adapter into a wall outlet.
3. Insert the other end of the cord into the bottom of the phone. A message indicating
the battery is charging should appear immediately. Charging a completely discharged
standard Extended Li-ion battery takes approximately 6 hours; the Slim Li-ion battery
takes approximately 4 hours; and the Ultra-Light Li-ion battery takes approximately
2.5 hours (see Accessories later in this guide).
NOTE: If the phone is turned on, CH appears in the upper-left corner of the screen and
indicates the battery is charging. If the phone is turned off, the message Battery is Charging
appears.
