CT-501 Handheld Flip-Style Cellular Phone
(170-1110) Battery Faxback Doc. # 45467
Using The Battery
WARNING: Like most batteries, your cellular phone's battery can be detach-
ed. A detached Battery could cause property damage, injury, or
burns if a metal object (such as a pen spring, beaded chain, or
piece of jewelry) contacts the battery's terminals and causes a
short circuit. Be careful when placing a charged battery inside
a coat pocket, purse, or other container that might contain con-
tain metal objects.
CAUTION: Nickel cadmium (Ni-Cd) batteries must be recycled or disposed of
properly. (You can put them in the battery recycling box at your
local RadioShack store.) They must not be disposed of in munici-
pal waste.
Installing The Battery
1. Place the battery flat against the back of the phone and align the top
of the battery with the line on the back of the phone (below the
raised arrows).
2. Slide the battery toward the top of the phone until it snaps into
place.
To remove the battery, be sure the phone is turned off, then press the
latch at the top of the battery and slide the battery toward the bottom
of the phone until it stops. Then lift the battery off the phone.
Note: If you have an extra charged battery and the currently installed
battery becomes low during a call, you can change the battery with-
out ending the call or losing the connection. See "Installing a
Fresh Battery During a Call" in Faxback Document # 45467.
Charging The Battery
The nickel-cadmium battery supplied with your telephone is shipped in a
discharged state to extend the battery's life. It must be fully charged
before you can use your phone.
We recommend that you charge a new battery overnight, but no longer than 24
hours, using the AC charger supplied with your phone. Subsequent charging
("recharging") time varies based on the type of battery and the amount of
charge left in the battery. See "Recommended Recharging Times" in Faxback
Document #45467.
Follow these steps to charge the supplied (or any approved) battery using
the charger supplied with your phone.
1. Install the battery on the phone.
2. Insert the charger's flat plug into the charging jack on the bottom of
the phone.
Note: The plug fits into the jack only one way. If you have difficulty
inserting the plug, turn it over and try again. Do not force it!
3. Connect the charger's AC plug to a standard AC outlet.
Notes: For fastest charging (if you are not expecting a call), be sure the
phone is turned off during charging.
You can use the phone while it is charging, but charging takes
longer.
4. When the battery is fully charged, disconnect the charger from the AC
outlet. Then press in the clips on the sides of the plug and pull the
plug away from the phone to disconnect the charger from the phone.

Checking Battery Power
The phone always displays a graduated set of up to three battery level
indicators (Symbol) when it is turned on. The more indicators that appear,
the higher the battery's current charge level.
To see a more detailed indication of the battery's charge level at any
time, press FCN 4. The battery strength meter appears on the display for
about 5 seconds. Read this meter in the same way.
When battery power becomes low, the phone displays Lo bAt and sounds a
warning tone every few seconds. When power becomes too low for the phone
to operate, it automatically turns off. Recharge the battery as soon as
possible.
Note: Rechargeable batteries last longer and perform better if allowed to
fully discharge occasionally. You can do this by leaving the phone
on until the phone automatically turns off or you can use the bat-
tery discharge feature of any approved accessory available for your
phone. Do not try to discharge the battery by any other means.
Installing A Fresh Battery During A Call
If you have an extra charged battery and the currently installed battery
becomes low during a call, follow these steps to change the battery without
ending the call or losing the connection.
1. Tell the other party on the line what you plan to do (tell them, for
example, that they will hear some noise as you remove the battery, and
you will call back if you accidentally lose the connection).
2. Remove the battery, and within 5 seconds, install the fresh battery
than press PWR. Your call is still on the line.
Note: If you are unable to complete Step 2 within 5 seconds, the call
disconnects.
Important Battery Tips
Use only the supplied charger and use only batteries designed for this
phone.
You can purchase additional standard or extended capacity batteries through
your local RadioShack store.
When you are not using the charger, disconnect it from power. Do not leave
the battery connected to the charger and AC power for more than 24 hours,
since overcharging could shorten the battery's life.
When the battery is not in use, store it uncharged in a cool and dark
place.
The battery is a sealed unit with no serviceable parts. Do not try to open
the case.
For the best results, be sure the battery is at or near room temperature
when you charge it.
A battery can be charged and discharged hundreds of time, but it eventually
wears out. When the operating time (talk time and standby time) is notice-
ably shorter than normal, get a new battery and recycle or properly dispose
of the old one.
Do not dispose of batteries in a fire.
Never use any charger or battery that is damaged or worn out.
