TRC-237 40-Channel 5-Watt CB Walkie Talkie
(210-1650) Power Faxback Doc. # 51773
Powering The CB
You can power your TRC-237 from any of these sources (none supplied):
Eight AA alkaline batteries with the two supplied dummy batteries.
Ten rechargeable AA nickel-cadmium batteries.
12-volt vehicle battery power using a fused power cord.
Standard AC power using a power supply.
Using The Power Jack And Alkaline/Ni-Cd Switch
The POWER jack lets you connect an external power source (such as your
vehicle's battery power or AC power), or connect a battery charger to
charge nickel-cadmium batteries while they are in the TRC-237.
The TRC-237 also has a slide switch (ALKALINE/NI-CD) inside the battery
compartment that you must set correctly, depending on what power source
you are using and whether or not you want to charge rechargeable batteries
while they are in the TRC-237.
Set it to ALKALINE before you connect an external power source (vehicle
battery power or AC adapter) to the POWER jack or while you are using
internal batteries (alkaline or rechargeable).
Set it to NI-CD only when you connect a battery charger to the POWER
jack to charge the installed rechargeable batteries.
WARNING: To avoid injuring yourself or damaging the TRC-237, connect a
battery charger to the POWER jack only when nickel-cadmium
batteries are installed (see "Recharging Nickel-Cadmium
Batteries," below). Never try to recharge non-rechargeable
batteries. They could get very hot and explode.
Note: You can connect an external power source for power regardless of
the type of batteries you installed.
Using Batteries
You can power the TRC-237 from eight AA alkaline batteries (such as
RadioShack Cat. No. 23-552) with the two supplied dummy batteries, or 10
rechargeable AA nickel-cadmium batteries (such as Cat. No. 23-125).
CAUTIONS: Always use fresh, or freshly charged, batteries of the required
size and recommended type.
Do not mix old and new batteries, different types of batteries
(standard, alkaline, or rechargeable nickel-cadmium), or
rechargeable batteries of different capacities.
Follow these steps to install the batteries.
1. If the TRC-237 is on, turn OFF/VOLUME fully counterclockwise until it
clicks to turn it off.
2. Slide the strap on the back of the TRC-237 through the buckle and the
battery compartment cover to remove it.
3. Slide the battery compartment cover in the direction of the arrow to
remove it.
4. Be sure ALKALINE/NI-CD inside the battery compartment is set to
ALKALINE.
5. Put eight AA alkaline batteries and the two supplied dummy batteries,
or ten AA nickel-cadmium batteries into the battery compartment, as
indicated by the polarity symbols (+ and -) marked inside.
Note: Before you use the TRC-237 with nickel-cadmium batteries, you
need to charge the batteries, (see "Recharging nickel-cadmium
Batteries," below).
6. Replace the battery compartment cover and the strap on the back of the
TRC-237.
CAUTIONS: If you will not be powering the TRC-237 from internal batteries
for several months, remove the batteries.
Dispose of old batteries promptly and properly.
Testing the Battery Power
1. Turn on the TRC-237 by rotating OFF/VOLUME clockwise until it clicks.
2. Hold down BATT TEST. If the indicator lights, there is enough battery
power to operate the CB. If the indicator is dim or does not light,
replace or recharge the batteries.
Recharging Nickel-Cadmium Batteries
You can use a battery charger, Cat. No. 23-249 (not supplied), to charge
or recharge nickel-cadmium batteries while they are inside the TRC-237's
battery compartment.
Do not use the TRC-237 while you are charging the nickel-cadmium batteries
CAUTIONS: Use only the recommended battery charger to recharge the
batteries in the TRC-237. Other chargers could damage your
TRC-237 or the batteries.
Be careful not to overcharge nickel-cadmium batteries.
To prevent damage to rechargeable nickel-cadmium batteries,
never charge them in an area where the temperature is above 90
degrees F (32 degrees C) or below 40 degrees F (4.5 degrees C).
Follow these steps to charge nickel-cadmium batteries in the TRC-237.
1. If the TRC-237 is on, turn OFF/VOLUME fully counterclockwise until it
clicks to turn it off.
2. Set ALKALINE/NI-CD inside the battery compartment to NI-CD (see "Using
the Power Jack and ALKALINE/NI-CD Switch," above).
3. Connect the battery charger's 5.5 mm outer diameter. /2.1 mm inner
diameter barrel plug to the POWER jack on the side of the TRC-237,
then plug the battery charger's plug into a standard AC outlet.
It takes about 24 hours to charge new or fully discharged nickel
cadmium batteries. Subsequent charges take about 16 to 18 hours.
4. When charging is complete, unplug the battery charger's plug from the
AC outlet. Then disconnect the battery charger's barrel plug from the
POWER jack.
5. If the TRC-237 is on, turn OFF/VOLUME fully counterclockwise until it
clicks to turn it off. Then set ALKALINE/NI-CD to ALKALINE.
Note: You can use an external charger (such as Cat. No. 23-134, not
supplied) to recharge the nickel-cadmium batteries. After removing
the batteries from the TRC-237, follow the instructions that come
with the external charger.
IMPORTANT: Your TRC-237 is capable of using nickel-cadmium batteries. At
the end of the batteries' useful life, they must be recycled
or disposed of properly. Contact your local, county, or state
hazardous waste management authorities for information on
recycling or disposal programs in your area. Some options that
might be available are: municipal curbside collection, drop
off boxes at retailers such as your local RadioShack store,
recycling collection centers, and mail-back programs.
Using Vehicle Battery Power
You can power your TRC-237 from your vehicle's cigarette-lighter socket
with an optional 12-volt DC fused power cord (such as Cat. No. 270-1533).
CAUTIONS: You must use a DC fused cord that supplies 12 volts and
delivers at least 1200 milliamps of vehicle power. Its center
tip must be set to positive, and its plug must correctly fit
the TRC-237's POWER jack. The recommended fused cord meets
these specifications. Using a fused cord that does not meet
these specifications could damage the TRC-237 or the fused cord.
When you finish using the TRC-237, unplug the fused cord from
the cigarette-lighter socket before you disconnect it from your
TRC-237.
1. If the TRC-237 is on, turn OFF/VOLUME fully counterclockwise until it
clicks to turn it off.
2. Be sure ALKALINE/NI-CD inside the battery compartment is set to
ALKALINE.
3. Insert the power cord's 5.5 mm outer diameter/2.1 mm inner diameter
barrel plug into the POWER jack.
4. Plug the power cord's other end into your vehicle's cigarette-lighter
socket.
Note: If the TRC-237 does not operate when you use the DC power cord,
unplug the cord from the cigarette-lighter socket and clean any
ashes or debris from the socket. If your TRC-237 still does not
work, check the fuse in the DC power cord and replace it if
necessary.
Using AC Power
You can power your TRC-237 from standard AC power using an optional AC-to
12 V DC power supply (such as Cat. No. 22-504) and an optional DC fused
power cord (such as Cat. No. 270-1533).
CAUTIONS: The power supply must be able to deliver 12 volts and at least
1200 milliamps of power. The recommended power supply meets
these specifications. Using a power supply that does not meet
these specifications could damage the TRC-237 or the power
supply.
You must use a DC fused cord that supplies 12 volts and
delivers at least 1200 milliamps of power. Its center tip must
be set to positive, and its barrel plug must correctly fit the
TRC-237's POWER jack. The recommended fused cord meets these
specifications. Using a fused cord that does not meet these
specifications could damage the TRC-237 or the fused cord.
To help prevent an electrical short, unplug the DC fused cord's
plug from the AC adapter's power socket before you unplug the
cord's barrel plug from the TRC-237.
Follow these steps to connect the TRC-237 to AC power.
1. If the TRC-237 is on, turn OFF/VOLUME fully counterclockwise until it
clicks to turn it off.
2. Connect the DC fused cord's 5.5 mm outer diameter/2.1 mm inner
diameter barrel plug to the TRC-237's POWER jack.
3. Be sure ALKALINE/NI-CD inside the battery compartment is set to
ALKALINE.
4. Plug the DC fused cord's other end into the power supply's power
socket.
5. Plug the power supply into a standard AC outlet, then turn on the
power supply.
Note: If the TRC-237 does not operate when you use the DC fused cord,
turn the power supply off, unplug the cord from the power supply's
power socket then clean any debris from the socket. If your TRC-237
still does not work, check the fuse in the DC fused cord and
replace it if necessary.
