Important : Your TRC-236 is capable ofusing nickel-cadmium batteries. At the endof the batteries’ useful life, they must be re-cycled or disposed of properly. Contactyour local, county, or state hazardouswaste management authorities for informa-tion on recycling or disposal programs inyour area. Some options that might beavailable are: municipal curbside collec-tion, drop-off boxes at retailers such asyour local RadioShack store, recycling col-lection centers, and mail-back programs.

USING VEHICLE BATTERY POWER

You can power your TRC-236 from yourvehicle’s cigarette-lighter socket with anoptional 12-volt DC fused power cord(such as Cat. No. 270-1533).

Cautions:

• You must use a DC fused cord thatsupplies 12 volts and delivers atleast 1200 milliamps of vehiclepower. Its center tip must be set topositive, and its plug must correctlyfit the TRC-236’s POWER jack. Therecommended fused cord meetsthese specifications. Using a fusedcord that does not meet these speci-fications could damage the TRC-236or the fused cord.

21-1649.fm Page 12 Thursday, August 5, 1999 11:33 AM

13

• When you finish using the TRC-236,unplug the fused cord from the ciga-rette-lighter socket before you dis-connect it from your TRC-236.

1. If the TRC-236 is on, turn OFF/VOL-UME fully counterclockwise until itclicks to turn it off.

2. Be sure ALKALINE/NI - CD inside thebattery compartment is set to ALKA-LINE.

3. Insert the power cord’s 5.5 mm outerdiameter/2.1 mm inner diameter bar-rel plug into the POWER jack.

4. Plug the power cord’s other end intoyour vehicle’s cigarette-lighter socket.

Note: If the TRC-236 does not operatewhen you use the DC power cord, unplugthe cord from the cigarette-lighter socketand clean any ashes or debris from thesocket. If your TRC-236 still does notwork, check the fuse in the DC power cordand replace it if necessary.

USING AC POWER

You can power your TRC-236 from stan-dard AC power using an optional AC-to-12 V DC power supply (such as Cat. No.22-504) and an optional DC fused powercord (such as Cat. No. 270-1533).

21-1649.fm Page 13 Thursday, August 5, 1999 11:33 AM

14

Cautions:

• The power supply must be able todeliver 12 volts and at least 1200 mil-liamps of power. The recommendedpower supply meets these specifica-tions. Using a power supply thatdoes not meet these specificationscould damage the TRC-236 or thepower supply.

• You must use a DC fused cord thatsupplies 12 volts and delivers atleast 1200 milliamps of power. Itscenter tip must be set to positive,and its barrel plug must correctly fitthe TRC-236’s POWER jack. The rec-ommended fused cord meets thesespecifications. Using a fused cordthat does not meet these specifica-tions could damage the TRC-236 orthe fused cord.

• To help prevent an electrical short,unplug the DC fused cord’s plug fromthe AC adapter’s power socket be-fore you unplug the cord’s barrel plugfrom the TRC-236.

Follow these steps to connect the TRC-236 to AC power.

1. If the TRC-236 is on, turn OFF/VOL-UME fully counterclockwise until itclicks to turn it off.

2. Connect the DC fused cord’s 5.5 mmouter diameter/2.1 mm inner diame-ter barrel plug to the TRC-236’sPOWER jack.

3. Be sure ALKALINE/NI - CD inside thebattery compartment is set to ALKA-LINE.

4. Plug the DC fused cord’s other endinto the power supply’s power socket.

5. Plug the power supply into a stan-dard AC outlet, then turn on the pow-er supply.

Note: If the TRC-236 does not operatewhen you use the DC fused cord, turn thepower supply off, unplug the cord from thepower supply’s power socket, then cleanany debris from the socket. If your TRC-236 still does not work, check the fuse inthe DC fused cord and replace it if neces-sary.

CONNECTING AN OPTIONAL ANTENNA

Your walkie talkie comes with a telescop-ing antenna that is ideal for most applica-tions. However, the walkie talkie’s EXTANTENNA jack makes it easy to connectother types of antennas, too. For mobileor base station use, you might want toconnect an optional external antenna.Your local RadioShack store carries awide selection of external mobile or out-door base-station antennas. Choose theone that best meets your needs.

When deciding on a mobile or base-station antenna and its location, considerthe following:

• The location of the antenna shouldbe as high as possible.

21-1649.fm Page 15 Thursday, August 5, 1999 11:33 AM

16

• The antenna and antenna cableshould be as far as possible fromsources of electrical noise (appli-ances, other radios, and so on).

• The antenna should be vertical forthe best performance.

Note : When connecting an optional an-tenna, always use 50-ohm coaxial cable,such as RG-58 or RG-8. For lengths over50 feet, use RG-8 low-loss dielectric coax-ial cable. If the coaxial cable’s connectordoes not fit into the EXT ANTENNA jack,you might also need a PL-259-to-phonoantenna plug adapter, such as Cat. No.278-208. Your local RadioShack store car-ries a wide variety of coaxial antenna ca-ble and connectors.

Follow the installation instructions sup-plied with the antenna, route the antennacable to the TRC-236, then connect it tothe EXT ANTENNA jack.

Cautions :

• Do not run the cable over sharpedges or moving parts.

• Do not run the cable next to powercables or other CB antenna cables.

• Do not run the cable through a vehi-cle’s engine compartment or otherareas that produce extreme heat.

• Follow all cautions and warningsincluded with the antenna.

21-1649.fm Page 16 Thursday, August 5, 1999 11:33 AM
