POWERING THE CB
You can power your THC-238 trom any
at these sources:
- Nine AA alkaline batteries (not sup-
plied) wiih the one supplied dummy
batteries
- Tun rechargeable AA nickel-
cudmtum batteries (not supplied)
- Standard AC power (using an op-
tlenal tween Dc adapter)
~ Vchlclu battmv power (using an op-
tionoltas-vott power nerd)
llViPOFtTANT INFORMATION
ABOUT THE POWER JACK
The THC-238 has a slide switch (NI-CD!
ALKALlNE) inside the battery compart-
ment that lets you set the POWER jack to
provide power to the THC-238 or charge
the rechargeable batteries in the battery
compartment.
NI-CDI
ALKALINE
Switch
It Is important that you properly set NI-cD/
) ‘- ALKALINE before you connect any power
device to the POWER lack:
- Set it to ALKALINE before you conv
. nest on external power source (AC
outlet or vehicle battery power). This
disconnects the internal batteries.
. Set it to nl-co only when you can-
nect a battery charger to the POWER
jack to charge installed rechargeable
batteries.

Warning: To avoid injuring yourself or
damaging the THC—238. connect a
battery charger to the PowEnjack only
when nickel-cadmium batteries are In-
stalled (see “Recharging Nickel-Cad-
mium Batteries“ an Page 9), Never try .
to recharge non-rechargeable batteries. r
They could get very hot and explode.
Note: You can connect an external power
source to the POWER jack. regardless of
the type of batteries you install.
USING BATTERIES
You can power the TRC~238 from nine
AA alkaline batteries (such as Fla-
dioShack Cat. N04 23-552) with the me
supplied dummy batteries, or ten re-
chargeable AA nickel-cadmium batteries
(such as Cat No. 23-125).
‘ ‘ v’ Cautions: ‘ {I}
- Always use fresh, or lreshly charged.
batteries of the required size and

PREPARATION
Your walkle-talkie comes with a helical ' " ""
antenna that is ideal lor most applications.
However, the walkie-tfllkie's BNC anten-
na connector makes it easy to connect
other typos of antennas, too. See “Con-
necting an Optional Antenna.‘
CONNECTING THE
FLEXIBLE ANTENNA
Follow these steps to connect the sup-
plied antenna.
u}
1. Position the antenna’s connector
over thelANT jack on the walkie-
talkie,
2. Slide the slot in the antenna connec-
tor over the antenna jack’s tab on top
or the walkio~talkia
3. Press down and turn the antenna's
base clockwise until it locks into
place,

When deciding on a mobile or base-

the lollowing: ‘
~ The antenna should be mounted as
high as possible.
' The antenna and antenna cable
should be as tar as possrble Irorn
sources of electrical noise (applianc-
es, ignition systems, gauges, and so
on)
- The antenna should be vertical tor
the best performance.
When connecting an optional antenna. el—
woys use 50-ohm coaxial cable. such as
HG-SB or HG-B. For lengths over 50 feel,
use HG»8 low-loss dielectric coaxial ca-
bio. ll tho coaxial cable's connector does
not ht on the THC-2138's antenna jack, you
might also need a PL-259—to-BNC anten-
na plug adapter, such as Cat No. 278-
120. 613
Your local FladioShack store carries a
wide variety of coaxial antenna cable and
connectors.
Follow the mounting instmctions supplied
with the antenna. Then route the antenna
cable to the THC-238. and connect it to
the AMT luck on the top of the THC-238
(see "Connecting the Flexible Antenna"
on Page 14).
Cautlons:
._ - Do not run the cable over sharp edg-
es or moving parts.
- Do not run the cable nek‘t to power

l (P '
' Camping. fishing, and other sports
are more iun with a CB radio, Locate
a lrlend or find out "what's cooking"
back at camp.
C B COU RTESY
~ Wait lor a pause in someone eise's
transmission beiore you ask (or a
break.
- it you do not receive an answer to
your call atter a second attempt, sign
oil and wait severai‘minutes betore
trying again, 1
0 D0 nol hold down the transmit button
when you are not talking. (This is
called dead keying.)
- Aesisi callers with directions, intor~
matiun about road conditions. and
\ any other reasonable requests. 11
MAXIMUM RANGE
The maximum range and quality of CB
transmissions vary depending on Ihese
conditions: t
- Amount of power in the batteries
- The surrounding terrain — moun-
tains and tall buildings limit the range
~ Weather conditions
- The number of nearby CBs operal-
ing on ihe same channel
. Standing wave ratio (SWFi) between
the antenna and the OB \
To ensure maximum range. always keep
fresh alkaline batteries or fully charged
nickel—cadmium batteries in your THC-
238 when using battery power.
