(140-0733)                 Preparation                Faxback Doc. # 46892

POWER SOURCES

You can operate the CTR-110 using:

    Internal battery power (using four C batteries)

    AC power (using an optional AC adapter)

    Vehicle battery power (using an optional DC adapter)

Note:  Internal batteries automatically disconnect when you connect an
       adapter.

USING BATTERIES

You can power the CTR-110 from four C batteries (not supplied).  For the
best performance and longest life, we recommend alkaline batteries, such
as RadioShack Cat. No. 230-0551.

1.  Turn the CTR-110 on its face, pull the tabs on the battery
    compartment's cover and remove the cover.

2.  Put four C batteries in the compartment, as indicated by the polarity
    symbols (+ and -) marked inside.

    CAUTIONS:  Use only fresh batteries of the required size and
               recommended type.

               Do not mix old and new batteries, different types of
               batteries (standard, alkaline, or rechargeable), or
               rechargeable batteries of different capacities.

3.  Replace the cover and snap it shut.

If the CTR-110 does not operate properly or if the sound weakens or
distorts, replace the batteries.

CAUTIONS:  Dispose of the old batteries promptly and properly.  Do not
           bury or burn them.

           Never leave dead, old, or weak batteries in the CTR-110.
           Batteries can leak chemicals that can destroy electronic parts.

           If you do not plan to use the CTR-110 from battery power for a
           month or more, or if you plan to use only an adapter, remove
           the batteries to protect the CTR-110 from possible battery
           leakage.

USING AC POWER

You can power the CTR-110 from standard AC power using an optional
AC adapter, such as RadioShack Cat. No. 273-1663.

CAUTIONS:  The recommended AC adapter supplies 6 volts and delivers at
           least 400 milliamps.  Its center tip to set to negative, and
           its plug correctly fits the CTR-110's DC 6V jack.  Using an AC
           adapter that does not meet these specifications could damage
           the CTR-110 or the adapter.

           Always plug the adapter into the CTR-110 before you plug it
           into the AC outlet, and always unplug the adapter from the AC
           outlet before you unplug it from the CTR-110.

1.  Set the AC adapter's voltage switch to 6V.

2.  Insert the AC adapter's 5.5 mm outer diameter/2.1 mm inner diameter
    battery plug into the adapter cord's small end so it reads -TIP, then
    insert the adapter's plug into the DC 6V jack on the back of the
    CTR-110.

3.  Plug the adapter into a standard AC outlet.

Using Vehicle Power

You can power the CTR-110 from your vehicle's battery using an optional
DC adapter, such as RadioShack Cat. No. 273-1802.

CAUTIONS:  The recommended DC adapter supplies 6 volts and delivers at
           least 400 milliamps.  Its center tip is set to negative, and
           its plug correctly fits the CTR-110's DC 6V jack.  Using a DC
           adapter that does not meet these specifications could damage
           the CTR-110 or the adapter.

           Always plug the adapter into the CTR-110 before you plug it
           into the cigarette-lighter socket, and always unplug the 
           adapter from the cigarette-lighter socket before you unplug
           it from the CTR-110.

Follow these steps to use your vehicle's battery.

1.  Set the DC adapter's voltage switch to 6V.

2.  Insert the DC adapter's barrel plug into the CTR-110's DC 6V jack.

3.  Insert the other end of the adapter into your vehicle's
    cigarette-lighter socket.

USING EARPHONES

For private listening, you can connect a pair of earphones (not supplied)
with a 1/8-inch plug.  Your local RadioShack store carries a wide
selection of earphones.

Insert the earphones' 1/8-inch plug into the PHONE jack on the top of the
CTR-110.

Note:  Connecting earphones automatically disconnects the built in
       speaker.

Listening Safely

To protect your hearing, follow these guidelines when you use earphones.

    Set the volume to the lowest setting before you begin listening.
    After you begin listening, adjust the volume to a comfortable level.

    Do not listen at extremely high volume levels.  Extended high volume
    listening can lead to permanent hearing loss.

    Once you set the volume, do not increase it.  Over time, your ears
    adapt to the volume level, so a volume level that does not cause
    discomfort might still damage your hearing.

Traffic Safety

Do not wear earphones while operating a motor vehicle or riding a bicycle.
This can create a traffic hazard and could be illegal in some areas.

Even though some earphones are designed to let you hear some outside
sounds when listening at normal volume levels, they still can present a
traffic hazard.
