PREPARATION
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 batter-
ies, such as RadioShack Cat. No. 23-
551.
1. Turn the CTR-110 on its face,
pull the tabs on the battery com-
partment’s cover and remove
the cover.
2. Put four C batteries in the com-
partment, as indicated by the
polarity symbols (+ and –)
marked inside.
Cautions
:
• Use only fresh batteries of the
required size and recom-
mended type.
• Do not mix old and new bat-
teries, different types of bat-
teries (standard, alkaline, or
rechargeable), or recharge-
able 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. Batter-
ies can leak chemicals that can
destroy electronic parts.
