Using the DC Power Cord
To power the Model 28 from your vehicle’s bat-
tery, plug the supplied DC power cord’s small
plug into the Model 28’s
DC 12V
jack. Then plug
the other end into the vehicle’s cigarette-lighter
socket.
Cautions:
• Do not operate your Model 28 while driving.
• Use only the supplied DC power cord.
• Make sure the ring on the tip of the ciga-
rette-lighter socket is securely screwed in
before you insert it into the vehicle’s ciga-
rette-lighter socket.
• Be sure the cigarette-lighter socket is free
of ashes and other debris.
• Always plug the DC power cord into the
Model 28 before you plug it into the ciga-
rette-lighter socket. Always unplug it from
the cigarette-lighter socket before you
unplug it from the Model 28.
• If you use the Model 28 with the vehicle’s
engine turned off, protect the vehicle’s bat-
tery from completely discharging by run-
ning the engine for a few minutes. Unplug
the DC power cord as soon as you finish
using the Model 28.
Notes:
• When the DC power cord is plugged in,
the AC power cord is automatically dis-
connected. To use the Model 28 with AC
power, disconnect the DC power cord
from the Model 28.
• The fuse supplied with the DC power
cord helps protect your vehicle’s electri-
cal system and the Model 28. For infor-
mation about replacing the fuse, see
“Replacing the DC Power Cord’s Fuse”
on Page 40.

PHONE
jack. This mutes the Model 28’s speak-
er. Your local RadioShack store sells a wide
selection of earphones.
Listening Safely
To protect your hearing, follow these guidelines
when you use an earphone.
• Set the volume to the lowest setting before
you begin listening. After you put on the
earphone, adjust the volume to a comfort-
able level.
• Do not listen at extremely high volume lev-
els. 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.
