INSTALLATION INSTRUCTIONS
Using the Mounting Sleeve
1. Slide the mounting sleeve off the chassis. If
it is locked into position, use the removal
tools (supplied) to disengage it.
2. Check the dashboard opening size by sliding the mounting sleeve into it.
If the opening is too small, carefully cut or
file as necessary until the sleeve easily
slides into the opening. Do not force the
sleeve into the opening or cause it to bend
or bow. Check for sufficient space behind
the dashboard for the radio chassis.
3. Locate the series of bend tabs along the top,
bottom, and sides of the mounting sleeve.
With the sleeve fully inserted into the dashboard opening, bend as many of the tabs
outward as necessary to firmly secure the
sleeve to the dashboard.
4. Place the radio in front of the dashboard
opening so the wiring can be brought
through the mounting sleeve. Follow the wiring diagram carefully and make certain all
connections are secure and insulated with
wire nuts or electrical tape. After completing
the wiring connections, turn the unit on to
confirm operation (vehicle ignition must be
on). If the unit does not operate, re-check all
wiring until the problem is corrected.
5. Make sure the radio is right-side up, then
carefully slide the radio into the mounting
sleeve until it is fully seated and the spring
clips lock it into place.

6. Secure the rear of the unit to the car body
using the mounting bolt and rubber cushion.

Installation Using a Kit
If your vehicle requires the use of an installation
kit to mount this radio, follow the instructions
included with the installation kit to attach the
radio to the mounting plate supplied with the kit.
1. Wire and test the radio as described in step
4 of “Using the Mounting Sleeve”.
2. Install the radio mounting plate assembly to
the sub-dashboard according to the installation kit instructions.
3. Attach the support strap to the radio and
dashboard as described in step 6 of “Using
the Mounting Sleeve”.
4. Replace the dashboard trim panel.
ISO Installation
This unit has threaded holes in the chassis side
panels which may be used with the original
factory mounting brackets of some Toyota,
Nissan, Mitsubishi, Isuzu, Hyundai and Honda
vehicles to mount the radio to the dashboard.
Please consult with your local car stereo
specialty shop for assistance on this type of
installation.
1. Remove the existing factory radio from the
dashboard or center console mounting.
Save all hardware and brackets as they will
be used to mount the new radio.
ISO INSTALLATION
2. Carefully unsnap the plastic frame from the
front of the new radio chassis. Remove and
discard the frame.
3. Remove the factory mounting brackets and
hardware from the existing radio and attach
them to the new radio.
CAUTION: Do not exceed M5 X 6 MM screw
size. Longer screws may touch and damage
components inside the chassis.
4. Wire the new radio to the vehicle as
described in step 4 of “Using the Mounting
Sleeve”.
5. Mount the new radio assembly to the dashboard or center console using the reverse
procedure in step 1 of “Using the Mounting
Sleeve”.
Removing the Radio
To remove the radio after installation, remove
the trim ring by lifting in the center and pulling it
off from either side. Insert the removal keys
straight back until they lock, then pull the radio

CARE AND MAINTENANCE
UMP401
Your new radio/CD player does not require any
maintenance. However, proper understanding
of its use and handling will help you obtain
maximum enjoyment of its capabilities. We
recommend that you keep this manual for
reference on the many features of this unit as
well as how to set the clock. The following
points should be observed:
•When cleaning the interior of the vehicle, do
not get water or cleaning fluids on the unit.
•The CD player is a precision instrument and
will not operate properly in extreme heat or
cold. If such conditions occur, wait until the
interior of the vehicle reaches a normal
temperature before using the player.
•If the temperature inside the player gets too
hot, a protective circuit will automatically
stop play of the disc. In this case, allow the
unit to cool before operating the player
again.
•Never insert anything other than a 5" (12
cm) compact disc into the player as the
mechanism can be damaged by foreign
objects.
•Do not attempt to use 3" (8 cm) CD-Single
discs in this unit, either with or without an
adaptor, as damage to the player and/or disc
may occur. Such damage will not be covered
by the Warranty on this product.
•When not using the disc player, always
remove the compact disc. Do not leave an
ejected disc sitting in the disc slot as this can
expose it to sunlight and other causes of
damage.
•Do not attempt to open the unit chassis.
There are no user-serviceable parts or
adjustment points inside.
•When the vehicle warms up during cold
weather or under damp conditions,
condensation may appear on the lens of the
disc player. Should this occur, the player will
not operate properly until the moisture has
evaporated.
•The unit is designed with a vibration
dampening CD mechanism to minimize
interruption of disc play due to normal
vibration. When driving on rough roads,
however, occasional sound skips may occur.
This will not scratch or damage the disc and
normal play will resume when the rough
conditions cease.
Handling Compact Discs
Dirt, dust, scratches and warping can cause
skips in the playback and deterioration of sound
quality. Please follow these guidelines to take
care of your compact discs:
•Carefully wipe fingerprints, dust and dirt from
the disc’s playing surface with a soft cloth.
Wipe in a straight motion from the center to
the outside of the disc.
•Never use chemicals such as record sprays
or household cleaners to clean CDs, as they
can irreparably damage the disc’s surface.
•Discs should be kept in their storage cases
when not in use.
