SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on
schematics or by special notes in the part lists. Use only replacement parts that
have critical characteristics recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed
parts are acceptably insulated from the supply circuit before returning the unit
to the customer. Use the following checks to perform these measurements:
A. Leakage Current Hot Check: With the unit completely assembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a
leakage current tester or a metering system that complies with American National Standards
Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL)
813. With the unit's AC switch first in the ON position and then in the OFF position, measure
from a known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the
unit (antennas, handle bracket, metal cabinet, screw-heads, metallic overlays, control shafts,
etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any
current measured must not exceed 0.75 milliamp. Reverse the unit's power cord plug in the
outlet and repeat the test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED
HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check: (1) Unplug the power cord from the wall outlet
and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of
the unit. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and
each exposed metallic cabinet part on the unit. The reading should be between infinite. When
there is no return path to the chassis, the reading must be "infinite". If it is not within the limits
specified, there is the possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned to the customer.
ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)
DEVICE HANDLING
This unit contains ESDS devices. We recommend the following precautions when repairing,
replacing or transporting ESDS devices:
• Perform work at an electrically grounded work station.
• Wear wrist straps that connect to the station or heel straps that connect to conductive floor
mats.
• Avoid touching the leads or contacts of ESDS devices or PC boards even if properly
grounded. Handle boards by the edges only.
• Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert
unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags,
bubble wrap or plastic trays.

If a pre-installed speaker system is connected to the Zone 2 amplifier and it measures less
than 3.2 Ω (DC resistance), add resistors according to the table below before operating the
system. This will prevent the amplifier's short circuit protection from activating during loud
music. If the pre-installed speaker system measures less than 2.20 Ω, the speaker system
must be rewired for higher resistance. This can be achieved by wiring the individual speakers
in series or in a series parallel combination instead of all in parallel.

TROUBLESHOOTING TIPS
1. The amplifier fault protection circuit can trip causing no audio output. To reset the Zone 1
and 2 amplifier fault protection circuit, turn off the power switch located in the rear of the unit,
wait five seconds and the turn-on the power switch.
2. Disconnect the power to the Jukebox. Open the rear panel and make sure that all the
connectors to the amplifier module and the I/O PCB are fully inserted. Close the back panel
and apply power to the Jukebox. If the Jukebox still does not operate properly, disconnect the
power from the Jukebox and perform the following procedures to isolate the failure.
3. Check the fuse that is located on the equalizer PCB (top PCB). See Figure 4 and procedure
5 in the disassembly/assembly section.
4. Disconnect the ZONE 1 or ZONE 2 transformer and measure the DC resistances of the
transformer primary (J7). It should be approximately 1.4 Ω. Replace the transformer if the
resistance is out of range.
5. If the transformer measures good, swap the ZONE 1 and ZONE 2 DIN input cable (J5). If
the problem switches (i.e. ZONE 1 has output now and ZONE 2 has no output) the problem is
with the I/O PCB. Replace the I/O PCB.
6. If the problem does not switch when the DIN input cable is swapped between ZONE 1 and
ZONE 2 and the problem is with ZONE 1, disconnect the woofer output cable (J3) from the
ZONE 1 amplifier module. Measure the DC resistance between the black and red wire. It
should be 5.3 Ω. If the DC resistance is out of range, a woofer is defective. Remove each
woofer and check its DC resistance. Each woofer should measure 5.3 Ω. Replace the defective woofer(s).
7. If the DC resistance of the woofer measures good, disconnect the RCA plugs (J9) from the
amplifier module. Measure the DC resistance between the tip and sleeve of the RCA plug (red
and white). It should be 2.8 Ω. If it measures out of range, remove the 141
measure the DC resistance of each speaker (right side only if the red RCA plug is out of range,
left side only if the white RCA plug measures out of range). Each speaker should measure
1.4 Ω. Replace the defective 141JB speaker(s).
8. If the failure is not identified using procedures 1 through 6, the problem is with the amplifier
module. Replace the amplifier module.
