INSTALLATION
If you intend to use our
Bluetooth® adapter kit
install the extension cable provided with the kit. Refer to the Bluetooth®
instructions
Mount the radio in the dash using the two 1/2” shaft nuts. Take care not to cross-thread or over-tighten them. Finger tight plus ½ turn
is enough. The radio should also be supported with the 9” backstrap supplied. The control shafts alone cannot suppoort the weight of
the speakers It should bolt to the ¼ 20 stud on the back of the radio and can be bent to fit the mounting bolt under the dash for the
original radio.
DIAGNOSTICS
No Sound:
Check for a good fuse with proper rating. When the radio is turned on, the orange wire should have 12 volts present. Radio
will mute when no station is received. Make sure antenna is plugged into the proper jack. If an option is plugged in, make sure it’s not
on. Before installation make sure the switch on the back of the radio is set for the correct speaker option and country.
Weak or No Reception:
Check continuity between the center pin of the antenna plug and the antenna mast. It should read 0 ohms
(like a short) Next, check continuity between the center pin of the antenna plug and the car body. It should not read (like an open
circuit). If you’re in a metal building, reception may be limited. Try it outside
.
Ignition Noise:
Usually caused by an ungrounded antenna shield. The base of the antenna must make good contact with the car body.
This problem often shows up after a good paint job! Make sure the engine grounding straps are in place, clean and tightly bonded to
the frame.
Distortion:
Check to see if your speakers can handle at least 45 watts RMS. Small speakers that can only reproduce high frequency
will distort on bass notes. Make sure speakers are properly installed. Make sure that no speaker is grounded. Every speaker lead
should measure about 6 volts to ground with the radio on and volume low. Resistance in the DC power input wiring can cause the
amplifiers to “starve”. If distortion seems to increase with volume, measure the voltage on the orange wire. If the voltage drops when
the volume is raised, it is an indication of resistance between the battery and the radio – usually at the fuse block, but sometimes in the
ignition switch. If the backstrap is not bolted to a clean metal ground, try running a heavy ground wire from the ground lug on the
radio directly to the firewall.
Radio shuts off after a few minutes:
The radio has thermal protection built in to prevent damage from excessive heat. Possible
causes are shorted or grounded speaker wires. See if any unused wires can touch anything. Make sure the heater or defroster duct isn’t
blowing directly on the radio.
Dial pointer issues:
If the dial pointer gets stuck at one end or if it is misaligned, hold down one of the 5 preset buttons for 5-10
seconds to realign or free dial pointer. If the dial pointer is stuck at one end of the dial, turn the tuning knob. The dial pointer should
try to move while you're turning the knob. Continue to turn the tuning knob until the pointer resets itself.
