Problem:
Not linking with Bluetooth device or Linking with Bluetooth device, but no audio plays.
Troubleshooting:
1. Restart Bluetooth Dock
2. Restart Bluetooth Device
3. Make sure Bluetooth device is in play mode
Warning: Do not adjust the volume all the way up if no audio is present. Doing so could
damage your speakers if audio reconnects.
Problem:
Troubleshooting:
Verify you have connected the CAT5 cable correctly. Follow the TIA-568A
standard at both ends. Mis-wiring can cause distorted sound, prevent the system from
functioning, or possibly cause damage to the components in the system. Verify you have
connected the speakers in phase. Follow the label on the product. Out of phase speakers can
rob the system of its bass, especially when driving dual-voice-coil speakers.
If no audio is heard, check to make sure that the audio source is playing, then press the power
button on the keypad to make sure it is turned on.
Audio quality issues
Problem:
Hum in System
Troubleshooting:
Plug all parts of the system into the same outlet to see if the hum goes away.
Try lifting the ground with a ground lifting plug.
Possible Cause:
The different components in the system are connected to different electrical
grounds. This forces electrical currents to find alternate paths to ground causing an audible
60Hz hum.
Solution:
Plug products into an electrical circuit with a common ground.
Additional Tips:
1. The AB-318 is designed to charge a Micro-USB device.
The device screen should indicate that it is being charged. If this does not occur, make sure
the power is reaching the volume control keypad (press the volume buttons to see if the LED
indicators light up).
2. Observe wiring distance specifications. The maximum recommended wire length
between the wall dock and CAT5 audio hub is 250 feet. Although the AB-318 may work at
greater distances, extreme distances are not recommended because erratic performance
may result due to the power loss caused by the CAT5 wire.
3. If you are experiencing problems with your Micro-USB device that occur even when it is
not docked in the AB-318, then please contact the manufacturer of your device.
NOTE: Maximum charging voltage is 5vDC 500mA. Do not plug in a device such as
a tablet computer to this dock. Doing so can cause damage to either device and will
void the warranty.

Stripping and Connecting CAT-5 Wire
Blade
Cat5
1.
Place the CAT-5 between the blade and the first notch of the J-110 tool.
CAT-5 cable should be stripped with a proper stripping tool, such as Channel
Vision’s J-110 tool.
Slight

Rotate
1 turn only
2.
Rotate the tool only once. Multiple turns
will cause you to cut into the inner wires.
3.
Inspect the inner wires for damage.
If any wires are cut start over at step 1.
