Troubleshooting; Automatic Volume Control (Avc) - Biketronics BT1000 Instructions Manual

 It is UNSAFE to look at the radio while riding. Familiarize yourself with radio controls in the
garage. Allow yourself time to normalize working the radio with hand controls and "hearing"
the results.
 Sony radios have a beep that is emitted when control input is given. Keep this feature
enabled until you are acclimated to operating the radio without looking at the radio face.
 For handle-bar radio controls to operate, the ⅛" L-shaped plug on Black cable (item #1,
photo #5) must be firmly plugged in back of radio with Black cable pointed straight up
toward windscreen.
 There are 2 fuses (radio memory and radio power) in Harley harness that must be operable
for radio to turn on (lights on). There is a third fuse located in rear of radio.
 (1997-2011) - 2 fuses are located behind side cover on kickstand side of Harley.
 (1996) - 2 fuses are located in fairing below radio and both must be changed to a 5 or
10 amp rating for radio to operate. Do not exceed 10 amp rating.
 There is a Harley (1998-2005) OEM radio ground wire located on kickstand side of top triple
tree cast iron clamp. This ground wire (Black/green stripe) is attached on top surface with a
spade connector that can become disconnected and create a dead circuit.
 Radio sound can be greatly enhanced by the use of tone and equalizer bands. Consult radio
instruction manual to access these functions.
 If handle-bar radio controls start to operate erratically, disconnect negative battery cable
from Harley battery for 5 minutes and reconnect. If the problem still persist call Biketronics
for assistance.
 Addition of separate ground wire between radio and bike frame can cure erratic handle-bar
controls of radio. Radio has bolt hole (metric M4 x ½" bolt) in rear of unit for ground point.
Biketronics module comes from factory with AVC setting of 2 for normal operation
If you wish to change the setting - perform the following steps:
 Turn on radio to start AVC programming.
 AVC information WILL NOT display on radio face.
 Follow "SET AVC" procedure on page 9.
 The only method to verify successful AVC programming is to ride bike and verify that radio
volume varies with speed.
 Tips and suggestions -
 Harleys can experience problems due to corrosion/age/modifications that may effect
normal operations of handle-bar radio control buttons.
 Set AVC – step #2 (page 9): Automatic volume control depends on # of pushes of LEFT
handle-bar radio control button. 1 push = fastest volume gain, 20 pushes = slowest
volume gain, 0 pushes = AVC turned off. Typical setting is usually 2 – 7 pushes of LEFT
handle-bar radio control button.
 Left handle-bar radio control buttons – radio volume, tone & balance, AVC programming.
 Right handle-bar radio control buttons - radio seek/scan, presets & source/mode.
 Harley ignition must be turned on for radio to operate.
