NOISE FILTER ACCESSORY
As mentioned previously the Noise Filter accessory should be used when your Two Way
Radio is powered by the motorcycle battery and/or your Two Way Radio is connected to an
external antenna to extend Two Way radio range. Using the Noise Filter Accessory prevents
the transmission of conductive noise from the motorcycle through the BikerCom system.
The Noise Filter accessory is sold separately and not included in the BikerCom package
contents. To purchase the Noise Filter accessory first contact the original place of purchase,
alternatively you can contact an authorised distributor in your region or the manufacturer.
When using the Noise Filter Accessory the Push To Talk button must be connected to the
Noise Filter even if a two way radio is not being used; when the Noise Filter accessory is in
use only the Push To Talk button can be used for Powering On and Off the Control Box.
To use the Noise Filter accessory complete the following steps:
1. Connect the Noise Filter accessory lead labeled Power to the Power Cable with Fuse
which is connected to the motorcycle battery.
2. Connect the Noise Filter accessory lead labeled Control Box to the Control Box.
3. Connect the Noise Filter accessory lead labeled Power Adapter to the Two Way Radio
charging/power adapter.
4. Connect the Noise Filter accessory lead labeled PTT to the Control Box socket labeled
PTT; this is a dual lead, insert the 2.5mm pin.
5. Connect the Noise Filter accessory lead labeled PTT to the Push To Talk button; this
is a dual lead, insert the Push To Talk button 2.5mm pin.
 Proceed with standard BikerCom setup.
