Ground Connection
Locate a strong spot in the metal near the transceiver to connect the ground lead. A good mechanical connection of the ground lead is vital,
since a bad connection may cause the transceiver to locate poorly and behave erratically. Scrape away any paint or coating on the metal
where the ground will be attached, and then use a star washer between the metal and the ground terminal.
Vehicles with aluminium and fibreglass bodies require special handling. Oxidation and electrolysis create problems with aluminium bodies,
and fibreglass does not conduct current. In these cases, run the lead to the battery and connect it to the negative side.
We recommend not using the existing factory wires attached to ground; this could cause interference or noise. It is noted that the TM470
performance will be seriously degraded.
