Use Technical Specification ISO/TS 21609 (Road
Vehicles – "EMCs for installation of aftermarket
radio frequency transmitting equipment") when
retrofitting two-way radios. Comply with the
legal requirements for detachable parts.
If your vehicle has installations for two-way radio
equipment, use the power supply and antenna
connectors provided in the pre-installation. Be
sure to observe the manufacturer's supplements
when installing.
Two-way radio transmission output
The maximum transmission output (PEAK) at the
base of the antenna must not exceed the values
in the following table.
Frequency band and maximum transmission
output

sion output
Short wave
3 - 54 MHz
(100 W)
