Notes on technical data

You should have all work on electrical

and electronic components carried out

at a qualiꢀed specialist workshop.

When operating two-way radios in the

vehicle, always connect them to the low-

reꢁection exterior antenna.

NOTE Mercedes-AMG vehicles

Observe the notes in the Supplement.

You could otherwise fail to recognize

dangers.

WARNING Risk of accident due to

NOTE Invalidation of the operating permit

due to failure to comply with the instruc-

tions for installation and use

improper operation of two-way radios

If you use two-way radios in the vehicle

improperly, their electromagnetic radiation

can disrupt the vehicle's electronics. This is

the case in the following situations, in particu-

lar:

The data stated only applies to vehicles with

standard equipment. You can obtain further infor-

mation from an authorized Mercedes-Benz Cen-

ter.

The operating permit may be invalidated if the

instructions for installation and use of two-way

radios are not observed.

Only use approved frequency bands.

Observe the maximum permissible out-

put power in these frequency bands.

The two-way radio is not connected to an

exterior antenna.

The exterior antenna is installed incor-

rectly or is not a low-reꢁection antenna.

Vehicle electronics

Two-way radios

Only use approved antenna positions.

Notes on installing two-way radios

This could jeopardize the operating safety of

the vehicle.

WARNING Risk of accident due to

improper work on two-way radios

Have the low-reꢁection exterior antenna

installed at a qualiꢀed specialist work-

shop.

If two-way radios are manipulated or retroꢀt-

ted incorrectly, the electromagnetic radiation

from the two-way radios can interfere with the

vehicle electronics and jeopardize the operat-

ing safety of the vehicle.

Technical data

On the rear fenders, it is recommended that you

install the antenna on the side of the vehicle clos-

est to the center of the road.

Use Technical Speciꢀcation ISO/TS 21609 (Road

Vehicles – "EMCs for installation of aꢂermarket

radio frequency transmitting equipment") when

retroꢀtting 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.

Observe the manufacturer's supplements when

installing.
