2.2 Selecting the Mounting Position
Requirements for 
Safe and Convenient 
Installation
Ensure the mounting position complies with the following safety warnings:
Warning!! Safe radio mounting
■ Mount the radio securely so that it will not break loose in the event of a 
collision. An unsecured radio is dangerous to the vehicle occupants.
■ Mount the radio and the microphone where they will not interfere with:
■ the deployment of passenger airbags
■ the vehicle operator controls
■ the vehicle operator’s view.
Gap Between 
Radio Body 
and Mounting 
Surface
Note It may be necessary to mount the radio upside down to maintain a 
gap of more than 3/8 inch (10mm) between the bottom surface of 
the radio body and the mounting surface. 
Inspect the vehicle and determine the safest and most convenient position 
for mounting the radio. Make sure that there is sufficient clearance behind 
the radio for the heatsink and cables.
IP54 Protection 
Class Considerations
The radio fulfils the requirements of the IP54 protection class.
Important However, do not mount the radio in areas where it can be 
temporarily submerged from an accumulation of water or 
other liquids (e.g. when using a high-pressure 
cleaning device).
The IP54 protection class does not apply when:
■ the control head is removed from the radio body
■ the bungs are removed from the auxiliary connector or the cavity for the 
external options connector (fitting an auxiliary connector or external 
options connector will not restore the IP54 protection class)
■ the microphone grommet is not installed.
