The specification sheet describes a North American version. Confirm the exact regional hardware, supported channel widths and programmed frequencies of the customer radio.
The standard radio is separate from the optional intrinsically safe version described in the document. That option does not establish ATEX certification for this record.
Listed option boards and privacy features are model capabilities. Installed options, keys and network settings must be checked before claiming interoperability.
An optional second-band receive module does not add second-band transmit capability.
