Accessories
There are various accessories available for your radio from fastening clips for
attaching the radio to clothing, to headsets and microphones that provide
hands-free operation. Only use Sepura approved accessories with your radio.
Sepura products have been tested to meet strict guidelines for personal safety
and operational conditions. The use of non-approved accessories may damage
the product, will result in the non-compliance with regulatory requirements,
compromise the product safety ratings, and will invalidate the product
warranty.
Caution: Some accessories may not work in close proximity of a TETRA
radio. When using USB and BT accessories, it is recommended that they
are worn on the opposite side of the body to the radio. It is the
responsibility of the service provider to ensure that appropriate EMC
testing has been conducted on accessories.
When your radio powers on and when you attach an accessory during
operation, your radio performs an authenticity check on any attached
accessories including the battery. If the accessory is not authenticated, a
message appears and the accessory should be removed.
Your radio has two connectors for attaching accessories. The rugged
accessory connector (sRAC) on the side of the radio is used for attaching
accessories such as a remote speaker microphone (RSM), headsets and
earpieces. At the bottom of the radio is the digital audio connector (sDAC)
that is used for attaching car kits, data accessories and chargers. It is also used
for programming the radio.
Caution: When using an RSM with antenna, it should be held a
minimum distance of 25 mm from the mouth.
Always refit the cover to the sRAC when an accessory is not in use.
You do not need to power down the radio before fitting or removing an
accessory.
