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.
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 base 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.
Always refit the cover to the sRAC when an accessory is not in use.
You do not need to power down the radio before attaching or removing an accessory.
Always read the instructions supplied with the accessory for operating instructions and safety
information.
Accessory profiles
Your radio may be customised with up to 15 accessory profiles. Selecting a profile that matches the
attached accessory will provide optimum audio quality speech and volume when the accessory is in
use. It is not necessary to select a profile, however, if a profile is not selected or the accessory is not
supported, the audio may not be of optimal quality.
The profile is only applied when the accessory is in use.
Selecting a profile when attaching an accessory
When you attach an accessory, the radio will attempt to match the accessory to a profile. If there is
only one matching profile, the radio will automatically select that profile and there is no user action
required.
If the radio is customised to provide several profiles for an accessory, when the accessory is attached
