Select key.
If you change to another accessory whilst operating the radio, the Accessory Profile screen
appears, allowing you to select a new profile or accept the default profile for that accessory
(highlighted). To select the profile, press the Select key.
If you attach a second accessory, such as adding an accessory to an RSM, the Accessory Profile
screen appears and you can select a new profile.
A soft key on your radio may be customised to open the Accessory Profile screen at any time
during operation, allowing you to change the profile to suit your conditions, for example you may
want to select a profile that has a louder volume when working in a noisy environment.
Detecting an accessory at power on
If an accessory is detected when the radio is powered on, and it is the same accessory that was
attached at power off, the radio will continue to operate using the selected profile.
If an accessory is removed and then an accessory of the same type is attached before power on, that
has a different accessory profile, you must remove the accessory and then re-attach it, or press a
customised soft key to open the Accessory Profile screen. You can then select a profile for the
accessory.
