Installer Setup Mode
The T6590 is delivered with a set of pre-configured operational values that will allow the device to function immediately. However, in order to make the device compatible with a specific system, some of the internal settings may need to be changed. For information on the default values and the configurable options, please refer to the “Installer Parameter Table”.
-
To enter the Installer Setup Mode, press the ( ) and buttons together for 3 seconds.
-
To index between the individual Parameters, use the ( ) button. It is only possible to move upwards through the parameters.
-
To change a selected parameter, use the or button.
-
To save the altered settings, exit the Installer Setup Mode by Pressing the ( ) and buttons together for 3 seconds. NB: If the Installer Setup Mode is exited by time-out (approximately 120 seconds), then the newly changed values will not be saved.
