Cypress OTT-2100 Manual - Status LEDs
LED 1
LED 2
LED 3
The OTT-2100 has three RGB LEDs that show the status of the device. The LED displays are
di
ff
erent, depending on the operating mode the unit is in. There are LED tables showing the states
and meanings of the three LEDs in each of the operating mode sections of this manual. When the
device is powered on in any mode, LED 2 (center) will display the power up sequence. LED 2 will
briefly flash red, then green, then blue. See the LED tables in the COMSET Mode, Listening Mode,
and Firmware Update Mode sections for specific LED behavior in each mode.
In COMSET Mode, Listening Mode, and Firmware Update Mode LED 1 will be solid red when the
battery voltage is low.
Sleep Mode
The OTT-2100 enters Sleep Mode when none of the switches have been used for more than 2.5
minutes (150 seconds). The OTT-2100 exits Sleep Mode when it is power cycled by moving the
Power/Mode switch to the center position and then to the left or right position. The purpose of
Sleep Mode is to save battery life.
