1. If the backlight is set to sleep mode, the white backlight will still illuminate after switch operation even if the operation is stopped.
2. During a parameter error alarm, the LED blinks faster (intervals of 100 ms) than is normal for other alarms (intervals of 250 ms).
3. Transmitter outputs may become erratic in the event of transmitter failure.
4. The orange backlight remains on for 5 minutes after an alarm, or for the sleep duration of the backlight. After this time, the orange backlight will blink on and off.
