The TKR-850 has the DC Power Save feature. The DC Power Save Mode is activated when the DC Power Save On function is executed.
When the DC Power Save Mode is activated, all panel LEDs except the Power LED are turned off, and the audio amplifier and the DSP becomes inactive.
When the Display On function is executed while the repeater is in the DC Power Save Mode, all panel LEDs become active as normal status indicators on the repeater, and the audio amplifier and the DSP becomes active. However, when the Save Delay Timer A period expires, all panel LEDs except the Power LED are turned off and the audio amplifier becomes inactive again, and when the Save Delay Timer B period expires, the DSP becomes inactive.
When the DC Power Save Mode is turned on or off, up to 3 functions preprogrammed into the Save On function or Save Off function are executed in sequence.
