Low Voltage Threshold Warning
This feature is created for APX mobile radio to provide warning for low voltage threshold.
A specific external device is attached to the radio to monitor the automobile voltage. When the car
battery went lower than a pre-defined threshold, the external device asserts the Vehicular Interface
Port (VIP) input to the radio. When the voltage of the battery becomes normal, the external device de-
asserts the VIP input to the radio.
The voltage threshold is customized in the external device settings.
When the VIP switch turns on, the VIP asserts input to the radio. The radio immediately initiates a 15
seconds of low Voltage Pre-alert Timer. If the status of the VIP changed before this time-out timer
ends, the radio returns to normal operation.
If the status from the VIP unchanged when the time-out timer ends, the radio shows Low battery on
the display and also sounds low battery/voltage alert tone. The radio sounds a short, high-pitched tone
immediately after the PTT button is released.
NOTICE: If the mobile radio does not have a control head connected, the bricks can only alert
the user with battery alert tone and the transmit chirp.
