Users must also be familiar with the

aware that removing the microphone triggers
mode change most of the time.

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.
Note:
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.
