Time out timer (TOT) function
TOT function can prevent long time transmit caused by the damage of overheating. When TOT is turned on,
automatically stop transmitting and enter receive status after transmitting for a period time.
TOT automatically stop transmitting, and a beep prompt tone.
Battery Save Function
In the standby state, the battery save function can greatly extend the use time. There are three battery save
model: 1:1, 1:2, 1:3.
Tone Tail Eliminate Function
At the end of the transmission, the end sound of the transmission is eliminated. When the receiver receives the
signal, it shuts down the receiving to eliminate the noise of the receiving tail.
Low Power Warning
When the power is low, red indication light every 30 second and "Low power" warning. When the power
continues to decrease, the two-way radio enters the low power state. When the battery power is very low, the
two-way radio will shut down automatically to protect the battery.
When the low power alarm occurs, please immediately charge, so as not to affect the normal use.
