signal is received for 5 seconds.
• When the temperature is extremely high, the battery protection function automatically
sets transceiver power to Low, and disables High power selection.
• The Time-out Timer function* cuts OFF transmission after 5 minutes of continuously
transmitting, to prevent prolonged transmission. 10 seconds before transmission is cut
off, a beep sounds to indicate the transmission will be cut off, and "tot" blinks. After it is
