If the repeater is busy, wait until it is clear, or ask for a "break" using a method acceptable to your local procedures. • The transceiver has a Time-Out Timer function for digital repeater operation. The timer limits a continuous trans- mission to approximately 10 minutes. Warning beeps will sound approximately 30 seconds before time-out and then again immediately before time-out. 7-7
