7. Channel memory
Adopt frequency synthesize technique,can memory 16 frequency synthesize and semiduplex channels.

8. LED two colors LED
Two colors LED,indicate transmitting /receiving status.

9. 5W HF output power
Adopt the new model of FET power enlarger,and insure the transmission power to output steadily

10. Built-in CTCSS/DQT
Built-in 38 groups selective CTCSS/DQT,prevent interference among the same
Frequency and enable transferring and selective Group Calling

11. Time-out timer
Time-out-timer function can stop the transmitting automatically to avoid any damage caused by long-time continuous transmission.

12. Battery save
No signal receiving,can come into stand-by status,decrease the consume electricity of incept electric circuit working,then extend the use time.

13. Low battery warning
While transmitting,if the battery power goes below a pre-determined value,the red LED will blink and send out a tome sound,indicate that should replace or recharge the battery.
