5. BASIC OPERATION
5.1. POWER ON/OFF
To power ON, briefly press the red power button. Don’t keep your finger pressed,
otherwise the boot sequence cannot start.
It takes about 3 seconds to the receiver to be ready for operation.
To power OFF, press and hold the red power switch for 3 seconds. Don’t keep your
finger pressed passed the 3 seconds, otherwise the shut down sequence can’t
complete.
It takes about 3 seconds to the receiver to completely shut down.
During these 3 seconds, all receiver settings and frequency data are saved in the
receiver’s memory.
Note: Be sure not to suddenly interrupt power supply, otherwise the receiver will not
remember your previously saved receiver settings and frequency data.
