Audible alarm
1. When the transmitter battery is low and the voltage is lower than 3.75 V, the system will make alarm which sounds slowly.
2. If the voltage is lower than setting data due to low battery of receiver, the system will make a sound "Ba,Ba".
3. When the error rate is more than 60%, the system will make a sound "Du,Du".
4. When the timer goes off, the system will make a sound ''Bi, Bi, Bi, Bi'" three times.
5. Before the transmitter is turned off automatically , the system will make a sound "Du Du Du".
6. When the transmitter's battery voltage is lower than 3.7 V, the system will make alarm which sounds quickly.
When the voltage is lower than 3.65 V, the transmitter will be turned off automatically.
LED indicator alarm:
LED indicator alarm function synchronizes with audible alarm function. It has no effect on LED indicator after
turning
off the audible alarm. Please check as follows:
1.The LED remains on: all functions are normal.
2.The LED flashes slowly: the transmitter battery is low.
3.The LED flashes quickly:
The battery of the transmitter is very low,
Error rate is more than 60%,
The battery of receive is low,
The transmitter will turn itself off soon.
4.LED indicator is off: power off.
