● Plug the Receiver into any socket of AC110~240V power.
Import note:
Please test the operating rang between the Receiver and Transmitter. The operating range is 150M
(in the open air) , but this distance may be less due to walls or obstructions such as Metal or UVPC
door frames can also reduce the operating range.
Functions Instruction
1. Plug the Receiver into any socket of AC 110~240V power，then open the transmitter and
place the battery as shown in the diagram.
2. Press the auto-learning code button on the side of the Receiver and hold for 2 or 3 seconds, A
“beep” sound comes out and the LED indication will light.Then press the push button on the
Transmitter unit once. The Receiver will sound to indicate that new operation code is registered
and memorized. Thus the Transmitter works successfully with the Receiver. Maximum 60 codes
can be matched and saved in the receiver within 10 seconds.Press the button once can only
match one transmitter. If there is no code matched and saved within the 10s, the receiver will
automatically exit and there will be two “beeps”.
3. If you want to add Receivers, you just need to plug the Receiver into any socket of AC 110~240V
power. Then operate in the same way as step 2.
4. There is a melody selector located on the side of the Receiver (see diagram).
Selectable Tone: Total 36 melodies available.
Note: You must select the desired ring first, then match the transmitter. You could use different
music to distinguish visitors in different position. If you want to change ring tones, you must
delete all the information saved in the receiver and reset.
Press the melody selector button and hold for 5 seconds, you can delete all the information
within the receiver. At the same time, the LED indicator light will light.
5. There is also a volume button on the side of the Receiver (see diagram). Press it to adjust the
sound volume, total six levels.
6. There is a Sound and Flash Switch Button on the side of the receiver. Press this button for three
options, working only with sound, only LED flash, sound and LED flash:
A. If a “beep” sound comes out and the LED indicator does not light. the Receiver will work only
with sound.
B. If a “beep” sound comes out and the LED indicator light, the Receiver will work with sound and
LED flash.
C. If the LED indicator light without “beep” sound, the Receiver will work only with LED flash.
