Notes for usage

a. Pls use soft lead wire or other hard metal (like telescopic antenna), It can not be either too long or too short, or it will affect the receiving distance. The antenna should be stretched as straight as possible if it is using soft lead wire, and as far as possible from the metal objects.

b. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)

c. We suggest the clock frequency of the MCU should be lower than 4MHZ if used together with MCU, the crystal should be as far as possible to the RF receiving module, or the higher harmonic of the crystal will affect the communication distance.

d. There is short distance signal block up problem during the work of the ASK receiver module, pls pay attention to it during the operation. 

Garantee: 13 months !

Lead time: 

   1. Samples: 3-5 working days after receive the payment;

Shipment: 

 We deliver by EMS, DHL, UPS, TNT, FedEx, Hongkong Post, Singapore Post and so on at the first reasonable time.

*EMS usually takes about 6-13 days, more or less. For far region or custom reason, it will take a little longer time, pls be patient;

*DHL, UPS, TNE, FedEx usually takes about 4-6 days, For far region or custom reason, it will take a little longer time, pls be patient;

*Hong kong post, Singapore post usually takes about 10-15 days, For far region or custom reason, it will take a little longer time, pls be patient;

*We usually show very low price, so the buyer can avoid paying the tax. However, the tax is determined by the custom of the destination, not by us, different countries have different tax rate, so if any tax, then the buyer should undertake it. If you have any special requrement, pls let us know before the order.

*We will not responsible for any loss due to the buyer's reason, including"refuse to sign the package" or "refuse to pay the tax" or "destination country post reason". We are in charge of delivering the goods in good condition, once the express carrier sign the airway bill, we will not be in charge of any responsibility.
