If you press PTT (Push-To-Talk) button, and you hear beep-beep, it is probably signal for LOW BATTERY LEVEL.You need to charge the battery before using it. If this does not help, either battery needs replacing or radio is faulty. Make sure both radios are on the same channel and sub-channel (Sub-audiable tone), otherwise you will not be able to communicate with the other radio user. More details will be in your Operation Manual, if you have mislaid it then you will be able to order another one from your supplier or HengLiDa themselves. Whether you’re hiking, bicycling, camping, or at an event, walkie-talkies (two-way radios) enable you to inexpensively stay in touch with friends and family. Unlike cell phones, two-way radios do not operate on a network, so you don’t have to worry about picking up a signal or experiencing dropped calls. Communicating is free with walkie-talkies-another advantage over cell phones. How do walkie-talkies work? They operate on radio channels. For two or more walkie-talkies to work together, they each need to be set to the same channel, although, you can’t talk at the same time as another person. To communicate with a walkie-talkie, you need to hold down a button while you’re speaking, and then let go when you want to hear the other person talk. Depending on the brand and model, walkie-talkies communicate at different distances. What communication distance do I need? For outdoor activities like bicycling, walking, rollerblading and skiing, a two to five-mile range is generally sufficient. For hiking, hunting or camping, you may want to choose walkie-talkies with a greater communication range for safety reasons. How are walkie-talkies powered? Most walkie-talkies either come with rechargeable batteries or use standard disposable batteries. Two-way radios with rechargeable batteries often take disposable batteries. This will come in handy if you forget to charge the batteries. Some models also include a battery-life indicator. Battery life varies by model and manufacturer. What are some other uses for walkie-talkies? As mentioned above, two-way radios come in handy for many outdoor activities and adventures. You can also use them in other situations like Business.
