4. പരിപാലനം
Your Two Way Radio is an electronic product of exact design and should be treated with care. The following suggestions will help you maintain your radio:
- Do not attempt to open the radio for any reason. Unauthorized opening voids the warranty.
- Do not store the radio under direct sunlight or in hot areas. High temperatures can shorten the life of electronic devices and warp plastics.
- പൊടി നിറഞ്ഞതും വൃത്തികെട്ടതുമായ സ്ഥലങ്ങളിൽ റേഡിയോ സൂക്ഷിക്കരുത്.
- റേഡിയോ ഉണക്കി സൂക്ഷിക്കുക. മഴവെള്ളം അല്ലെങ്കിൽ ഡിampഇലക്ട്രോണിക് സർക്യൂട്ടുകളെ നശിപ്പിക്കും.
- If the radio emits a peculiar smell or smoke, immediately shut off its power and remove the charger or battery.
- ആന്റിന ഇല്ലാതെ പ്രക്ഷേപണം ചെയ്യരുത്.

- ഹെഡ്ഫോണുകൾ: If your package did not include headphones and you require them, please check the product listing for specific bundle options or consider purchasing compatible Kenwood 2-pin accessories separately.
- പാക്കേജ് ഉള്ളടക്കം: The standard package typically includes one walkie-talkie. If you require multiple units, ensure you select a bundle or quantity that specifies more than one radio during purchase.
- പരമാവധി പരിധി: For the maximum advertised range (5-10km), ensure the radio is set to high power output. Environmental factors such as terrain, obstacles (buildings, dense foliage), and atmospheric conditions significantly affect actual range. Operating in open, elevated areas will yield the best results.
