3. User instructions and maintenance
3.1 Precautions for normal use
l Be careful not to exceed the large signal range to avoid damage to the instrument receiving front end.
l When installing the antenna or RF cable, tighten the threads, but do not use excessive force to avoid slipping.
l Maintain sufficient power to avoid power-off;
l The USB interface is fragile. The plugging and unplugging should not be excessively forceful, and the lateral force should be avoided.
l Pay attention to the storage temperature and operating temperature range, such as not in the car.
l Long-distance transportation should be placed in a box or suitcase to avoid scratching the LCD screen with hard objects.
l It is recommended to use adapters to increase the life of the original interface.
l The RF connector is cleaned every 3 months and wiped with a cotton swab of absolute alcohol.
3.2 Application Environment Considerations
l Do not use the instrument when it enters water, shakes abnormally, or has other obvious abnormalities.
l Do not test outdoor equipment during thunderstorms, including outdoor equipment with lightning arresters.
l The normal warranty period is one year. If it falls, enters water and disassembles, it is not covered by the warranty.
l In winter, enter the heated room from the outside to avoid condensation inside the instrument. If the condensation should be dried, it should be turned on.
3.3 Battery Precautions
l Keep the instrument away from inflammable and explosive materials when starting or charging, pay attention to ventilation, and do not cover other items on the instrument and charger.
l In order to protect the battery, please charge the instrument frequently, and try not to charge it when waiting for the power shortage warning.
l Do not allow long-term floating charge. If the instrument is used for a long time, please do not charge continuously. Please use the battery intermittently to increase battery life.
