Should be charged before use, with the special charger or self-charging plug line to charge, charging current can not be too large; Charger polarity can not be reversed; The electric shock function shall not be used during the charging process and within five minutes after charging, otherwise the product life will be affected; The charging time is about 6-8 hours, otherwise it will shorten the battery life, and even cause the battery to burst and damage the battery. Storage for one month, should be checked and charged, more than one month of long-term storage, should be placed in a dry, well-ventilated room, should be charged once a month. Charging should be used after 5 minutes of lighting or use an electric shock after lighting, otherwise easy to damage the bulb.

First adjust the DC-AC converter so that the B1 secondary voltage is above 200V, and should not be lower than 160V when connected to 39k load. After the whole machine is connected, the ZD shines, and the high-voltage pulse transformer makes a \"snap, snap\" sound. Connect the voltmeter 咵 between the thyristor positive and cathode, and the maximum oscillation of the meter should be close to 150V. The oscillation period of the multivibrator should be synchronized with the C2 charging period, that is, the arrival of the multivibrator pulse when C2 is fully charged should trigger the thyristor. This can be done by repeatedly adjusting the values of R2, C2, C3 to take into account each other, in order to synchronize as much as possible, in order to obtain the best output. After the adjustment, the high voltage pulse frequency is between 60 and 110 times per type.
