Notes
1. 3 MHz analog function generator should be equipped with suitable line voltage.
2. To avoid electrical shock, the protective grounding conductor of power cord should be connected to ground.
Maintenance
1. To maintain good ventilation, regular cleaning should be carried out.
2. Do not spray cleaner directly onto the instrument when cleaning it. Please use a soft cloth with mild detergent and water instead.
