4.Safety

Read the Safety carefully before you use the device.
- Please read instructions carefully and follow them before you start the measurement.
- UT336E is incompatible with refrigerants containing ammonia and must not be used together with ammonia refrigerants.
- Check the device and accessories before you use the device. Replace a new refrigerant hose when it gets broken by dropping or other damages. If the high/low-pressure valves are damaged, or the housing of device is damaged or no screen display occurs, do not continue to use the device.
- Do not disassemble or change the internal wires of device randomly.
- When the low battery icon shows on the screen, charge the battery to ensure its normal use and accurate measurement.
- Please charge the device using a standard DC 5V adapter. Do not use power supplies or adapters with other voltages, may cause damage.
- Do not store or use the device in high-temperature, high-humidity, flammable, explosive, or strong electromagnetic environments.
- Use soft cloth and neutral detergent to clean the housing of device. Do not use abrasives and solvents to avoid housing corrosion and device damage.
