Chapter 2 Unpacking
1. Model confirmation
When you open the package, you will see the following items:
1x Main Machine
1x Power Cord
1x U Disk (for documents)
Please check carefully for any incorrect or missing items against the order contract and the packing list. If
there is any problem, please contact our operation center according to the contact information in the
preface, and we will solve it as soon as possible.
2. Visual examination
Check the instrument carefully for any damage during transportation. It is strictly prohibited to switch on
the instrument if any obvious damage to the instrument is found. Please contact our operation center
according to the contact information in the preface. We will repair or replace the product accordingly as
soon as possible.
3. Operating environment
Please refer to the environmental adaptability part in Technical Indicators section of this manual. And
please pay special attention to the following requirements:
Power supply: 220V (±10%), 50Hz (±5%)
Power socket:
3-core power socket must be used, and grounding is strictly required.
Power cable of the instrument:
3-core power cable provided in the package
For the safety of users, anti-static accessories must be provided with at least 1M
Ω
isolation resistance
from ground.
Before connecting the solid-state power amplifier to the power supply, please check carefully whether the
supply voltage is normal and whether the connector at the output end of the amplifier is connected with a
high-power load, otherwise it is very likely to cause damage to the instrument!
4. Electrostatic protection
Static electricity is extremely destructive to electronic components and instruments. The required
anti-static measures must be completed on an anti-static workbench. Usually we take two anti-static
measures: conductive table mat and wrist strap, conductive floor mat and ankle strap. For the safety of
users, anti-static accessories must be provided with at least 1M
Ω
isolation resistance from ground.
