Warnings And Safety Notes - Eachine WT50 Operating Manual

3. Warnings and safety notes

• Never leave the charge unsupervised when it is connected to its power supply.
If any malfunction is observed immediately terminate the process and refer to the
operation manual.
• Keep away the unit from dust, damp, rain, heat direct sunshine and vibration. Do not
dorp it.
• The circuit of the unit is designed to be powered by a 10-18V DC only.
• This unit and the battery to charge or discharge should be set up on a head-
resistant, non-inflammable and non-conductive surface. Never place them on a car
seat, carpet or similar. Keep all the inflammable volatile materials well away from
operating area.
• Be sure to understand the information of the battery to be charged or discharged
accurately. If the program is set up incorrectly the battery can severely be damaged.
Especially Lithium battery can cause a fire or an explosion by over-charging.
• To avoid short-circuits between the charge lead, always connect the charge cable

to the unit first and only then to the battery to be charged or discharged. Reverse the
hsequence when disconnecting.
• Do not attempt to disassemble the battery pack arbitrarily.
