Warning

Deposite Oscilloscope

Please do not store or put the instrument on the

place where the monitor would be exposed to

sunshine for a long time Be careful

keep the

instrument or probe away from the sprays

fluids and solvents to guard against damage to

the instrument or probe

.

:

,

.

Check the instrument and probe usually in

accordance with the operation status and clean the

instrument surface under the following steps:

1. Please wipe dust on the instrument and probe

with the soft cloth and do not scrap the transparent

LCD protection screen.

2. Please power off when clean the instrument with

the wet cloth without dripping. The soft detergent or

clean water could be used to clean the instrument

instead of any corrosive chemical detergent which

might damage the instrument or probe.

Before using the apparatus after being

powered on again, please confirm that it has been

dry, guarding against the electric short circuit

caused by water and even the personal hurt.

It is required to recharge lithium ion battery before

deposit the oscilloscope if want to deposite it for a

long time.

In delivery, lithium ion battery may not be

recharged enough. To maintain enough battery

electricity, recharge it 4 hours, after that, the

battery shall supply power at least 8 hours.
