Main Unit
Make sure the instrument is powered off.
Clean the instrument and accessories. Put on the dustproof cover after use.
Place the instrument in a dry and cool environment. Prevent from shaking violently when moving it
to another place.

）
Check the animal cable is well-collected according to the following table. The resistor between
the electrode plug and plug pin of the animal cable plug should be less than 10Ω;
Note: the resistance or of animal cable with the function of defibrillating protection is around
10KΩ.
