Because of the capacity consumption during the storage and transport course, the battery
capacity is not full when it is used for the first time. Battery recharge should be considered
before the first use.
NOTE: If the battery has not been used for more than two months, it should be
recharged before use.
3) Replacement
When the useful life of the battery is over, or foul smell and leakage are found, please
contact the manufacturer or the local distributor for replacement.
12.4.2 Recorder Paper
NOTE: Recorder paper provided by the manufacturer should be used. Other paper
may shorten the life of the thermal print head. And the deteriorated print head
may lead to illegible ECG reports and block the advance of paper.
Storage Requirements:
♦ Recorder paper should be stored in a dry, dark and cool area, avoiding excessive
temperature, humidity and sunshine.
♦ Do not put the recorder paper under fluorescence for a long time.
♦ Make sure that there is no polyvinyl chloride or other chemicals in the storage
environment, which will lead to color change of the paper.
♦ Do not overlap the recorded paper for a long time, or else the ECG reports may
trans-print each other.
