Attention
For infrared communication, be sure to communicate with one dosimeter at a
time. Do not communicate with more than one dosimeter at a time, such as
arranging multiple dosimeters.
Also, do not communicate near objects that reflect infrared rays, such as
mirrors.
Otherwise, data may be written to other dosimeters by mistake, a data error
may occur, or communication may become impossible.
