OPERATION GUIDE
3.2 Miscellaneous
1. Devise ways of isolating the MU-4 as far as possible from sources of noise, including from other embedded
equipment.
2. Arrange the MU-4 so that it will not be covered by the operator’s hand or the like.
3. The MU-4 does not have a waterproof structure. If the antenna is located outside the main unit, use a structure
that prevents water droplets from entering the case.
