13. Specifications
A.
Communication sensitivity improves the most when a speaker and a receiver are located in
face-to-face. On the contrary, the sensitivity declines drastically when a speaker and a receiver
face opposite with each other. Check your facing directions.
B.
Check whether a bone-conduction microphone is touched on the right position on the
speaker's face as stated in the [4. How to set the unit].
C.
Transmitting and receiving quality gets degraded drastically when hood, cover, or air bubble
are attached to antennas. Please check.
D.
Low voice may not reach a receiver. Talk with large voice as same as talking to a person away
from you on lands.
E.
Ultrasonic wave may not reach a receiver correctly behind rock, in the shallow water, and in
rushing stream, but itʼ s not malfunction.
