4.2.2 Sounding Rate
The sounding rate is set with S2 (#1) DIP switch on the CONT-B 01P5741 board. The
switch is factory-set to "HIGH" (190 times/min).
When "LOW" is selected, the rate is down to 1/3 approximately. See table below.
The relation between sounding rates and Upward/Downward ranges is shown below.

4.2.3 Signal Transmitting Power
The signal transmitting power can be changed from 2.4W to 10 W or vice versa by
changing the jumper connections (Jxx1 and Jxx2) on the CONT-A Board (01P5740).
Note: Increasing output power decreases the battery operating hour by 50%
approximately.
The factory setting of the Output Power is 2.4 W
