The beeper sound is the same volume as the speaker sound.
The beeper sounds even if the sperker sound is turned off.
If the beeper does not sound, turn the main power switch on and off repeatedly and
do the transmission procedure 2 or 3 times.
If the beeper does not sound after turning the main switch on and off 3 times, you
need to input the settings stored in SRAM memory manually.
