The IC-M412 uses a technology to clear water away from 
the speaker grill: AquaQuake. AquaQuake helps drain water 
away from the speaker housing (water that might otherwise 
muffle the sound coming from the speaker). The IC-M412 
emits a vibrating noise when this function is being used.

➥

 While holding down both 

[Y] and [Z] on the transceiver, 

turn ON the power to activate the AquaQuake function.

 • While continuing to push

[Y] and [Z], a low beep tone sounds 

to drain water, regardless of the 

[VOL] control setting.

 • While the AquaQuake function is activated, the transceiver

never accepts any key operations.

 • Release

[Y] and [Z] to cancel the AquaQuake function.
