AquaQuake water draining
function
The transceiver 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 transceiver
makes 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.
