SmartMute
™
SmartMute
™
is a unique new feature of
the ESD-9860 that allows you to avoid
alerts you don’t need to hear because
you are stopped or moving slowly. By
sensing the “revs” (RPMs) of your
engine, SmartMute
™
knows when you
are at low speed and automatically
mutes all alerts (except for strobe
signals from emergency vehicles).
Before SmartMute
™
will work, you must
set an activation point for your engine’s
revs (see page 10). Whenever the revs
are below that point, SmartMute
™
will
begin muting. The activation point will
be stored in memory and recalled each
time power is turned on.
When you turn SmartMute™ on while
in Voice Alert™ mode, you will hear
“SmartMute on.” In Tone mode you
will hear two beeps. “s” will appear in
the display. When you turn SmartMute™
off while in Voice Alert™ mode, you will
hear “SmartMute off.” In Tone mode you
will hear one beep. (See page 7 for
instructions using the Program mode to
select SmartMute
™
.)
The factory setting is SmartMute
™
off.
NOTE: SmartMute
™
may not work with
some vehicles because it cannot sense
the engine’s revs. In such cases, you can
reduce unwanted audio alerts by using Auto
Mute and City modes when appropriate.

What to Remember
While Using SmartMute
™
SmartMute
™
works with both City and Auto
Mute modes.
Whenever engine revs are below the
activation point, an arrow pointing down
will appear in the display.
Above the activation point, an arrow
pointing up will appear.
If, for any reason, the unit stops sensing
your engine’s revs, SmartMute
™
will indicate
an error and automatically turn off.
The rev point you set will be stored in
the unit’s memory when power is turned
off, and recalled each time the power is
turned on.
The rev point must be reset if you use your
ESD-9860 in a different vehicle.
Important: When initially choosing your
SmartMute
™
activation point, a setting of
approximately 300 to 600 RPMs above
idle is recommended. You can reset the
activation point at any time to fit your
individual preferences and driving style.
