both intervals full on (the instrument
will not power down, and the scope
dot will never turn off). Care should
be taken in this mode, as it is highly
power consumptive.
5. Press Back twice to accept the new settings
and return to the main display.
Note:
If you have turned the beeper off, the scope
aiming dot turns off after every measurement, even
in ALL On mode.
If the instrument powers down while you are using
it, all measurements will be lost except for
cumulative distance.
Turning the Beeper On and Off
Although the Impulse gives helpful audio updates
that tell what the instrument is doing, you may want
to turn the beeper off and use the instrument
silently. This feature is available for instruments
with
red dot
scopes
only. To turn the beeper on or off:
1. Use Forward and Back as needed to display
the SYS indicator.
2. Press Fire to select the SYS option.
3. Press Forward repeatedly until UPDATE
flashes at the bottom of the screen.
4. Press Fire to toggle the beeper on or off. When
you turn if off, the flashes three times and
reads “OFF.” When you turn it on, the
instrument beeps three times and reads “On.”
5. Press Back twice to accept the new setting and
back out to the main display.
If the beeper is off, the scope aiming dot
automatically turns itself off after each
measurement. Press Fire to turn it back on to
prepare for a new measurement.
This setting will be saved upon power down.
