BATTERY REPLACEMENT
If the meter will not power up as usual or
the display contrast becomes weak and
difficult to read, replace the lithium
battery. To do so, turn the battery
compartment cover in a CLOCKWISE
direction to remove it. (See Fig.13)
The battery will be visible in the battery
compartment, observe the position of
the battery and replace the new one in
the same position. Affix the battery
compartment cover by turning it in a
COUNTER-CLOCKWISE direction.
Dispose of the lithium battery in accor-
dance with local, state, or national waste
disposal codes.

VANE REPLACEMENT
The anemometer is very accurate at low
and mid-range air speeds. Constant use
at very high speeds, such as measure-
ments out a fast-moving car window, may
damage the impeller's bearing and reduce
over-all accuracy.
To replace the impeller, use a small
screwdriver to loosen the set-screw found
on the back of the windmeter.

The meter will automatically shuts down
to preserve battery life after 15 minutes
of inactivity.
AUTO POWER OFF

The remove the impeller by twisting the
impeller assembly clockwise (if you are
facing the back of the windmeter) to the
"O" position marked on the rear of the
rear of the meter. (See Fig.14)
Install a new impeller by following above
instructions in reverse.
