Location
PU901 should be positioned so that the user can easily blow straight into the propeller.
The push contact can be mounted on e.g. a gooseneck, contact your retailer for more information.
Service
When the user blows hard enough on the propeller to activate PU901, it will flash a green light.
The receiver will give an acknowledgement, after which PU901 will glow steady green, indicating
that the transmission was successful.
If the transmission fails, PU901 repeats the transmission up to 2 times at 30 second intervals.
Battery alarm
If the battery in PU901 is low, the receiver will display "Low battery" when an alarm is received
from PU901.
Changing the battery
The top and bottom of the PU901 can be unscrewed without tools.
The battery is gently pressed out of the holder,
for example with a cotton swab or a match.
Never use a metal object.
Carefully insert the new battery into the holder
WITHOUT
using tools, as this may short-circuit the battery.
Use a CR2477 battery.
IMP must be facing up.
After replacing the battery, check PU901 as described under "Testing and commissioning".
It takes about 1 minute after battery replacement before it can be activated.
