Press the PULSE TIME selector switch once again to return to the default setting
(continuous blowing). No LEDs in the PULSE TIME section will be lit.
Once you have set the PULSE TIME setting, press the FAN ON, STANDBY selector
switch. The green LED next to STANDBY will blink three times, and then the fan
will turn on and run for the selected amount of time.
If you want a PULSE TIME to repeat itself, press-and-hold the PULSE TIME selec-
tor switch until the LED for the desired time interval begins to blink. Press the FAN
ON, STANDBY selector switch. The green LED next to STANDBY will blink three
times and the fan will turn on and run for the selected time interval and then turn off.
After a total of twelve seconds from when the fan first turns on, it will turn on again
and run for the selected time interval. For example, if 2 s is selected and you
press-and-hold the PULSE TIME selector switch (and then press FAN ON,
STANDBY), the fan will run for two seconds and then turn off for ten seconds before
turning on again for two seconds.
Charging the Fan Cart
The red LED next to CHARGING blinks when the battery needs to be charged.
Connect the AC to 9 V DC power adapter to an appropriate outlet. Plug the power
cord into the socket on the left side of the Fan Cart. IMPORTANT! Use only the
power adapter that is supplied with the Fan Cart to charge the battery.
The red LED next to CHARGING shines continuously while the battery is recharg-
ing. When the red LED stops shining, disconnect the AC power adapter.
The Fan Cart cannot be operated when the AC power adapter is connected.
