Battery Installation / Replacement Method
1. Remove the battery cover from the base of the transmitter by sliding it in the direction of the arrow embossed on
the cover itself.
2. Insert 8 x AA/UM3 batteries (fresh dry cell or fully charged rechargeable recommended), ensuring the batteries
are fitted the right way round, observing the + and - signs on each battery.
3. Slide the battery cover back into place until it is fully seated.
Note 1: Do not mix old and new batteries. Do not mix dry cell and rechargeable batteries.
Note 2: If you do not intend using your model for an extended period, we recommend that you remove all
batteries from the radio and the model and store them safely until needed again.
Note 3. If batteries do leak, clean battery case and contacts thoroughly - plastic parts can be wiped clean with
a damp (not wet) cloth with mild detergent and metal contacts with an alcohol based liquid, being careful to
avoid getting battery residue on your skin. Always perform any clean up of this kind in a well ventilated area,
taking care to observe all warning labels on the cleaning products themselves.
Check
Turn the power switch on your transmitter to the ‘ON’ position. The LED indicator will glow red and you will hear 3 audible
beeps. At the same time, the LCD screen will illuminate. If the LED fails to light, no beeps are heard and the LCD display
fails to illuminate, double check that you have installed the batteries the correct way round in the transmitter and try
again. If the LED still fails to light and no audible beeps are heard, check that the batteries you have installed are fully
charged.
Note: The Cirrus 3CFM transmitter is not reverse polarity protected. Always ensure that you put the batteries
in the correct way round or damage to the transmitter will result. For ease of identification, there are raised
images of each battery in the battery tray to indicate correct orientation.
Battery Power Display
When the red LED is lit, and the LCD display shows battery power of
12v ~ 8v, there is sufficient power for use.
When transmitter voltage drops below 8v, the LED indicator will start to flash
and an audible beep will be emitted every 2 seconds. At the same time a
low battery warning symbol will appear in the lower right hand portion of the
LCD display. At this time you should immediately stop using the radio and
replace/recharge the batteries or control will be lost.
