High performance 3 CHANNEL Computer R/C INSTRUCTION MANUAL D I S P L AY L
Safety Precautions Thank you for purchasing this CIRRUS 3CFM computer radio control system. Before using this radio, and to ensure your safety and that of others, it is important that you read this manual thoroughly, and understand it, prior to installation and operation. After reading this manual thoroughly, store it in a safe place so that you can easily find it again should the need arise. Just as commercial radio stations have their own frequency bands, so do radio control systems.
Nomenclature / Handling 1 4 Transmitter: 3CFM 5 2 8 9 1. Antenna 2. Power Switch: Turns your transmitter ON & OFF. 3. Charging Jack: For onboard charging when using rechargeable batteries (not supplied). See page 5 For details. 4. Strap Base: For the securing of an optional safety strap (not supplied). SEL 5. LCD Display: Displays all menu screens for function updates, power level indicator, etc.
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.
Charging (For Rechargeable Batteries) Caution! Never try to charge dry cell batteries in the transmitter. They will leak and could explode. To prevent the possibility of accident, overheating and/or short circuit, always disconnect your battery charger from its power supply when not in use.
Throttle Trim Function The throttle trim allows you to fine-tune the position of the throttle servo or speed controller so as to give correct throttle response. When you first switch ‘ON’ your transmitter and model (and start the engine in the case of an engine powered model), the drive wheels on the model should not be turning. This is the neutral position. If the drive wheels are turning (either forwards or reverse), you can adjust the throttle trim to stop them and bring your model back to neutral.
Dual Rates Dual Rate function allows you to vary the amount the servo moves (or speed controller responds) in response to transmitter inputs and reduces/increases the movement/response evenly, left and right of centre/neutral. As a result, you can set your model up to have very little response, a lot of response, or somewhere in between. This can be easily adjusted to your own preference depending on the type of surface you are running the model on and the handling characteristics you want.
EPA Setting on CH1 (Steering to the Left) Press the button five times in normal display mode to enter the EPA setting menu for Channel 1, steering to the left. Push the ‘DT1’ button to the left to decrease servo movement to left of centre and to the right to increase servo movement to left of centre. The changing range is from 120% down to 5%, moving in 1% increments.
EPA Setting on CH2 (Brake/Reverse), with ‘DT4’ Button This function allows the quick change of reverse/braking EPA without having to access the on screen menu using the button and then scroll through the various screens, and is useful for making quick function changes when at the track or similar. The button works the same as ‘DT1’ above, with the same range of change and increments of change. Also, changes made using the ‘DT4’ button will show on the LCD display.
Anti-Lock Braking System (ABS) Setting on CH2 (Throttle & Reverse/Brake) Slowing or stopping a car in slippery or loose conditions can be quite challenging. Simply locking the wheels, as in conventional braking, will cause a loss of traction and steering control, resulting in an out-of-control slide. ABS allows you to slow down faster whilst still being able to steer effectively by ‘pulsing’ the brake function so that the wheels do not actually lock up.
(Range Check Procedure - Engine Powered Car) Install fully charged batteries (either dry or rechargeable) in the model. Switch on the transmitter, then the receiver. Follow the engine starting procedure. Ideally, have a friend hold the model or place it on a stand where the drive wheels cannot come into contact with the ground. Leaving the transmitter’s aerial fully retracted, move approximately 10m (30 feet) from the model.
• • Near steam and/or condensation Where the system could be exposed to engine exhaust Note: Storing your Cirrus R/C system under the conditions outlined above can result in deteriation/ deformation of the casing and damage to the electronics. Receiver, Servo and Speed Controller Connection Note: Use base illustrations as created for the 2CAM instructions, although these will need to be modified slightly to show 3rd channel servo. Connections for installation in an electric powered model.
Technical Information The CIRRUS 3CFM computer radio control system is supplied with differing servos, depending on its application. You should check your own model to ensure which type(s) is/are installed. A list of specifications for the most common types is given below. Transmitter 3CFM (3 Channel, FM type) Transmitting Frequency: 27/40MHz Modulation Method: FM Power Requirement: 12V (8 x AA) Receiver 3CFM RX (3 Channel, FM type) Receiving Frequency: 27/40MHz Power Requirement: 4.
Troubleshooting PROBLEM CAUSE REMEDY Model will not move/ No batteries in transmitter/model does not recieve a signal Battery installation is incorrect Install batteries correctly, noting + & - symbols Replace/recharge batteries Weak batteries in transmitter Install batteries Weak batteries in model Replace/recharge batteries
Warranty Information In North America Your Cirrus 3CFM computer radio system is warranted against manufacturer defects in materials and workmanship for a period of 90 days from the date of purchase. Warranty service will be provided within 90 days of the date of purchase only if you are able to provide the original or a copy of the original dated sales receipt.
