» Pull the throttle trigger completely to full throttle and use the “TH+” or “TH-“ buttons to adjust the throttle end point to 

the desired location.

Power Alarm:

•  Idle and Low-Battery Alarm

› When the steering wheel, throttle trigger, or any button is not operated for 10 minutes while the transmitter is on, a slow 

beeping alarm will sound to indicate that there has been no action and the power should be turned off and back on to reset 
the transmitter alarm.

•  Low Battery Voltage Alarm

› If the transmitter battery voltage drops to 4.5V or less, a slow beeping alarm sounds and the power LED light will blink.

Battery Replacement:

WARNING: Do not attempt to charge non-rechargeable batteries
NOTE: Load the four AA batteries in accordance with the polarity marking on the battery holder.

1.  Remove the battery cover from the transmitter
2.  Remove the old batteries

a. 

NOTE: Never mix brands or old/new batteries.

b.  Always be sure to be responsible and protect the environment when disposing batteries. Most local hobby dealers provide a 

FREE battery disposal service.

3.  Insert the four new AA batteries according to the polarity markings on the battery holder.

a.  If using rechargeable batteries, be sure to follow the manufacturer’s care and use instructions.
b.  Rechargeable batteries must be removed from transmitter before charging.

4.  Replace the battery cover.
5.  Slide the Power switch to the ON position.  If the voltage is low, the low battery alarm will sound.  If the low battery alarm 

sounds, check that the batteries are properly inserted and are making sufficient contact.

a. Low Battery Alarm.

i.  An alarm will sound if the transmitter voltage drops below 4.5V. This alarm is meant as a safety feature only. The trans-

mitter should not be operated below 4.5V. If the low battery alarm sounds, stop using your model immediately and turn 
off both the model’s receiver and the transmitter. Replace the transmitter batteries immediately with fresh AA batteries 
to prevent loss of control of your model.

b.  Always check the voltage of the transmitter before use.

6.  Always be sure to insert the batteries correctly according to the polarity markings, or the transmitter may be damaged.
7.  When the transmitter will not be used for 1 week or more, remove the batteries to prevent damage from leaks and corrosion.

Setting the ESC:

The ESC in your Criterion 10B is pre-programmed to work best with the HRS-3.1 radio system. Use with another radio system may 
not provide consistent performance and is not recommended for beginners. For detailed setup information refer to the Metric ESC 
setup section of this manual.

Standard operation:

•  When looking at the face of the transmitter wheel:

› Turning the top of the transmitter wheel to the left from center makes the wheels on the vehicle turn LEFT.

› Turning the top of the transmitter wheel to the right from center makes the wheels on the vehicle turn RIGHT.

» When driving your vehicle for the first time, take care and notice the direction the car turns when driving away from you 

vs. towards you. It is best to learn how things work when driving away from your position, 

but don’t go too far!

•  Pulling the transmitter trigger back towards the handle will make the vehicle accelerate forward.

› If instead the tires turn backwards you will need to disconnect and swap 2 wires going to your motor. Any two will do to 

reverse the motor direction.

•  Pushing the transmitter trigger forward away from the handle will have the following affects depending on the location of the 

trigger prior to pushing it forward.

› From a stop at neutral: the vehicle will travel in reverse.

› From pulled back: the vehicle will apply brakes to slow the speed.

» A second push forward of the trigger will apply brakes again

» A second push forward on the trigger will apply reverse throttle.

WARNING: Causing the vehicle to make quick transitions from forward/reverse motion to the opposite direction 
using the throttle control can cause damage to your vehicle and electronics and will void the warranty.
