In setup mode the NOSRAM MATRIX BRUSHLESS REVERSE stores every step when you press the SET button.
All the settings will be stored in the speed-controls memory even if the speed-control will be disconnected from the
battery.

TRANSMITTER SETTINGS
Setup the following basic functions on your transmitter (if available):
If your transmitter doesn‘t offer any of above functions, it‘s already in „basic setup“ mode.
• Ensure that the speed-control is not connected to the drive battery and is switched off.
• Remove motor pinion or ensure that the wheels of the model are free to rotate.
• Switch the transmitter on and set the transmitter throttle stick to neutral.
• Connect the speed-control to the battery, and switch the unit on.
• Hold the SET button pressed for at least 3sec using the supplied plastic screwdriver.
You entered setup mode and the SET LED flashes red (it will flash until the setup is completed).
• Leave transmitter in neutral position and press the SET button once.
Neutral setting is stored , MODE LED flashes green and the motor beeps.
• Hold full throttle on transmitter and press the SET button once.
Full-throttle setting is stored, MODE LED flashes red.
• Hold full reverse on transmitter and press the SET button once.
Reverse setting is stored, LED‘s glow red (MODE) and red (SET).
• This completes the setup procedure and your NOSRAM MATRIX BRUSHLESS REVERSE is ready to use.
• If you make a mistake during the setup procedure, don‘t worry: Disconnect the battery for about 10sec and
start again from the first step.
• At the end of each run switch of the car, and then switch off the transmitter.
• At the start of each run switch on the transmitter rst, then switch on the car.
• For storage of the car, disconnect the drive battery at any time!
FUNCTION STATUS MODE LED SET LED
Neutral (automatic brake inactive) -- off red
Neutral (automatic brake active) -- red off
Forward partial throttle green off
Forward full throttle green red
Brake/Reverse partial brake/reverse red off
Brake/Reverse full brake/reverse red red
CHECKING THE FUNCTIONS:
Check the LED‘s when moving your throttle stick and you will see if everything is setup correctly.
8. SPECIal FEaTURES
Internal-Temp-Check System: the NOSRAM MATRIX BRUSHLESS REVERSE allows you to read-
out the maximum internal temperature that the speedo reached. To save it to the memory you have to briefly
apply brakes after the run before you turn the switch off. You can convienently read-out the temperature back in
the pits since it remains stored until you turn it on the next time regularly (which will reset the memory). This
new feature allows you to accurately check if all is running well or if you‘re close to shutdown already.
How to read-out the temperature:
Switch at „OFF“ position.
Keep MODE button pressed while you turn switch to „ON“ (then release button)
SET LED will start to flash red (MODE LED is off), now count the number of flashes.
Basics:
• Thermal shutdown of the speedo would occur at 6 ashes.
• The higher the number of ashes, the cooler the speedo ran (e.g. the better it is!)
• Every ash equals to ~8°C temperature decrease
Example:
you count 10 ashes after the run
10 - 6 = 4 (e.g. 4 ashes „away“ from shutdown)
4 x 8°C = 32°C (e.g. you are 32°C away from thermal shutdown and therefore safe!)
SmartCell System: Ready for the next battery technology – LiPo batteries! NOSRAM’s exclusive and
smart SmartCell System ensures that LiPo batteries can be used safely without accidentially deep-discharging
of the cells. The motor function will be shut-off and the SET LED will flash if the system recognises very low
battery voltage.
Tip: We recommend using value 2 for 4-6 cells NiMH racing purposes, which disengages the LiPo protection.
Automatic Brushless / Brushed Adaption: The NOSRAM exclusive Automatic Brushless/
Brushed Adaptation detects the connected motor type during turn-on/initialisation and adjusts the correct
brushless or brushed operation automatically. No adjustments required by yourself, apart from the correct
connection of each motor type (don‘t forget the hall-sensor-wire for brushless!).
Caution: Keep in mind, when swopping between brushless and brushed motors, that the chosen mode values
will be identical!
Changing Mode settings without the transmitter: At race events you usually do not
have access to your transmitter, but never mind since you can simply disconnect the receiver lead from the
receiver and change the MODE settings as described in section 7 „Mode Programming“.
FreezeDrive Design: NOSRAM’s secret FreezeDrive Design results in lower speedo temperature under
all racing conditions and for both brushless + brushed. Sorry, no further details to be disclosed. Simply a step
ahead of the competition!
Works-Default-Settings: All NOSRAM speed-controls come factory-adjusted (defaults are grey-
shaded above). If you loose track of the modes, you can restore the works default settings. With the transmitter
switched on, hold the SET button pressed while you switch on the speed-control. This simple action returns the
unit to the NOSRAM works default settings.
Power Capacitor: Never disconnect the power-capacitor! It is required for proper function, a special
SuperLow ESR type has been choosen, which offers increased punch and additional protection, therefore only
use genuine NOSRAM power capacitors.
Sensored Brushless Technology: Enhanced Digital allows the perfect knowledge of the brushless
motor’s magnet position. This results in perfect motor control at high and low RPM‘s, as well as perfect
brake control.
3-Way Protection System: The perfect protection against short-circuits (motor), overload and
overheating. If your speed-control faces overload, the motor function will be shut-off for protection and the SET
LED will flash, although the steering function is maintained. Let the speed-control cool down for a few minutes.
If you experience frequent shutdowns, check for the following:
• Correct gear ratio (refer to motor manual for gearing recommendations)
• Power prole setting too high (higher value will heat up motor and speed-control excessively)
• Motor is too strong or motor is damaged.
All modes are available for brushless and brushed motors (speedo adapts automatically). The NOSRAM MATRIX
BRUSHLESS REVERSE features 4 modes which enable you to adjust it to YOUR special requirements. The
factory settings are shown in grey colour.

• How to get into „programming the modes“ Press MODE button for 3 or more seconds.
• How to check the stored values
Count the number of flashes of the red SET-LED
(1x = value 1, 2x = value 2, etc.).
• How to change the value
Press SET button to increase value by one step.
• How to get to the next Mode
Press MODE button once.
• How to leave the programming mode
If you are in MODE.4, press the MODE button
one more time
• Table of settings, values and modes: see below (grey-shaded values show „works default settings“)
MODE.4 - Auto-/Dragbrake
allows you to set a slight braking action which is applied in the neutral range. This enables you to simulate the
feel of a brushed motor and also hold the throttle on longer when entering a turn. Your car also has more front
traction with this setting.
For brushless motors you achieve the same natural slowdown as a brushed motor with no autobrake when you
set value 1-2 (for motors with bonded magnets) or 0-1 (for motors with sintered magnets).
