##### Lock/Unlock Keys
The TXM control has a lock to prevent the control keys from being accidently
pushed. Follow these steps to lock and unlock the keys of your control:
1. Press the POWER button. The control’s transmission LED will remain on.
2. Press the SOURCE **SRC** and MUTE keys at the same time. The transmission LED on the control will blink 2 times indicating that the control is locked or it will blink 5 times indicating that the control has been unlocked.
**Synchronization of the STM 1003**
The STM 1003 and its TXM control are SYNCHRONIZED at the factory. If the owner
purchases new TXM controls to use with the STM 1003, whether to replace the
current control or to have more than one control, follow these steps:
**Note:** Before beginning the synchronization, make sure there are no other
TXM controls operating within the range of the STM 1003 as they could
interfere.
1. Press the SYNC/RST key on the rear panel of the STM 1003. The sound mixer’s LED will blink for 15 seconds.
2. Press one of the TXM control’s keys (except the POWER key)
3. The LED of the STM 1003 wil stop blinking. Sync is complete.
To synchronize more than one control (maximum 8), repeat steps 1 to 3. If more
than 8 controls are synchronized, the newest control will override the oldest
control.
**Undo the Synchronization of a Single Control**
1. Press the SYNC/RST key on the rear panel of the STM 1003. The mixer’s LED will blink for 15 seconds.
2. Press and hold the POWER key on the TXM control that you want to remove.
3. The LED of the STM 1003 wil sto blinking. The control has been successfully removed.
**Undo the Synchronization of All Controls**
* Press the SYNC/RST key on the back panel of the STM 1003 for 5 seconds.
* All the controls have been successfully removed.
##### Low Battery Indicator
When the battery is low, the transmission LED on the control and the LED on
the back panel of the STM 1003 will remain on for 1 second after you release a
key on the TXM control. We recommend that you replace the battery with a new
battery model CR2032, since the control could stop transmitting efficiently.
The TXM transmitter has a system that automatically shuts off any key that is
pressed for more than 10 seconds to avoid unnecessary battery consumption.
When you release the key, the system operates normally again.
**Replacing the TXM Control Battery**
Remove the Holster, open the back of the control, remove the electronic board
from its plastic housing and replace the discharged battery with a new one.
Pay attention to the indicated polarity, the Clip must be in contact with the
POSITIVE terminal of the battery.
**Loss of Synchronism**
Loss of synchronization occurs when the TXM control’s keys are pressed more
than 250 times while it is out of range of the STM 1003. When this happens,
the STM 1003 stops responding to the TXM control’s commands and its indicator
LED blinks permanently. Re-synchronize the control with the STM 1003 to
restore operation.
#### Installation Example
**Compatible Cables**
#### Troubleshooting
**DOES NOT TURN ON OR LED DOES NOT LIGHT UP:**
* The power cables are not properly connected (terminals 12V, GND and REM).
* The power cables have a poor connection. Check the connections.
* REM without current. Check to see if the REM connection is receiving about +12V of current.
* Poor ground connection. Check the connections.
**REMOTE CONTROL NOT SYNCHRONIZED WITH THE STM 1003:**
* Follow the steps for “Synchronizing with the STM 1003”;
* Low battery in the control. Follow the steps for “Replacing the TXM Control Battery”
**NO AUDIO SIGNAL:**
* LEVEL controls of the channels or MAIN are at the lowest setting. Increase the setting.
* MUTE button of the channel is pressed. Unmute it by pressing the button again.
* The signal cables to the channels or Main are disconnected. Check the connections.
**DISTORTED AUDIO SIGNAL:**
* Distorted/saturated audio signal. Adjust the volume level of the signal source. Decrease the gain control of the STM 1003’s input channels.
**UNDESIRABLE NOISES:**
* All RCA and power cables must be checked for irregularities beforehand and corrected if necessary.
* Use suppression wires on the spark plugs.
* Route the incoming and outgoing RCA cables away from any other cables since they are more sensitive to interference.
* Install a separate power source (+12V) for the sound system.
* Ground the STM 1003 properly. To do this, remove the paint from the vehicle’s chassis at the selected point and connect the wire to a grounding terminal. In order to prevent rust, insulate it with paint.
* Place the STM 1003’s ground wire as close as possible to the ground wires of the other audio equipment that it is used with.
* Do not loop the ground wire. Avoid using multiple grounds. If possible, use a star connection where all the grounds run from a single point.
* If you use a 12V power source for the STM 1003 that is separate from the rest of the system, connect the ground (-) wires of all the sources together.
