Up to 15 Transmitter units can be learnt by one Rx unit. (The article says 16 but the technical

manual says 15.) Press button 1 (the button all by itself) while simultaneously pressing the LEARN

tact switch on the main board. You only have to do this briefly for under a second. But note it takes

about 15 seconds for the two units to internally connect and recognize each other. (During this 15

seconds it seems that one and only one keypress of the Tx unit will be recognised. Just disregard

this. Wait the full 15 seconds until the two units have connected. Do not press the LEARN button

again. Just wait 15 seconds.)

Tx units attached to any Rx unit can be unattached by pressing the LEARN button continuously for

8 seconds. The VALID DATA LED is on during these 8 seconds. As soon as the LED goes off

then you know that all Tx units previously recognized by the Rx unit have now been unattached

from the Rx unit.

We sell Tx units separately as QA16TX

The article makes reference to assembling the remote control Tx units. However, it is supplied

here fully assembled, tested, with a battery included and ready to go.
