1. Unscrew the base plate
2. Remove the battery carefully pushing it out the battery holder towards the middle of the PCB
3. Install a new battery Positive (+) facing upwards.
4. Test the unit is operating before closing the housing the unit should beep when the button is pressed
Mount the unit in an upright position with the SHERLOTRONICS logo facing the bottom.
Avoid mounting on Metal surfaces and near High Power cables. If mounting in a shower or very wet
environment, apply a small amount of silicone over the screw holes to seal the unit completely.
Please follow the relevant Receivers Installation instructions to programming the unit to a receiver.
The WMTX is compatible to the following Receiver models:
Model: RX1-150; Model: RX2-150; Model: Rx3-150; Model: RX1-500
Model: RX4-500; Model: MB4000
Please Note: Only for Models manufactured Nov 2016 onwards.
If your are learning the WMTX into an Old generation receiver and it does not want to program in then you can
revert the WMTX unit to transmit out our Old generation Receiver code.
Follow this procedure to configure the unit with the Old code:
1. Open the WMTX unit up and remove the battery.
2. While pressing in the button, insert the battery and keep pressing the button for about 10 seconds.
The WMTX will then beep when it is ready.
1 Beep = Old Code
2 Beeps = New code
You can alternate between the old code and the new code by following the procedure above.
CAUTION:
RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED
BATTERIES ACCORDING TO INSTRUCTIONS.
Location & Mounting
Replacing the Batteries
The unit is supplied with a CR2450 3V Lithium battery. The battery is rated at 610mA/h. The WMTX will be able
to transmit over 40 000 times before the battery is depleted. The unit will loose RF performance when the battery
reaches below 2.6V DC. It is best to change the battery every 3 years if not used very often for instance if it is
used as a PANIC button. If the unit is used as a Door opener in a busy office environment then we would
recommend replacing the battery every year.
