2.1.2.1 Keypad Overlay
When changing the keypad type setting, it is recommended to change the keypad overlay sticker on
the unit as well. This will ensure that the operator knows which buttons are the function buttons and
which buttons are used for either ON/OFF or START and STOP. The following procedure should be
used to change the keypad overlay. If the unit does not have an overlay, start at step 4.
1. Remove the old overlay.
2. Wipe the unit down with rubbing alcohol to remove any adhesive that is still on the unit.
3. Let the unit dry.
4. Remove the backing from the new overlay.
5. Align the overlay with the bottom of the inset for the keypad.
6. Slowly place the overlay over the buttons ensuring that the overlay makes contact around
each of the buttons.
7. Firmly press the entire overlay to ensure that it seals the unit to maintain sealing.
2.1.3 Remote Pairing
Enter the transmitter function setting mode by moving the function dip-switch
located inside the battery compartment to the on position. Reinsert the two
batteries and press PB1 to power up the transmitter. At this point the Status
LED will display a series of red, green, and orange blinks showing the current
software version. Then press and hold PB3 and PB4 at the same time for up
to 1.0 second to go into the remote pairing mode (Status LED orange and then
off).
TX to TX Pairing:
Output data original transmitter
Receiving data new transmitter
(Press and hold PB3)
(Press and hold PB4)
After entering the remote pairing mode, output data by pressing and holding PB3 on the original
transmitter and receive data to the new transmitter by pressing and holding PB4 at the same time.
The pairing is completed when the Status LED on the new transmitter (the unit receiving the data)
turns to constant green while the buttons are still pressed down. Exit the transmitter function setting
mode by taking out the batteries and move the function dipswitch on both transmitters back to the off
position.
