Battery Replacement
Your Ungo Remote Transmitter uses a 12 volt alkaline battery, which will need to be replaced
from time to time. Under normal conditions, the battery may last for up to a year before it needs
replacement.
When your Remote Transmitter's battery is in need of replacement, you will notice a decrease in
your system's operating range or a decrease in the brightness of the Transmitter's LED indicator.
To change the battery, remove the 2 screws at the back of the Transmitter and carefully separate
the top and bottom halves of the Transmitter case.
Insert the new battery, making sure that the positive and negative terminals are positioned
correctly and replace the cover.
Adding a New Transmitter into the System
The Ungo MS2004 has the ability to recognize up to four individual Remote Transmitters. If the
vehicle is used by multiple drivers, each can have their own Remote Transmitter.
To add a Remote Transmitter:
1. Turn on the ignition.
2. Press and hold the Override switch.
• The status LED will turn on red.
• The siren will chirp 5 times.
3. Have all desired transmitters ready and within 5 seconds follow the steps below for
each transmitter.
For remote arming with chirp confirmation continue holding the Override switch and
press Transmitter Button 1.
--- or ---
For remote arming without chirp confirmation release the Override switch and press
Transmitter Button 1.
• The status LED will flash once quickly to confirm that the new Remote Transmitter
has been added.
4. Turn off the ignition.
• The siren will chirp 3 times.
Deleting Transmitters (Adding a Remote Transmitter and Erasing All
Other Remote Transmitters From the System)
Code all memory locations to delete any lost transmitters. Example: if two transmitters are used,
after coding the first transmitter, code the second transmitter three times to fill up the remaining
memory locations.
