A drill template is enclosed in the kit. Mount the drill template to the front of the aircraft instrument panel.
Punch the two holes in the drill template for the Mode and Step Switch. Remove the drill template and drill
the two holes using a 1/4" drill bit. You may want to drill a pilot hole first.

Install the instrument from behind the instrument panel using 6 x 32 screws. DO NOT USE SCREWS
THAT PENETRATE THE INSTRUMENT FRONT PANEL MORE THAN 1/8", DOING SO WILL
BREAK THE GLASS DISPLAY.
Connect all the Circular Connectors to the UBG in the following manner:
A) Push the two mating connectors together and twist them until they snap into position.
B ) Turn the locking ring on the instrument connector clockwise (1 1/2 turns) until it locks into position.
If you are using the optional remote head for the UBG-16, secure the body of the UBG-16 underneath the
instrument panel in a location that will not obstruct the freedom of travel of any controls. Route the wires
from the body to the remote head making sure that the wires do not obstruct the freedom of travel of any
controls. Connect the cable from the head to the body.

To configure the UBG to operate with the temperature probes and Functional modules installed in your
aircraft, refer to the Power-up Programming section in the Operating Instructions. Use the Configuration
Form found in this manual as a reference.

A. Turn the master switch on and look for a near ambient temperature reading on each temperature channel.
If the instrument does not power-up (display a reading), check the power and ground leads (red and black
leads) for an open, loose or poor connection.
If you suspect that any channel is not receiving a signal, remove the probe from the engine (leaving it
connected to the Extension Cable) and apply a temperature to it. Look for an increase in reading on the
display for that channel. Check the other channels for an increase in reading. You may have connected
the probe to the wrong Extension Cable. If the reading is decreasing, you may have reversed the connec-
tors on the Extension Cable leads (the yellow wire on the probe must connect to the yellow wire on the
Extension Cable).
B. Start the engine and check each channel for a proper reading. On the ground (after a few minutes)
EGT’s will read around 900°F and CHT’s will read around 200°F If you suspect any channel is not
receiving a signal properly, see step A of the “Troubleshooting” section of this manual.
