INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of door, at a minimum 
height of 5' (1.5 m) where small children cannot reach, 
away from moving parts of door and door hardware. If 
installing into drywall, drill 5/32" holes and use the anchors 
provided. For pre-wired installations (as in new home 
construction), it may be mounted to a single gang box 
(Figure 1).
NOTE: The functional temperature range of the door 
control is between -4° F (-20° C) and 122° F (50° C). 
Scroll speed of display is slower at lower temperatures 
although the door control remains fully functional.
CAUTION: Continuous exposure of the door control to 
temperatures below -22° F (-30° C) may damage the LCD 
screen.
SPECIAL NOTE: Only one 398LMC can be connected to 
each garage door opener. If additional wall controls are 
desired to operate the same garage door opener, it is 
recommended to use model 378LMC wireless wall control 
as the secondary door control. 
1.  Strip 7/16" (11 mm) of insulation from one end of bell 
wire and connect to the two screw terminals on back of 
door control by color: white wire to the W (2) and white/
red wire to the R (1) (Figure 2).
2.  Remove push bar cover by gently prying at the lower/
middle portion of the cover with a small flat-head 
screwdriver. Fasten with 6AB x 1-1/4" self-tapping 
screws (drywall installation) or 6-32 x 1" machine 
screws (into gang box) as follows:
 • 
 
Install bottom screw, allowing 1/8" (3 mm) to protrude 
above wall surface.
 • 
 
Position bottom of door control on screw head and 
slide down to secure. Adjust screw for snug fit.
 • 
 
Drill and install top screw with care to avoid cracking 
plastic housing. Do NOT overtighten. 
 • 
 
Replace cover by inserting top tabs first and then snap 
cover in place.
3.  (For standard installations ONLY) Run bell wire up 
wall and across ceiling to motor unit. Use insulated 
staples to secure wire in several places. Do NOT pierce 
wire with a staple, creating a short or open circuit.
4.  Strip 7/16" (11 mm) of insulation from end of bell wire. 
Connect bell wire to the quick-connect terminals on the 
motor unit: white to white and white/red to red
(Figure 2).
NOTE: If you have any trouble with the operation of the 
buttons, loosen the top mounting screw. DO NOT connect 
power and operate the opener at this time.The trolley will 
travel to the full open position but will not return to the 
close position until the sensor beam is connected and 
properly aligned.
To prevent possible SERIOUS INJURY or DEATH from 
electrocution:
•  Be sure power is not connected BEFORE installing door 
control.
•  Connect ONLY to 24 VOLT low voltage wires. 
To prevent possible SERIOUS INJURY or DEATH from a closing 
garage door:
•  Install door control within sight of garage door, out of reach 
of children at a minimum height of 5 feet (1.5 m) and away 
from ALL moving parts of door.
•  NEVER permit children to operate or play with door control 
push buttons or remote control transmitters.
•  Activate door ONLY when it can be seen clearly, is properly 
adjusted and there are no obstructions to door travel.
•  ALWAYS keep garage door in sight until completely closed. 
NEVER permit anyone to cross path of closing garage door.
