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

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.
