Special applications Because of it's unique "hard contact" switch feature, your timer may be used for applications not previously possible for electronic wall timers, such as use with dimmers, use without utility power, use on circuits other than 120 volts, controlling relays or contactors, or to control DC voltage (for example in recreational vehicles). See instructions above for dimmer applications. Replace device if NoOp will not clear from display. Make sure timer display shows `ON' then check dimmer operation at full brightness setting. If timer control is required at very low brightness settings, use a premium quality dimmer that can be turned on when set low. Recheck wiring, especially for the jumper, per "Installation Instructions - 3-Way Switch" and "Other Installations". Eliminate condition, replace the buried cable, do without the remote switch, or consult factory for other options. If the problem persists with the red wire disconnected or with a `remote' switch temporarily connected right at the timer, replace the defective timer, otherwise try the above remedies. Line up tabs on bottom of holder with notches in timer housing when pushing in. Straighten bent contact tabs. M+ (minute) button MODE ON/OFF EVENT RESET 4. Tuck the wires into the wall box leaving room for the timer. Using the screws provided, mount the timer to the wall box then install the wall plate.

[. . . ] Replace the battery when the digital display is dim, the message `lobAt' (Meaning LOW BATTERY) is displayed, or if the timer fails to operate. Press any button to clear the `lobAt' message. The timer has built-in memory protection providing at least 15 seconds to change a weak battery without losing your settings. You do not need to turn off the load or the power in order to replace the battery, however, do not attempt to switch the timer on or off while the battery is out or your settings will be lost and the timer will need to be reset. Display shows `no Op'. [. . . ]
