Troubleshooting

1. If a particular Module won't go on or off from the buttons on the Mini Timer:
Check that you have power to the outlet controlling the Module and the switch on the light
or appliance is ON.
Check that the Unit Code and Housecode on the Module are set correctly.
Try plugging the Module and the Mini Timer into the same outlet. If the Module doesn't
work in ANY outlet, not even with the Module and the Mini Timer in the same duplex
receptacle (top and bottom) the Module may be defective. Contact www.x10.com/support if
you need help.
2. If you can't control ANY Modules from the Mini Timer.
Check that there is a time displayed on the Mini Timer and that you have power to the
outlet it is plugged into.
Check that the Housecode for the Mini Timer is set correctly (see page 13). Try plugging
the Module and the Mini Timer into the same outlet. If NONE of your Modules work in ANY
outlet, not even with the Module and the Mini Timer in the same duplex receptacle (top and
bottom) the Mini Timer may be defective. Contact www.x10.com/support if you need help.

Intercom systems

Intercom systems which send voice signals over existing electrical wiring may interfere with
the operation of the Mini Timer when the intercom is in use. If the Intercom system has its
own separate wiring it will not cause a problem.

Power interruptions

When the power is restored after an outage, Lamp Modules and Wall Switch Modules will
normally be OFF. Appliance Modules have a "latching relay mechanism" and will stay as
they were before the interruption.
This means that when you fi rst plug in an Appliance Module which you have just
purchased, it may in an ON or OFF state (the state it was in before unplugging it after
factory testing).

Battery backup

If you install two AA alkaline batteries in the battery compartment of the Mini Timer your
programmed times will be protected for up to 48 hours in the event of a power outage. The
backlight and the buzzer do not operate when the unit is running on the backup batteries.
Battery indicator
If the batteries are low, dead, or not installed, the low battery indicator will be shown in
the display. It is recommended that you check the condition of the batteries regularly and
replace them at least once every 6 months.
