operational. Plug your landscape lighting or low voltage transformer into one of the outlets (G) on the timer.

battery indicator appears.

•  Change batteries within one minute of unplugging to 

keep settings.

up with a small flat screwdriver. Install the new batteries

TROUBLESHOOTING GUIDE

Problem

Probable Cause

Solution

The battery symbol always shows in the upper 

right of the display when plugged in or no display 

at all when unplugged and buttons are pressed. 

Please note that the battery display takes 1 minute 

to recognize installed or removed batteries.

The batteries are either:

•  Low
•  Not installed
•  Not installed correctly
•  Still have the pull tab
•  Poor contact in the battery holder

•  Remove the pull tab, if present. 
•  Verify the battery polarity per the outline 

on the inside or “+/-” on the outside of the 

battery holder. 

•  Bend the contacts of the battery holder to 

touch the batteries firmly. 

•  Replace both batteries. Use two type LR44 

or A76.

The timer switches at the incorrect times or skips 

some of the programmed times.

Programmed schedule(s) are incorrect.

Press 

PROG

 to review the settings and revise them 

as necessary. See the instructions included with 

this manual.

The lights or controlled devices do not match the 

programmed ON/OFF status immediately after 

setting the time or programming a schedule.

The timer does not “catch up” automatically to the 

programmed load state. The status of the timer will 

remain as is until it comes to the next programmed 

ON/OFF time.

After programming your events or the time, push 

the 

ON/OFF

 button to change the load state, if 

necessary.

The timer shows ON but the light or other 

controlled device is off.

The light or controlled device itself may be 

switched off or the light bulb may be burned out.

Make sure the light or controlled device is switched 

on and plugged in or replace the light bulb.
