Oregon Scientific RM318PA Troubleshooting

Released Pre-Fall 1997, identified by model number RM318PA

Projector switch does not remain in “on” position ¶ 

The projector switch moves back to the "off" position when moved to the "on" position.

The On/Off switch is broken. ¶ 

To replace the On/Off switch, hold the clock so that the clock face is away from you. Use your thumbs to push up on the battery cover. Take the battery cover off of the clock. Pull down on the AC Adapter Jack to remove the jack. Use one hand to stabilize the clock while the other hand pushes the batteries toward the spring. Pull the batteries out at an angle, one at a time. Use a Spudger to pry off the silver casing on the back, prying at the top where the casing connects to the clock. Once the back is open at the top, pry at the side of the clock closest to the battery compartment. On/Off switch should come off with the casing. Insert the new switch into slot. Push in until you hear a "click." Replace the back of the clock by pressing the cover back into place. For step by step instructions, click link: Oregon Scientific RM318PA Power Switch Replacement

The Projection Clock itself is not in sync. ¶ 

The unit can be synchronized by resetting the batteries. Resetting process: Remove the batteries and disconnect the adapter for fifteen (15) minutes. Reinstall the batteries and reconnect the adapter. Hold the reset button for five (5) seconds located in the battery compartment or on the back of the unit. (A paper clip or pin will be needed to fit into the hole for the reset button.) For step by step instructions, click link: Oregon Scientific RM318PA Reset

The unit will not power on with batteries ¶ 

When the clock is turned on without the AC adapter, the clock will not power on.

The batteries need replacing. ¶

Clock will not power on when plugged in ¶ 

When plugged in with AC power adapter, the clock will not power on.

The AC power adapter needs to be replaced. ¶

With your other hand, pull down on the AC Adapter jack to remove. Remove batteries by pushing the battery toward the spring. Lift the battery out at an angle. Repeat with the second battery. Use a Phillips #00 Screwdriver to remove the four (4) screws from the back of the projection arm. Once screws are removed, lift the back up and off of the projection arm. Use a Phillips #00 Screwdriver to remove two (2) screws from back of projection arm. Use a Spudger to pry open the front of the projection arm casing. Start at the top of the projection arm. Once the top is partially open, use a thinner Spudger to pry at the side of the projection arm. Turn the clock on its side. Slide the focus wheel forward with your thumb. The Projection Beam and Focus Wheel Component should now be free of the Projection Arm. Hold the Component in one hand and lift the Projection Beam up and away from the Focus Wheel. The Lens is attached to the Focus Wheel and is now accessible for replacement purposes. For step by step instructions, click link: Oregon Scientific RM318PA Lens Replacement

Incorrect time display ¶

The time zone is unavailable. ¶ 

Only Eastern, Central, Mountain, and Pacific time zones are available. This clock does not function properly outside the continental United States.

The unit is not synchronized with the Atomic Clock. ¶ 

Please note: keep all the components within the same ten (10) feet radius while resynchronizing. In order to synchronize with the Atomic Clock, remove the batteries from main unit and all sensors. Unplug if on AC power. Allow a minimum of ten (10) minutes for any or all capacitors to discharge. Reinstall the batteries into any or all sensors first. Press a paper clip or pin into reset hole in the battery compartment. Reinstall the batteries into the main unit. Press a paper clip or pin in reset hole in the battery compartment. Wait up to ten (10) minutes for the unit to completely resyncronize. For step by step instructions, click link: Oregon Scientific RM318PA Reset

My clock projection led numbers are broken can this be fixed

Yes it can. In my case the "hot bar" connection to the display got faulty. You need to "re-hot" it carefully with a soldering iron. You can do it as follows (the blogpost and video are in german but you should get the picture).

I have owned several of these clocks over the years. This one I've only had about a year or so and it won't project anymore. That's why I've replaced my old ones, but this isn't very old.

My projection on the wall or ceiling reads backwards. Is there a way to fix it?

To reverse its reading simply press the snooze/light button and press again within 8 seconds and reading will be reversed.
