Important Safety Instructions

The manual lists several safety rules for proper use:

• Read all instructions before using the coffeemaker.
• Do not touch hot surfaces. Use handles or knobs.
• Do not immerse the cord, plug, or coffeemaker in water or any liquid.
• Close adult supervision is required when used near children.
• Turn the appliance off and unplug it when not in use and before cleaning.
• Allow parts to cool before removing, installing, or cleaning them.
• Do not use the unit with a damaged cord, damaged plug, malfunction, or physical damage.
• Do not use outdoors.
• Keep the cord away from table edges, counters, and hot surfaces.
• Do not place the coffeemaker near a hot gas burner, electric burner, or heated oven.
• Place it on a hard, flat, level surface to maintain airflow underneath.
• Do not use it for anything other than its intended household use.

The manual warns that scalding may occur if the lid is removed during the brewing cycle.

Decanter Use and Care

The glass decanter is designed only for this Oster coffeemaker. To reduce the risk of breakage:

• Do not use the decanter on a stovetop.
• Do not place it in an oven or microwave.
• Do not set a hot decanter on a wet or cold surface.
• Do not use a cracked decanter.
• Do not use a decanter with a loose or weakened handle.
• Do not clean it with steel wool, abrasive cleaners, or harsh pads.
• Discard the decanter if it ever boils dry.
• Protect it from scratches, sharp blows, and rough handling.

Power Cord and Plug Instructions

The coffeemaker comes with a short power cord to reduce tripping or tangling risks. An extension cord may be used carefully if needed.

If using an extension cord:

The coffeemaker uses a polarized plug. If the plug does not fit fully into an outlet, reverse it. If it still does not fit, contact a qualified electrician. Do not modify the plug.

The manual also explains that the cord length can be adjusted by gently pulling out more cord or feeding extra cord back into the coffeemaker slot.

Before First Use

Before brewing the first pot of coffee, clean the coffeemaker.

Steps:

1. Wash the decanter, decanter lid, filter basket, and permanent filter with mild detergent and water.
2. Rinse all parts thoroughly.
3. Replace all parts and close the lid.
4. Run one brew cycle using water only.
5. Do not add coffee during this cleaning cycle.
6. When brewing is complete, turn the coffeemaker off.
7. Discard the water.
8. Rinse the decanter, lid, and filter basket.

After this process, the coffeemaker is ready for normal use.

How to Set the Clock

This applies to programmable models.

1. Plug the power cord into a standard electrical outlet.
2. Press the PROG button.
3. The word “CLOCK” appears on the display.
4. Press and hold the TIME button until the correct current time appears.
5. Check the AM/PM indicator on the left side of the display.

Holding the TIME button for 3 seconds speeds up time adjustment. Holding it for 10 seconds speeds it up further.

To check the programmed brew time, press the PROGRAM button until “TIMER” appears.

Coffee Measurement Guide

The manual recommends using one level tablespoon of ground coffee per cup. Use medium grind coffee for best results.

One level tablespoon equals about 5 g / 0.17 oz / 15 ml. One cup equals 5 fl. oz. of brewed coffee. Users may adjust the amount based on taste.

How to Add Water and Coffee

1. Open the filter basket lid.
2. Remove the filter basket if needed.
3. Place a 10–12 cup paper cone-style filter or the permanent filter into the filter basket.
4. If using a paper filter, make sure it fits flush against the basket sides.
5. Add the desired amount of ground coffee.
6. Shake gently to level the coffee.
7. Fill the decanter with fresh cold water to the desired number of cups.
8. Pour water into the reservoir.
9. Do not fill past the MAX line.
10. Close the lid.
11. Place the empty decanter fully on the warming plate.

The manual warns that if the decanter is not properly positioned, water and coffee grounds may overflow from the filter basket.

How to Brew Coffee Now

1. Add water and coffee as directed.
2. Make sure the decanter and filter basket are properly in place.
3. Press the AUTO/ON/OFF button.

To turn the coffeemaker off manually, press the AUTO/ON/OFF button until the light turns off.

How to Use Pause ’n Serve

The Pause ’n Serve feature allows a cup of coffee to be poured before the full brew cycle finishes.

Important rule:

• Replace the decanter on the warming plate within 30 seconds.

If the decanter is removed for more than 30 seconds, coffee may overflow from the filter basket and cause burns or property damage.

1. Press the STRONG BREW button once.
2. The blue Strong Brew light turns on.
3. The coffeemaker uses the selected Strong Brew setting.

The machine remains in the selected brew strength until changed or unplugged.

3. Press PROG twice until “TIMER” appears.
4. Press TIME to set the desired brew time.
5. Press PROG once or wait 10 seconds.
6. Press AUTO twice to activate Delay Brew.
7. The Auto light flashes until the programmed time is reached.
8. At the selected time, the light turns red and brewing starts automatically.
9. Select Strong Brew if desired.

For safety, the coffeemaker will not automatically start again the next day unless Delay Brew is set again with fresh coffee, water, and filter.

Regular Cleaning and Descaling

Minerals in water can leave calcium deposits inside the coffeemaker and affect brewing performance. The manual recommends cleaning with white household vinegar.

Descaling steps:

1. Pour 4 cups / 20 fl. oz. of undiluted white vinegar into the water reservoir.
2. Place an empty 10–12 cup basket-style paper filter or permanent filter in the filter basket.
3. Close the reservoir lid.
4. Place the empty decanter on the warming plate.
5. Brew 3 cups of cleaning solution through the coffeemaker.
6. Turn the coffeemaker off.
7. Let it stand for 30 minutes.
8. Run the rest of the vinegar solution through the coffeemaker.
9. Discard the cleaning solution.
10. Rinse the decanter thoroughly.

Cleaning the Decanter

Hard water can leave a white stain on the decanter. Coffee may turn this stain brown.

To clean decanter stains:

1. Fill the decanter with equal parts water and vinegar.
2. Let the solution stand for about 20 minutes.
3. Discard the solution.
