Electrohome USB Charging Alarm Clock Radio EAAC470 Manual

The electrohome USB Charging Alarm Clock Radio EAAC470 is a compact bedside alarm clock designed for dependable wake-up performance, everyday radio listening, and convenient USB device charging. Its automatic time-setting function, dual alarms, battery backup, adjustable display brightness, and indoor temperature readout make it suitable for bedrooms, guest rooms, offices, and dormitories.

The clock includes AM/FM digital tuning with up to 20 station presets, a sleep timer, gradual radio or buzzer alarm, calendar display, and optional weekend alarm skipping. A USB charging port supplies up to 1,000 mA for compatible smartphones and other small USB-powered devices. The included CR2032 battery preserves the time and date during a power interruption.

The EAAC470 is best suited to users who want a straightforward digital alarm clock radio rather than a Bluetooth speaker or smart-home device. It does not include Bluetooth, audio input, headphone output, or projection features, so it focuses on reliable bedside operation instead of advanced wireless connectivity.

Because Electrohome lists the model as discontinued, availability depends on remaining inventory, refurbished units, and third-party sellers. Typical prices vary by condition and seller, with used or refurbished examples generally costing less than comparable new clock radios. Confirm the model number, included power adapter, battery, and return policy before purchasing.

How to Set Up the Electrohome EAAC470 Alarm Clock Radio

Place the clock on a stable, dry surface near a suitable wall outlet. Keep ventilation openings clear.
Insert the included CR2032 battery into the backup compartment, matching the positive and negative markings.
Connect the supplied power adapter to the clock and then to a correctly rated wall outlet.
Allow the automatic time-setting function to complete. If the time is incorrect, use the clock and time controls to set it manually according to the button labels.
Set Alarm 1 or Alarm 2, choose radio or buzzer operation, select the wake-up time, and adjust the alarm volume.
Program AM/FM stations using the tuner and preset controls. The radio supports up to 10 AM and 10 FM presets.
Adjust display brightness to off, low, medium, or high. Use the sleep timer when listening before bedtime.
Connect a compatible USB cable to the charging port. Charging speed depends on the connected device and cable.

The EAAC470 does not support Bluetooth pairing, Wi-Fi, or wireless audio. For safety, use only the supplied or correctly rated adapter, keep liquids away from the clock, and do not operate it with a damaged cable. Do not attempt to open, modify, or repair the unit while it is connected to power.

Electrohome EAAC470 Troubleshooting Guide

The display is blank

Check that the adapter is firmly connected and that the outlet is working. If display brightness is set to off, use the brightness control to select low, medium, or high. Replace the CR2032 battery if the time is not retained during an outage.

The time resets after a power failure

Install a fresh 3 V CR2032 lithium battery with the polarity oriented correctly. The backup battery is intended primarily to preserve clock information and does not replace normal AC operation.

The alarm does not sound

Confirm that the desired alarm is enabled, the alarm indicator is visible, and the alarm time is set for the correct AM or PM period. Check whether weekend skip has been activated. Increase the alarm volume and verify that radio mode has a usable station.

Radio reception is weak

Move the clock away from televisions, routers, chargers, and other sources of electrical interference. Extend and reposition the power cord, which may help FM reception, and rescan or manually tune the station.

USB charging is slow or unavailable

Try another compatible cable and confirm that the connected device accepts charging from a standard 1,000 mA USB output. Avoid charging multiple devices through unapproved splitters or hubs.

No specific user-facing error-code system is identified for this model. If the clock remains unresponsive, disconnect power, remove the backup battery briefly, reinstall it, and reconnect the adapter. Electrohome’s standard warranty information describes 12 months of coverage from the purchase date, subject to its terms and exclusions. For support, use Electrohome’s official support or contact page and have the model number, serial information, proof of purchase, and troubleshooting details available.

Customer Reviews and Buying Advice

Faqs

How do I set up the electrohome USB Charging Alarm Clock Radio EAAC470 for the first time?

Connect the included AC adapter to the EAAC470 and a suitable wall outlet. The automatic time-set feature will display a time-zone number; use the time-zone controls to select your region, then confirm the setting. Set daylight-saving time if required, choose 12- or 24-hour format, and adjust the date. Finally, set Alarm 1 and Alarm 2, select radio or buzzer, and choose the desired schedule, such as weekdays, weekends, or the entire week.

Why is the time wrong on my electrohome USB Charging Alarm Clock Radio EAAC470?

An incorrect time usually results from selecting the wrong time zone, daylight-saving setting, or clock format during setup. With the radio off, check the selected time zone and DST option, then manually reset the time if necessary. Confirm that the AC adapter is firmly connected. The internal CR2032 battery preserves clock settings during a power outage, but it cannot correct an incorrectly programmed time and should be replaced if it is depleted.

How do I program two alarms on the electrohome USB Charging Alarm Clock Radio EAAC470?

Use the dedicated Alarm 1 or Alarm 2 button to enter the alarm-setting mode, then adjust the hour and minutes with the tuning controls. Select the alarm type—radio or buzzer—and choose a schedule such as Monday through Friday, Saturday and Sunday, or every day. Confirm that the alarm indicator is visible on the display. To disable an alarm later, press its corresponding alarm button until the indicator disappears.

What should I do if the EAAC470 alarm does not sound at the programmed time?

First verify that the clock shows the correct time and that the intended Alarm 1 or Alarm 2 indicator is enabled. Check whether the alarm schedule excludes the current day, then confirm that a radio alarm has a usable station selected and that the volume is audible. If the display is blank, reconnect the AC adapter. Reset the alarm time if needed, and replace the CR2032 backup battery if settings are repeatedly lost.

Can I charge my smartphone with the electrohome USB Charging Alarm Clock Radio EAAC470?

Yes. The EAAC470 includes a USB charging port designed to provide up to 1000 mA for compatible USB-powered devices. Connect your phone or another device with its own USB charging cable, then monitor charging performance because larger tablets or fast-charge devices may require more power than this port supplies. Charging may be slower than with a dedicated adapter. Keep the clock connected to AC power for reliable USB charging.

How can I improve AM or FM reception on the electrohome EAAC470?

For FM listening, fully extend and reposition the antenna wire, keeping it away from power adapters and other electronic equipment. For AM reception, rotate or relocate the clock radio to reduce interference from appliances, traffic, or nearby wiring. Use the tuning controls to find the clearest signal, then save strong stations to the preset buttons. If audio is distorted, lower the volume and try a different position before retuning.

How do I use the sleep timer and snooze functions on the EAAC470?

To fall asleep while listening to the radio, use the Sleep function and select the desired countdown period; the radio will turn off automatically when the timer expires. When an alarm sounds, press the Snooze button to pause it for approximately nine minutes. Repeated snoozing can delay the alarm several times, so use the alarm controls to stop it completely when you are ready to get up. Check the display to confirm the selected function.

How should I clean and maintain the electrohome USB Charging Alarm Clock Radio EAAC470?

Unplug the EAAC470 before cleaning, then wipe its cabinet and display with a soft, dry or slightly damp lint-free cloth. Do not spray liquid directly onto the clock, immerse it in water, or use abrasive cleaners. Keep ventilation openings clear and place the unit away from heat, moisture, and direct sunlight. If the clock loses settings during outages, replace the internal 3V CR2032 battery carefully and observe the correct polarity.
