How to Change the Time on an iHome Clock Radio

To change the time on an iHome clock radio, enter its clock-setting mode, adjust the time with the setting buttons or dial, and confirm the new setting. The controls depend on the model: an iPL23 uses a different procedure from an older hotel clock with hidden rear buttons. Start by matching your clock to the controls below, then follow the appropriate instructions.

Identify Your iHome Clock’s Controls

Match the controls on your actual clock; hidden hotel-clock controls are not universal.

Read the model number on the product label, usually on the underside or back, before choosing a procedure.

Also distinguish the current clock time from the alarm time. An Alarm button changes when the alarm sounds, not the time the clock keeps.

How to Change the Time on Your iHome Clock Radio

Your Clock or Control Layout	Adjustment Method
Model label identifies an iPL23	Select manual mode, then use the setting buttons
Older hotel clock with top discs and covered rear time controls	Use the rear clock-adjust control and right-hand top disc
Another model or a layout that does not match either description	Use instructions matched to the exact model; do not assume either sequence applies

Step 1: Power the Clock and Locate the Time Controls

For the iHome iPL23 stereo FM clock radio for iPod or iPhone, keep the clock connected to its normal power supply. Use the included AC adapter, which accepts 100V–240V AC input, according to iHome’s iPL23 instruction manual. Confirm that input range on the adapter label; it is not a universal specification for every iHome adapter.
Locate the controls for your model. On the iPL23, identify the time-setting button and the +/– setting buttons on the top panel. On the older hotel design, look behind the removable horizontal rear bar for controls labeled TIME ZONE and CLOCK ADJ.

If the hotel clock’s rear bar has a retaining thumbscrew, loosen it to release the cover. Remove only the control cover, not the clock’s housing. If it will not release easily, ask hotel staff rather than forcing it.

Step 2: Enter Manual Time-Setting Mode

For the iPL23:

Press and hold the Time Sync/Time Set Button until “MAN” or “SYNC” flashes.
If “SYNC” appears, press the + or – setting button until “MAN” appears. This selects manual time setting.
Press and release the Time Sync/Time Set Button. The clock time will flash.

Selecting manual mode first matters: a flashing “SYNC” display is not yet the screen where you change the time.

For the older hotel clock:

Press and hold CLOCK ADJ until the clock beeps and the time display blinks.
Release the button once the time is blinking.

Step 3: Adjust the Displayed Time

For the iPL23, press the + or – setting buttons to move the displayed time to the correct value.

Do not use the iPL23’s separate volume controls to adjust the time.

For the older hotel clock, rotate the right-hand disc on top of the clock to move the time backward or forward while the display is blinking.

Check the hour, minutes, and any AM/PM indicator before saving. Matching the digits is not enough if the clock is set to the wrong half of the day; that can make an otherwise correctly programmed alarm sound at the wrong time.

If the hotel clock’s disc changes only the volume, the clock probably has not entered clock-setting mode. Stop turning it and check the control layout.

Step 4: Save the Time and Close Any Control Cover

For the iPL23, press and release the Time Sync/Time Set Button to confirm the time setting.

Listen for two beeps confirming that the iPL23 has saved the time and exited time-setting mode.

Do not assume that a flashing display means the setting has been saved.

For the older hotel clock:

Press CLOCK ADJ repeatedly until the normal time display returns.
Confirm that the displayed time is correct.
Refit the rear control bar and secure its retaining fastener, if fitted.

For either clock, finish with the regular clock display showing steadily, not an alarm-setting screen or a flashing adjustment field.

Correct a Daylight Saving or Time-Zone Error

If the minutes are correct but the hour is wrong, check for a daylight saving or time-zone mismatch before resetting the clock. These controls are particularly relevant to older hotel units.

Use the Older Hotel Clock’s DST Switch

On the older hotel design equipped with a DST selector, the switch is behind the removable rear bar.

Compare the display with a reliable source of local time and determine whether a daylight saving adjustment is needed.
Remove the rear control cover and locate the DST switch, if present. Its positions are AUTO, OFF, and +1.
The +1 position advances the displayed time by one hour. Use that advance when needed for daylight saving, without also manually advancing the clock.
If an unwanted daylight saving advance is making the clock run ahead, select OFF and compare the display with local time again.
Once the display is correct, refit and secure the rear cover.

Do not change both the base clock time and the daylight saving setting to correct the same offset. That can leave the clock wrong again when the selector changes.

Check the Time Zone Without Guessing at Codes

A larger hour difference, with the minutes still correct, can indicate a time-zone mismatch. On an older hotel clock, the TIME ZONE control may also be hidden behind the rear bar.

Ask hotel staff to select the local zone and confirm the normal time display before replacing the cover. Daylight saving and time zone are separate settings, so one should not be used to compensate for the other.

Troubleshoot an iHome Clock That Won’t Change Time

The Time Never Starts Flashing

First, hold the clock-setting control. Then confirm that the clock has power.

On the iPL23, a flashing “MAN” or “SYNC” is the mode-selection stage. Select manual mode and press the time-setting button to make the actual time flash before adjusting it.

If the correct control still produces no response, avoid trying unrelated button combinations. Record the model number and check whether a hotel unit’s adjustment controls are accessible.

Turning the Volume Dial Does Nothing

A dial can have different functions depending on whether the clock is in normal operation or setting mode. On the older hotel layout covered here, the right-hand top disc adjusts time only after clock adjustment has been activated.

If the time is not blinking, the dial is not ready to change it. If it is blinking but the dial still does nothing, stop and recheck the controls. Do not force the dial.

The Clock Returns to the Wrong Time

Watch when the change happens:

Immediately after setting: The setting may not have been confirmed.
After a power interruption: The backup battery may no longer be retaining the clock settings.
After synchronization or a seasonal change: Check the setting associated with that change.

Repeatedly changing the digits will not solve a depleted backup battery, and replacing a battery will not correct the wrong time zone.

The Clock Loses Its Settings After an Outage

For iHome’s iPL23, the backup battery is a CR2450, used to preserve clock settings and support alarm operation during a power failure. Confirm that battery type in the iPL23 battery compartment or instruction manual before replacing it; other models may use different batteries.

If replacement is needed, install the correct battery with the polarity shown in the compartment and secure the battery cover. Restore normal power if it was disconnected, set and save the current time, and check the alarm settings.

Unplugging the clock alone is not a dependable way to erase its settings.

Confirm the Time and Keep It Correct

Before relying on the clock for your next alarm, check that:

The display matches a reliable source of local time.
The clock continues advancing normally.
The alarm time, enabled status, and wake-up source are correct.

Verify that an alarm is enabled and will use the sound source you expect.

Keep the model number handy so the next adjustment does not start with guessing at buttons. If the clock becomes wrong again, note whether it followed an outage, synchronization, or a daylight saving change; that tells you which setting or component to address next.

Frequently Asked Questions

How Do I Reset My iHome Alarm Clock?

There is no single factory-reset sequence for every iHome alarm clock. Unplugging may not erase the settings because the backup battery can retain them, including on the iPL23. Use the reset procedure for the exact model only if needed, then reenter the time and alarm settings and verify the normal display before relying on it.

How Do I Manually Update the Time and Date?

The date-setting procedure depends on whether your model has a calendar function. A time-only adjustment does not necessarily change the date, and an alarm’s weekday selection is not the same as setting the calendar. To change the clock time manually, enter time-setting mode, adjust the displayed time, and confirm the setting.

How Do I Set the Time on an iHome HBN22, HT160, or iDL46?

For an HBN22, HT160, or iDL46, first confirm the model number on the clock’s label, usually on the underside or back. Neither the iPL23 sequence nor the older hotel-clock dial method should be assumed to work on those models. For a hotel clock with inaccessible controls, ask staff to set the local time rather than opening the housing or trying an unrelated reset.

Can I Switch My iHome Between 12-Hour and 24-Hour Time?

Some iHome models support both 12-hour and 24-hour displays, but the selection method varies. Use the time-format control specified for your model rather than trying an unverified button combination. After changing formats, confirm both the current time and the alarm time.
