- Recalling a Station: Press the MEMORY button, then use the tuning knob or arrow buttons to navigate through stored stations.
- Deleting a Station: Tune to the station you wish to delete. Press the DELETE button. Confirm deletion if prompted.
4.6 Alarm and Timer Functions
The radio includes an alarm function and broadcast timing. Refer to the display and the ALARM and TIME buttons for setting these features. Detailed instructions for setting the alarm and broadcast timer are typically found in the full product manual (if available).
4.7 Using Earphones
Plug 32Ω stereo earphones into the headphone jack on the side of the radio for private listening and to enjoy FM stereo broadcasts.
5. Maintenance
- Cleaning: Wipe the radio with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Care: If the radio will not be used for an extended period, remove the batteries to prevent leakage and damage.
- Storage: Store the radio in a dry place, away from extreme temperatures and direct sunlight.
