Remotes normally handle basic radio and alarm controls—power on/off, volume, tuning, station presets, alarm set/disable, snooze and sleep timers. They can be IR or wireless; some remotes are designed for vibrating or wireless activation with multiple intensity settings and an operating range of several feet.
Tuning is usually digital AM/FM, and preset counts vary by model. Examples found in product specs include 10 presets (5 AM/5 FM), 18 presets (9 AM/9 FM), 10 AM + 10 FM, and 20 AM + 20 FM—check the model listing for its exact preset capacity.
Clock radios often include built‑in speakers with manufacturer‑listed wattage and physical driver details. Common sound controls include loudness, bass and treble adjustments, and in some models bass‑reflex tuning; frequency response and stereo vs. mono configurations are sometimes specified in the product information.
Sizes vary from compact bedside units to larger tabletop systems. Example ranges from product listings: heights about 4.02–7 inches, widths about 6.16–18.88 inches, depths about 2.38–7.13 inches, and weights roughly 1.1–4.2 pounds.
Many models include sleep timers and snooze buttons plus programmable playback options. Where applicable, clock radios with CD players may offer programmable CD memory and playback modes such as repeat and random, and timed shutoff for automatic power‑down.
