WARNING: This guide is based on typical features of Thomson/Thomson-branded Bluetooth digital alarm clocks of the BTC2138 family and general consumer-electronics best practice.

The steps and troubleshooting below are designed to be safe and practical for most users.

1. First Look: What’s in the Box?

Before diving into the manual instructions, ensure you have all the components. Inside the box for the Thomson BTC2138, you should find:

The main unit (Alarm clock radio)
AC power adapter (DC input, usually 5V/1A)

USB Charging

Plug USB cable into the rear USB port. Charging works even when clock is in standby.

5. Bluetooth Pairing (Streaming Audio)

This is where the Thomson BTC2138 shines. Unlike old clock radios, you can stream podcasts or Spotify playlists.

To pair your phone/tablet:

Press the "MODE" button on the top of the unit until the display shows "BLUE" (or a Bluetooth symbol).
The display will likely start flashing a pairing indicator.
On your phone, go to Settings > Bluetooth.
Scan for devices. Look for "Thomson BTC2138" or "BTC2138 Audio".
Select it. You will hear a confirmation chime. The Bluetooth icon on the clock will stop flashing and remain solid.
Adjust volume using the VOL +/- on the clock or your phone.

Troubleshooting Bluetooth:

Can't connect? In Bluetooth mode, press and hold the "PLAY/PAUSE" button for 5 seconds to force a new pairing search.
Range? The manual specifies a range of approximately 10 meters (33 feet) line-of-sight.

Sleep timer

Press Sleep to set automatic turn-off time (commonly: 15/30/60/90/120 minutes). Each press cycles available durations; the display will indicate remaining sleep time.
