Hi @Colin GP you may also wish to look at the Samsung page for this model https://www.samsung.com/uk/audio-devices/soundbar/2-1-ch-soundbar-black-mist-hw-r450-xu/ which includes the manual.
Should you wish to connect via Bluetooth:
Press the PAIR button on the remote control to enter the “BT PAIRING” mode.
(OR) . Press the (Source) button on the right side panel and then select “BT”.
“BT” changes to “BT READY” in a few seconds automatically if there is no Bluetooth device
connected to the Soundbar.
b. When “BT READY” appears, press and hold the (Source) button on the right side panel
of Soundbar for more than 5 seconds to display “BT PAIRING”.
2. Select Bluetooth mode on the TV. (For more information, see the TV’s manual.)
3. Select “[AV] Samsung Soundbar R4-Series” from the list on TV’s screen.
An available Soundbar is indicated with “Need Pairing” or “Paired” on the TV’s Bluetooth device
list. To connect the TV to the Soundbar, select the message, and then establish a connection.
• When the TV is connected, [TV Name] → “BT” appears on the Soundbar’s front display.
4. You can now hear TV sound from the Soundbar
