Good morning, my name is ***** ***** will assist with your query today.
Firstly can you confirm the replacement batteries you have used in the remote are lithium CR2025?Once you have verified the correct batteries are being used, I would also try cleaning the IR sensor on the device, which can be found on the bottom left of the CD compartment next to the RDS logo, and using the remote within 1M of the sensor.If this fails due to the construction of the remote there isnt really an option to repair it, and would most likely be uneconomical to repair. Due to the age of the unit replacement remotes do not seem readily available, however a universe remote should be sufficient, such as this one here for under £12.
Good evening, I just wanted to check if I can be of any more assistance.
