Change battery sign.Sky+ box

Just installed my new sky+160 box.The only probllem is when i change channels the battery sign is always there.The batterys are brand new,also changed them and tried some other new ones.Still same problem.
Anyone help.

 

Might be the sensor which reads the remotes signal strength is faulty, a reboot (which I suspect you've tried) might help.

 

Have done housekeeping and has sorted it.

thanks for reply Starburst.
