user’s manual. Do not mix old and new batteries as the old ones may leak.
Troubleshooting for losing Signals
If without obvious reasons the display for particular channel suddenly goes (---) dash, check:
• The remote unit of that channel is still in place.
• The batteries of both receiving and remote unit. Replace as necessary.
• The transmission is within range and path is clear of obstacles and interference. Shorten the distance when
necessary
• Signals from other household devices, such as bell, home security system and entry controls, it may
interfere with those of this product and cause temporarily reception failure. This is normal and it doesn’t
affect the general performance of the product. The transmission and reception of temperature reading
readings will resume once the interference recedes.
