Battery Replacement

• Factories indicates always operating, which is longer but based on about 20 ° C. All sensors, we can sell Swedish winters, and with good alkaline batteries is the least one year.

• We recommend that you replace each year in late autumn. So before the batteries are totally exhausted. The reason is that they are new batteries in top shape for winter pressures. And you are not the batteries run out so that you lose data and have to change the middle of winter.
• If you have any problems before the year has passed, check on the display if it indicates that the batteries are weak .. Some sensors are more sensitive than others for low battery voltage. Temperature Sensor is one such. The show often "OFL"

• Alkaline batteries are of good quality can chill well. What is absolutely necessary if located where it is cold.
• Rechargeable batteries are not only inferior properties when it gets cold. The voltage is not sufficient in most systems. (1.2 V to 1,5-1,6 V)
  
• At extremely low temperatures (below -30 ° C) is a special lithium battery used instead.
• Has an energy content that makes you not need to change so often.
• The risk of the leakage is small when the battery is changed before it is fully completed. (Ie when the device says that the battery is exhausted or a sensor stops working.)

• Most common error is that you do not immediately after you change the batteries in a sensor re-started the main unit. It must do so for that when you change the batteries in the sensor to receive the signal a new code. The main unit does not recognize it unless you ask it to listen for new sensors / transducers. This whole procedure is to your head unit should not take signals from your neighbor's donors. Some units have a button function to search for sensors again. Then you can use this function.
  
• Another common mistake is that you get the batteries when they are new does not have full capacity. Note: a standard volt meter will not disclose this error. The voltage must be measured under load. If it does not work, try again with a couple of other batteries in order to exclude this.
  
• Another fairly common error is that the standby batteries wrong. Check carefully arrows or symbols that indicate the plus and minus for each battery. Often 's sitting on the lot. But not always! Depending on how long and they were UPSIDE so has batteries, and perhaps unconscious equipment has suffered. Instead of 4.5 volts, it has been -1.5 V.
• Hybrid batteries of different type / age / new / use is not good.
  

1. Get fresh alkaline batteries. Watch the date stamp when you buy the battery. There should be at least 4-5 years. Otherwise, they are an old residue lot and there was a reason why they were so cheap. By this we mean not the most expensive is best. But the newest is often best, regardless of price.
   
2. Replace the batteries in the first donor.
3. Change the batteries in the main unit or restart immediately. (If you only have the batteries as backup for power cuts, they must not be changed, but the main unit must always be restarted if there is a search function.)
4. It is now clear.
