How to differentiate Fixi SMS and Fixi Plus
Here is a description of how you can tell these two products apart.
A) If you have a value code for the product, you have a GSM Fixi Plus. If so, you can control the product with MinHytte.
B) Press the F button. If the light comes on immediately you have a GSM Fixi SMS (remember to turn off F again). If you have to press and hold the F button for about 5 seconds before the light comes on you have a GSM Fixi Plus
C) Take a look at the silver label at the bottom of the product. Old GSM Fixi SMS has model number 300-8090V16 to 300-8090V19 while new GSM Fixi Plus has model number 300-8090V20.
D) Turn off the power to the product. GSM Fixi Plus has Inbuilt battery and will remain on for a few hours after a power failure (the control LEDs will still be on). On GSM Fixi SMS the control LEDs will go off as soon as the power is disconnected (also remember to disconnect -BP12- battery backup if present).
E) Open the cover. If there is a battery directly under the cover you have a GSM Fixi Plus.
