Performing the Audio Battery Test
Your
SIIADOWx2
is equipped with an automatic battery test circuit so that you can
always be sure you are getting top performance from it. The battery should be checked
after the detector has been on for about 10 minutes and then periodically if you are using
the detector for long periods.
To activate the Audio Battery Test, simply turn the detector off momentarily and then
back on again. If the battery is fresh, the detector should emit a continuous and loud
'beep" sound that lasts for about 4 to 5 seconds, and then slowly fades into silence. As the
battery ages, this sound is less intense and fades out more quickly. When you hear only a
brief "buzz" or no sound at all, replace the battery with a fresh one.
If you prefer, a rechargeable Nickel-Cadmium (Ni-Cad) battery can be substituted for
the standard 9-volt alkaline battery. Individual 9-volt size Ni-Cad cells, as well as the
chargers for them, are readily available at most electronic supply stores. They are
installed into your detector in the same manner as non-rechargeable batteries. The Battery
Test sound on a Ni-Cad battery will be weaker than an alkaline battery in the beginning,
but will not weaken much with use.
