Troubleshooting
Firstly, ensure that the
baeries have power using a
baery charge gauge.
If the baeries have no power,
replace the baeries.
If the baeries still have
power, check to see if the
baeries have been inserted
correctly into the baery
pack.
Check For CR2032 Baeries
Using The Flat Baery Pack
Inside the battery pack is a symbol
indicating which side the (round) CR2032
battery should be inserted. Check that
the “+” side of the battery pack has
the battery with the “+” symbol facing
downwards.
On the opposite side, the “-” side of the
battery pack should have the battery
flipped upside down, that is the “+” symbol
facing upwards
