Devon Tread 1, Owner'S Manual

Page: 22 / 224

• Is the correct power adapter being used?
All the chargers require the same 12 Volt 0.65
Amp adapter.
• How long was the watch on the charger?
Normally it should take about 5-6 hours to
fully charge the Tread 1. Charging overnight
(12 hours) can help ensure the watch is fully
charged. It is most efficient to charge the
watch when it is off, or at least in quiet mode.
• Is the watch presently cold?
Lithium-Ion batteries are sensitive to excessive
cold. The effective capacity of the battery
decreases rapidly as temperature drops below
0°C.
• Is the watch warm or hot when removed from
charger?
Some warming is normal as a result of the
energy dissipated when charging, however
if the watch is exceedingly warm (too hot to
touch) this may indicate a serious problem. The
charger should be immediately unplugged and
the watch and charger returned for testing and
service.
