Charging the battery
The removable rechargeable Lithium-ion battery is partly charged when the instrument
leaves factory. It should be fully charging before first time use. If the battery has been stored
for longer than six months, it should be charged again before use. STONEX recommends
charging the battery for five hours to recharge it fully.
Charge the battery in the handheld, or, if you have a spare battery, you can charge it outside
the handheld.
To charge the battery:
1. Connect the connector of the AC adaptor cable to the battery and the power plug to
an AC power outlet.
2. Turn off the handheld or put the handheld in Standby mode.
Note
:
STONEX recommends that you charge the handheld at or below normal room
temperature (0 to 30° C).
3. Leave the battery to charge. It may take up to five hours for the handheld to charge
completely.
When the battery is charging inside the handheld, the Power LED on the front cover is
flashing green.
When the battery is fully charged the Power LED is solid green.
The Power LED on the keypad on the handheld indicates the battery power or charging
status as shown below (Table 2.2.1 – Handheld/Battery state through LED):

Note
:
During normal charging the battery may become hotter than the maximum
temperature allowed (40° C). If this happens, charging is automatically suspended until the
battery cools and then charging automatically restarts. During this time the battery icon in
the title bar shows
, to indicate that the handheld is running on external power. It may
take about one hour for the battery to cool.
Avoid keeping the battery at full charge at high temperatures.
Note
:
The life of the battery can be significantly shortened if power is constantly supplied to
the handheld. To avoid this issue, connect the handheld to an external power source only
when the battery requires charging. Once fully charged disconnect the external power source
and allow the battery to discharge through normal use.
