a fresh one but you may still continue to use the receiver for
a while.
With only about 5% of remaining power (red area), a new
message will pop up: “Main Battery Very Low”. Tap
Dismiss
in
the task bar to continue using the receiver. Ashtech however
recommends that you turn off the receiver and replace the
battery.
With only about 1% of remaining power, the receiver will
switch off, meaning the battery is no longer charged enough
to ensure proper operation of the receiver. Ashtech
recommends you do not go that far in the use of the internal
battery as there is a risk of losing part of your field data.
In case of long-time storage, remember Li-Ion batteries must
always be recharged regularly, about every six months. This is
to prevent irreversible damage of the batteries.
Battery Charging Scenarios
The battery can be be charged in two different ways:
•
From the power line, through the AC adapter and USB
cable provided. This configuration offers fast battery
charging, with around 700 mA of DC charging current.
•
From an office computer connected to the receiver
through a USB line, using the same USB cable provided.
According to the USB 2.0 specification, the DC current
delivered will be limited to 500 mA, which means it will
take longer to charge the battery from a computer’s USB
port than from the AC adapter.
You can ask the receiver not to allow the charging of the
battery through the USB port when this port is connected
to a computer. To do this:
– Press the Windows key
– Select
Settings, System
,
Power
– Clear the option:
When equipment opens and links to PC,
do not carry out battery charging
– Tap
OK
.
