Charging the built-in batteries:
The ESD1 has eight built-in rechargeable batteries 9Ah NiMH. You charge the
batteries by connecting the included power cable. Make sure that the charging
switch is set on ‘ON’. When the charger is connected, the LED marked ‘Charge’
will be lit. Charge the ETS2 until the LED turns green. The process usually takes
about eight hours if the batteries were flat when you started. If you want top
charged batteries, you may continue the charging for 1 or 2 hours more. The
batteries will not be damaged by being connected to the charger for a longer
period of time.
The LED marked '
Battery
' indicates the remaining battery capacity. A red light
indicates a battery capacity of less than 30%. An orange light indicates a battery
capacity of 30--60%. A yellow light indicates 60-90% capacity, and a green light
indicates that the battery capacity is more than 90%.
Surroundings
The ETS2 is not waterproof, so make sure that no water seeps into the
connection ports on top of the unit. You may use the ETS2 in temperatures as
low as -20 °C, and the unit may be placed outside in rain and snow - as long as
the lid is locked.
