Operation

Power
The VBOX II can be powered from a wide range of voltage sources including the Vehicle Cigar adapter, the supplied Ni-Mh battery pack or other source
provided by the user. The maximum operating voltage input must not exceed 18V DC. Failure to observe this could result in damage to the VBOX.
charge time. When the battery is fully charged, the 100% led will remain illuminated, and the charging led will turn off. Occasionally the battery will turn the
charging back on to keep the battery at full capacity. To check the state of the battery charge; press and hold in the white button on the side of the box. There
are four LED's which will light up indicating how much charge is left in the battery. 100% LED indicating 100% charge, 75% led indicating up to 99% charge,
50% led indicating up to 74% and 25% led indicating up to 49% charge. When the battery is at a level not suitable for powering the VBOX, the 25% led will
flash.
The battery can be connected to a charger, and also the VBOX at the same time. This allows the battery to be charged whilst the external source is powering
the VBOX. In such a situation, you can power the VBOX from the cigar lighter, with the battery acting as a back up if the ignition is turned off which
sometimes stops the power to the cigar lighter.
When the battery is close to fully discharged, the VBOX will give an audible warning by a slow series of beeps from the internal buzzer. You should have
around 5 minutes of time left when these beeps begin.
Please also note that during extended use, the VBOX II case may become hot. This is normal, however it is good practice to mount the VBOX II in a
position where it has sufficient airflow around the case.
The battery pack is a 6v 3.8amp hour Nickel Metal Hydride unit, with a built in charging and monitoring circuit.
The battery is plugged into the two pin power socket on the front of the VBOX to provide power for up to 6
hours (4 hours with the display attached).
The battery pack can be charged via two methods, either by plugging the VBOX cigar lighter adapter into the
pack, or by using the mains charger. The battery pack can be either discharged fully and then re-charged, or
partially discharged and then re-charged, there is no memory effect on NiMh batteries.
To protect the battery cells from damage, the battery will only charge when the temperature range is between 0
& 46°C. If whilst charging the internal temperature of the battery reaches 46°C, the charge will be turned off
until the internal temperature reduces to 43°C and the charge status led (25% 50% , 75% or 100% ) will flash.
The charge will then automatically restart.
Whilst charging, the 25%, 50%, 75% and 100% will illuminate in succession to give an indication of the total
