Open/close antenna (or protective cap)
48 / 157 DLT-V83 Operating Instructions V2.00
8. Open/close antenna (or protective cap)
The DLT-V83 is normally equipped with an antenna for radio operation. Devices without radio operation
have no antenna and instead have what is known as a "protective cap".
The following interfaces are located underneath the antenna or protective cap:
− Service USB
− CFast
− Mini SIM card slot
8.1. Avoid Property damage
NOTICE: Property damage
Protective caps or antennas:
− are only permitted to be removed for servicing purposes, e.g. to install software updates.
− are only permitted to be removed by qualified expert personnel.
No objects or liquids are permitted to enter the opened DLT-V83.
The device is only permitted to be operated again once the protective cap or antenna is
properly sealed again; only then is the protection class guaranteed.
When opening and closing, proceed as described in the sections below.
8.1.1. Disconnecting from the electric power source
− Switch off the DLT-V83 before the protective cap or antenna is removed.
− Only insert/remove the mini SIM card, CFast card and USB stick when the device has been
completely de-energized.
Please note: For DLT-V83 devices with integrated UPS the device may be in operation despite the
disconnecting device being actuated, since it is supplied with power by the UPS. Likewise, the
peripherals that are supplied by the device are also not currentless as long as the DLT-V83 is being
provided with power by the UPS.
