Advantech Dlog DLT-V72 Series Startup Manual page 11

Prevent physical damage due to deep discharge.
Storing the battery packs incorrectly will cause them to discharge completely (deep discharge)
and thus damage them irreparably.
To prevent a deep discharge:
− Remove the battery pack from the battery pocket, if the DLT-V72 is not used for a longer period
of time (more than one month).
− Charge the battery pack in the DLT-V72 device every six months.
5 HF RADIATION
Only applies to devices with radio equipment: Danger of radiation.
DLT-V72 devices with radio equipment emit high frequency energy (abbreviation: HF).
To protect persons and domestic animals against HF radiation:
− Mount the DLT-V72 so that persons and domestic animals maintain a minimum distance of
20 to 50 cm from the radio antennas.
− Ensure that persons observe this minimum distance when operating the DLT-V72.
− High frequency energy can interfere with technical devices. For this reason, do not use the
DLT-V72 in the vicinity of pacemakers or other medical devices.
− Only operate the DLT-V72 with radio equipment that is approved by the manufacturer for this
device.
− Make sure that the transmission power and the radio frequency of the DLT-V72 comply with
the regulations for the respective country where the device is deployed.
− Observe all applicable regulations for your deployment location/country with regard to
operating channels, radio frequencies and the maximum permissible transmitting power.
Responsibility for this lies with the company operating the DLT-V72. The regulatory authorities
in the relevant country can provide information on this.
Any modifications to the DLT-V72 radio equipment which are not expressly approved by the party
responsible for the compliance can lead to the withdrawal of the operating license for this device.
