Symbol Indicating Devices with ESDS Components
The following measures will help to protect ESDS components from damage and malfunction.
When preparing to dismantle or install devices:
Ground your body (for example, by touching a grounded object) before touching sensitive devices.
Ensure that you wear a grounding strap on your wrist when handling such devices. These straps must
in turn be attached to an uncoated, non-conductive metal part of the system.
Use only tools and devices that are free of static electricity.
When transporting devices:
Devices must only be touched or held by the edges. Never touch any pins or conductors on the device.
When dismantling or installing devices:
Avoid coming into contact with persons who are not grounded. Such contact may compromise your
connection with the earth conductor and thus also compromise the device’s protection from any
static charges you may be carrying.
When storing devices:
Always store devices in ESD-proof ("antistatic") bags. These bags must not be damaged in any way.
ESD-proof bags that are crumpled or have holes cannot provide effective protection against
electrostatic discharges.
ESD-proof bags must have a sufficient electrical resistance and must not be made of conductive
metals if the device has a lithium battery fitted on it.

3 General Information about LANTIME
LANTIME stands for Local Area Network Time Server. The LANTIME provides an absolute and highly precise
time reference in a TCP/IP network (stratum 1 server). The time is made available to all NTP clients via
the NTP protocol (Network Time Protocol) and allows easy integration of an absolute time reference into an
existing network.
The individual LANTIME variants differ mainly in the time reference source used. An external radio clock,
a built-in GPS, GNSS (GPS, GLONASS, Galileo, BeiDou), or GNS-UC (only GPS and Galileo) satellite re-
ceiver, an IRIG time code receiver, a long-wave radio receiver (DCF77, MSF, WWVB), external NTP servers, or
a hybrid DCF77/GNSS receiver system can be used as a time reference source. A GNSS-synchronized LAN-
TIME, for example, consists of a GNSS satellite receiver, a single-board computer with an integrated network
card, and a power supply unit.
A simplified LINUX operating system is implemented on the single-board computer and is loaded from a flash
disk during the boot phase. All settings can be made using eight pushbuttons and a display*. The time server
can also be remotely configured via network over SSH, FTP, or Telnet. An integrated web server provides access
to the LANTIME via any standard web browser.
*LANTIME M100 time servers do not have a display or function keys. Instead, these systems are configured and monitored via the LANTIME Web
Interface, SSH, Telnet, or FTP.
